The following are the quality differences and production of badminton rackets. I hope it will be helpful to you! A badminton racket generally consists of a racket head, a racket shaft, a racket handle, and a joint between the racket frame and racket shaft. With the development of science and technology, the development of rackets is becoming lighter and lighter, the frame is getting harder, and the elasticity of the racket shaft is getting better and better. [Edit this paragraph] The racket shape is the geometric shape of the racket head. Now there are generally three types: the traditional oval shape, the ISO racket shape with a square head, and the enlarged ISO shape with a larger chord surface. [Edit this paragraph] The sweet spot is the best hitting area on the racket surface. When the hitting point is in the sweet spot, it can give you enough hitting power, ball control, and little vibration, and you will feel very comfortable. The size of the sweet spot is very important to players, as it makes it easier for players to hit high-quality shots. The most critical factor in determining the size of the sweet spot is the frame shape. The ISO design makes the sweet spot of the racket larger than that of traditional racket shapes, but the increase in the racket head will bring negative effects in terms of torque and weight. [Edit this paragraph] Hardness: The time the ball stays on the racket when hitting the ball is only four to six thousandths of a second. During the swing before hitting the ball and when the racket hits the ball, the racket shaft has a bending and recovery process, and the ball has flown away from the racket surface before the racket returns to its original position. In the case of the same player strength, the softer the racket stick, the easier it is to bend during the swing before hitting the ball, and the bending amplitude is larger, which drives the racket head to move at a greater angular speed and generates greater hitting power. The harder the racket shaft is, the less power can be transferred to the ball when hitting the ball, but it can also reduce the transmission of hitting shock. As for the racket frame, the harder the racket frame is, the less likely it is to deform and twist when it comes into contact with the ball. It can transmit more power to the badminton while transmitting less vibration. [Edit this paragraph] Torque refers to the amount of twisting on the racket surface when the racket hits the ball. The smaller the torque of the racket, the better the control of the ball. [Edit this paragraph] Weight Each racket should be marked with its weight. The general marking methods are U, 2U, 3U, and 4U. Generally, the weight of full-carbon badminton rackets is mostly 2U (90-94 grams) or 3U (85-89 grams), 4U (80-84 grams), while the weight of aluminum-frame badminton rackets is generally above U (95-99 grams) , there are also a few full-carbon badminton rackets that weigh as low as about 80 grams. Heavier racquets are suitable for players who are more powerful and attack-oriented, while lighter racquets are more suitable for players who are more defensive-oriented. [Edit this paragraph] Balance point If the balance point of the racket is closer to the head, it is called "head-heavy"; if the balance point of the racket is closer to the handle, it is called "head-light". The general balance point is measured from the bottom of the racket upward and is measured in centimeters and inches. According to the principle of mechanics, the weight is directly proportional to the feel of the swing, and the balance point is proportional to the square of the feel of the swing. A head-heavy racket has greater inertia due to the greater inertia of the racket head, and the ball is more powerful but the swing flexibility is slightly less. It is more suitable for offense and is also the choice for golfers who lack strength, because although the head-heavy racket reduces your batting speed, it can make it easier for you to hit the ball to the backcourt. Although a racket with a light head is more flexible, the ball hit is less powerful, and the vibration transmitted by the racket will be greater. It is not suitable for players who hit the ball hard, but is more suitable for defensive and control players and players who pursue speed, because this The continuous swing speed of this kind of racket will be much faster. With the advancement of technology, many new rackets can achieve the same balance point of the same model through precise control of the production process without using balancers. This is also a basic requirement for high-quality badminton rackets. [Edit this paragraph] Length The length of a standard badminton racket is 664 mm, while the length of an extended badminton racket is generally 674 mm. The most important part of the lengthening is the racket shaft and handle. Some models of racket frames are also slightly longer. The advantage of lengthening the badminton racket is that it improves the hitting point, increases the flicker of the racket stick, can hit the smash ball with a larger landing angle and speeds up the ball. It increases the aggressiveness to a certain extent and expands the ball reception. area. However, an extended badminton racket is more likely to cause wrist and arm injuries than an ordinary badminton racket. At the same time, the flexibility of the badminton racket is also reduced, which is not conducive to handling close-fitting balls. [Edit this paragraph] Racket frame cross-section The box-shaped cross-section is an earlier design. Its biggest advantage is excellent ball control performance, but the air resistance of the swing is large. The airfoil cross-section is a design that appeared later and is now the most commonly used. Its advantage is that it has low air resistance and can swing faster and hit fast and fierce returns. Because of its thin cross-section, its ball control is slightly insufficient. .

The third type of semicircular cross-section is the transition design of badminton racket from aluminum frame to full carbon. Its cross-sectional shape is basically the same as that of aluminum-frame racket, and the manufacturing process is relatively easy.

Generally speaking, wing-shaped cross-sections are now the mainstream, and are more advantageous for doubles and hitting aggressive returns, while box-shaped cross-sections can better control the ball. With the development of material technology, badminton rackets with thinner box-shaped cross-sections are now more common in high-end models, in order to strive for faster batting speed and better return control performance. [Edit this paragraph] The joint refers to the joint between the racket frame and the racket shaft. From the appearance point of view, there are T-shaped and Y-shaped joints. From the technical point of view, there are built-in and external joints.

The full-carbon badminton rackets currently used appear to be one piece (no joints can be seen), but in fact most of them use built-in joints, and only a few rackets use joint-less technology. , the disadvantage of no joint is that the racket has poor torque. The frame and shaft are made separately and then connected with joints, which helps to better control the quality, weight and balance of the racket. The external joint is good in terms of strength and torsion, but its weight is relatively large and the stress is concentrated at the joint between the joint and the racket frame, making it the most vulnerable part of the aluminum frame racket. The built-in joint is made of high-strength carbon fiber and connects the racket shaft and racket frame together. It overcomes the shortcomings of external joints, but its process requirements are higher. [Edit this paragraph] Materials Before the 1970s, badminton rackets were basically made of wood and steel pipes. In the 1970s, aluminum alloys were used. Now a large number of new materials are used, such as carbon fiber, titanium alloy, high-strength carbon fiber, etc. These new materials are lighter, stronger, more durable, absorb more vibrations and shocks, and at the same time allow racket manufacturers to have more room to play in the design of racket hardness, ball feel, and hitting performance. [Edit this paragraph] Shopping What kind of badminton brands are there to choose from?

YONEX is the number one badminton supplies brand, including: Kason, Victor, Sotx, Wilson, Finnex... The more well-known brands include Gosen and so on. It is worth mentioning that China has become a manufacturing kingdom in recent years. As feather net manufacturers in Taiwan, especially in my country, have moved their production lines to the Pearl River Delta and the Yangtze River Delta, they have also brought relevant knowledge and technology to the mainland. Now Almost all links in the badminton industry chain are domestic. It can be said that China is not only the largest badminton market, but also has the largest production volume and the best production quality of badminton products in China. But compared to international big names like Wilson and Yonex (whose sponsorship almost monopolizes the national teams of all powerful badminton countries), the brand awareness of domestic manufacturers is still improving.

Senior golfers are able to discern and spend less money to find a good racket. For ordinary amateur players, with the gradual acquisition of badminton racket materials and production processes, domestic brands (including Taiwanese brands) have produced a large number of first-class rackets, which fully meet the requirements of professional and amateur players. The price/performance ratio is quite high. For a racket with the same performance and materials, some so-called well-known brand rackets may be several times more expensive than ordinary brands. Of course, this has a huge advertising and marketing cost factor, and it also takes advantage of novice consumers who are "cheap but not good". Shopping psychology. So learn more about badminton rackets and clarify your own racket requirements. Sometimes you can really find a good racket with high quality and low price for yourself! Jianzhile Badminton Network provides a lot of relevant knowledge for your reference.

The one that suits you is the best, go and choose one!

How to choose a suitable badminton racket based on its performance parameters?

The general principle is that players with low strength should choose soft racket sticks, that is, low-scoring and lighter racket sticks, and offensive players should choose hard and heavier racket sticks. The higher the control performance score, the better. The higher the score in the list, the stiffer the racket, the better the ball control performance, and the easier it is to hit powerful shots.

What do the numbers 2UG3 on the handle of the badminton racket mean?

The xU in front indicates the empty weight of the badminton racket: U-95~100g, 2U-90~94g, 3U-85~89g, 4U-80~84g, generally yonex badminton racket The common weights are 2U, 3U, and 4U. Gx indicates the thickness of the racket handle: G1 is the thickest and G5 is the thinnest.

Why do some badminton rackets have a row of numbers on the handle?

There are two types of numbers on the vertebral handle: 1: There is only a larger Arabic numeral, which indicates the sales area of ??the badminton racket. The only ones I know now are 4-Hong Kong and Southeast Asia, and 3-North America. Region, 5—Mainland China. 2: In addition to the larger numbers, there is also a series of small numbers and English letters. This kind of badminton racket is provided by yonex to national teams. The big numbers in front still represent the region, the small numbers are the numbers of each badminton racket, and finally The English letters represent countries such as: CH—China (CN and CP are sponsors of the Chinese national team), CD—Canada.

What does it mean when some badminton racket models have long, swing power and other logos behind them?

The meanings of these marks are as follows: long—the extended type is 10mm longer than an ordinary badminton racket, which helps players expand their return range, enhance their aggressiveness, deliver tricky short balls, and hit powerful shots. High-angle smashes, power - afterburner type are designed using the enhanced attack power concept (SPT). The top of the racket is heavier and can hit high attack power returns with less force. Light - light rackets generally weigh 3U. The lightweight design of the racket is faster but less powerful than a traditional racket, and is more suitable for defense. The slim frame is only 9mm wide and 5.5mm thick. From a cross-section perspective, it is 25% slimmer than a traditional racket frame. %, it can be called the world’s slimmest badminton racket frame; it can reduce wind resistance by 10% and increase batting speed by 5%. Tour-tour rackets have better materials and better performance than the same model of badminton rackets. Swing Power—(introduction) adopts different elasticities, different weights, and different balance point positions, suitable for different types of players, VF—"vari-frame" variable cross-section racket frame, and the top of the racket frame adopts the wind-breaking type (AR) The design reduces air resistance and improves the hitting power; the bottom of the racket frame adopts a box-shaped (CAB) design, which reduces the hitting torque and enhances controllability. MF-yonex's 2000 new technology "Mega-Frame" is large The racket surface and frame are larger in width and length than ordinary rackets, which greatly increases the hitting sweet spot. MPF—"muscle power frame" muscle-shaped racket frame design, used in new rackets such as Ti-10.

Is the full carbon badminton racket formed in one piece?

Because one-piece molding (jointless) makes it difficult to distribute the weight of badminton rackets reasonably and has poor torque, it is rarely used. As far as I know, only low-end carbonex8000 is used, and the racket frame and racket shaft are manufactured separately and reused. Badminton rackets connected with built-in T-joint technology have much better performance in all aspects.

Is the more expensive the better?

Generally speaking, the price of a badminton racket is related to its materials, craftsmanship and brand. New models are generally more expensive and the price will usually drop a lot after a period of time. Generally speaking, expensive badminton rackets are mainly provided for professional players and may not be suitable for amateur players, and it is difficult for ordinary amateur players to feel the slight differences between different models. So the most important thing is to choose the one you are most comfortable with rather than just looking at the price. Of course, if you don’t consider price factors and want something tangible, you might as well keep up with the latest.

Where are YONEX badminton rackets made?

Yonex badminton rackets are manufactured in two places, one is Japan and the other is Taiwan. If it is made in Japan, there will be the words MADE IN JAPAN and JAPAN on the bottom of the shaft and handle respectively, while it is made in Taiwan. There will only be a MADE IN TAIWAN label on the packaging bag. Also, if it is a YONEX racket not produced in Japan, it will definitely not be marked: MADE IN JAPAN, but rather: designed by yonex japan! or other related similar instructions. Japan, which is particularly industrially developed, has done a great job in this regard! In addition, every fake Yonex badminton racket will have the words MADE IN JAPAN and JAPAN on the bottom of the shaft and handle.

Some badminton rackets sometimes have the word SP printed on the back of the racket model. What does it mean?

The word SP indicates that the badminton racket is sold by yonex Singapore head office. All badminton rackets sold through commercial channels now come from yonex Singapore.

Only the badminton rackets provided to national teams come from Japan, and some of them will flow into the market due to various reasons.

Any badminton enthusiast who has been playing for more than 10 years can look back at the badminton supplies and equipment over the years and it can be said that they have changed with each passing day. Nowadays, many badminton product manufacturers use high technology to design and manufacture badminton products, so that players can enjoy badminton more and achieve better results. For example, the advent of ISO square head rackets and the application of space material titanium are undoubtedly to enable players to hit faster and more lethal balls. If you are now preparing to choose a new racket, you may wish to listen to the advice here, because for a badminton enthusiast, the shape, weight, structure, material, hardness and correct stringing of a racket are obviously More important than its color, packaging and price.

1. Racket shape and sweet point

Racket shape: It is the geometric shape of the racket head. Now there are generally three types: a: the traditional oval shape b: the ISO racket shape with a square head c: the enlarged ISO shape with a larger string surface. There is also a less common WILSON product with a frame that is wider at the top and smaller at the bottom. The "big hammer" shape, this racket shape is transplanted from Wilson's online racket, which is rare and has poor performance, so I won't introduce it here. Sweet spot: The best hitting area on the racket surface. When the hitting point is in the sweet spot, it can give you enough hitting power, ball control, and little vibration, and you will feel very comfortable. The size of the sweet spot is very important to players, as it makes it easier for players to hit high-quality shots. The most critical factor in determining the size of the sweet spot is the frame shape. The ISO design makes the sweet spot of the racket larger than that of the traditional racket shape, 32% larger to be precise. The sweet spot of the racket designed with ISO-MF is larger than that of ordinary ISO. Of course, it is not that the racket head is wider. Bigger is better, but enlarging the racket head will have a negative impact in terms of torque and weight. The ISO head shape is subdivided into two types. One type has a square head with 8 wire holes, commonly known as [large square head] such as YONEX Ti-5, VICTOR LEADER, etc.

The other has 6 holes The wire hole is commonly known as [small square head], and its frame is slightly larger, such as YONEX Ti-6, Ti-8, etc. Their appearance is different, but there is no difference in performance. When using strings with the same tension, the elasticity of the racket with an ISO racket head is greater, while the strings of the ordinary oval racket head feel tighter, so you will find that the same strings and the same tension are better in ISO rackets. Ball strings last longer. At the beginning, I felt that the square-headed feather racket was not very good-looking, but after using it, I found that you will clearly realize the advantages of the ISO racket head when defending, especially when catching and smashing the ball. When smashing the ball, it is better than the traditional oval head. The head of the racket is slightly inferior, but its overall performance is higher. Especially when the hitting point is not in the center of the racket surface, you can deeply appreciate the advantages of the ISO racket shape. This is why more and more players are using ISO racket shapes now. It should be said that ISO racket shapes are the development direction of badminton rackets. My opinion when buying a racket now is to try to buy products with ISO head shape.

2. The relationship between hardness, torque and ball control

Hardness: When hitting the ball, the ball stays on the racket for only four thousandths to six thousandths of a second. During the swing before hitting the ball and when the racket hits the ball, the racket shaft has a bending and recovery process, and the ball has flown away from the racket surface before the racket returns to its original position. In the case of the same player strength, the softer the racket stick, the easier it is to bend during the swing before hitting the ball, and the bending amplitude is larger, which drives the racket head to move at a greater angular speed and generates greater hitting power. The harder the racket shaft is, the less power can be transferred to the ball when hitting the ball, but it can also reduce the transmission of hitting shock. As for the racket frame, the harder the racket frame is, the less likely it is to deform and twist when it comes into contact with the ball. It can transmit more power to the badminton while transmitting less vibration.

Torsion: The so-called torque refers to the amount of twisting on the racket surface when the racket hits the ball. The smaller the torque, the better the ball control.

The relationship between hardness and ball control:

1. Directional control: When the racket hits the ball, the ball can hit back according to the direction or angle of the hit. The harder the racket shaft and frame are, the higher the stability of direction control will be. And when the ball is not hitting the sweet spot of the racket surface, the harder the racket, the smaller the torque will be.

2. Depth control: This refers to the control of the flight distance (landing point) of the returned ball.

Depth control is related to the player's own strength. Under the same strength, the softer the racket stick, the better the depth control. Regular badminton rackets have certain instructions on the hardness of the racket shaft. For example, VICTOR will be marked with flex-18 or 17. The 18 racket shaft is softer. If it is not marked, it is usually 17. Half of YONEX's marks on the racket shaft are in the product manual, but there is no mark on the racket body. The method is based on a 5-point scale. The higher the score, the harder the racket shaft (available in the yy badminton racket classification list). If it is not marked, you can also make a rough estimate from the material. High-strength carbon fiber (High Modulus Graphite) material is harder than carbon fiber (Graphite/Carbon). When choosing a badminton racket, you can also bend the racket shaft with your hand to test the hardness. At the same time, pay attention to the bending point of the racket, so that the closer to the handle, the better. You can also hold the handle and frame head and rotate the racket in the opposite direction (like twisting a towel) to try the racket's torque. Note that you must use force to feel it. Generally speaking, the shafts of current badminton rackets tend to become softer and the frames tend to become harder. The shafts of YONEX's current badminton rackets are much softer than they were a few years ago. I think a softer shaft is better for amateurs.

3. Weight, balance point and length

Each racket should be marked with its weight. The general marking methods are U, 2U, and 3U. Some manufacturers also use their own markings, such as VICTOR's badminton rackets, whose weights are marked as W1, W2, etc., corresponding to 2U and 3U, but the most common one is the former. Generally, the weight of full-carbon badminton rackets is mostly 2U (90-94 grams) or 3U (85-89 grams), while the weight of aluminum-frame badminton rackets is generally above U (95-99 grams), but now there are also a few full-carbon feather rackets. The weight of the shot is as low as about 80 grams. For example, the SR and SA models of YONEX ISO-SWING-POWER-500 only weigh 81 grams. Heavier racquets are suitable for players who are more powerful and attack-oriented, while lighter racquets are more suitable for players who are more defensive-oriented. If you use more of an offensive style of play, the weight of 2U is better. If you use a 3U badminton racket, you will feel that the racket is a little floaty when hitting the ball, and the strength of the ball is not enough.

Racquets of the same weight will feel very different in your hands. This is because the balance points of the rackets are different. If the balance point of the racket is closer to the racket head, it is called [head-heavy]; if the balance point of the racket is closer to the handle, it is called [head-light]. The general balance point is measured from the bottom of the racquet upwards and is measured in centimeters and inches. According to the principle of mechanics, the weight is directly proportional to the feel of the swing, and the balance point is proportional to the square of the feel of the swing. A head-heavy racket has greater inertia due to the greater inertia of the racket head, and the ball is more powerful but the swing flexibility is slightly less. It is more suitable for offense and is also the choice for golfers who lack strength, because although the head-heavy racket reduces your batting speed, it can make it easier for you to hit the ball to the backcourt. Although a racket with a light head is more flexible, the ball hit is less powerful, and the vibration transmitted by the racket will be greater. It is not suitable for players who hit the ball hard, but is more suitable for defensive and control players and golfers who pursue speed, because The continuous swing speed of this racket will be much faster. Of course, if your strength is already close to that of a professional, then you can use a head-heavy racket to increase power and gain speed at the same time. This is why we find that the same model of professional badminton racket is more powerful than the commercial badminton racket we buy. Shen! In order to accurately control the balance point, a high-quality badminton racket will be equipped with a balance weight in the handle after it is formed. Remove the plastic bottom handle at the bottom of the handle, and you will see the lower part of the wooden handle, which is 1/3 of the handle. It is a hollow cylinder in length with a plastic rod embedded inside. Its purpose is to adjust the center of gravity of the badminton racket so that the same model of badminton racket has the same balance point.

However, with the advancement of technology Many new rackets have improved through precise control of the production process, so that finished rackets of the same model can have the same balance point (within an error within the allowable range) without using balancers. This is also a basic requirement for a high-quality badminton racket.

It should be noted that the above descriptions of weight and balance points are made for a brand new racket without strings, additional handles or other appendages.

The length of a standard badminton racket is 664 mm, while the length of an extended badminton racket is generally 674 mm.

The main part of the lengthening is the racket shaft and handle. Some models of racket frames are also slightly longer. The biggest advantage of lengthening the badminton racket is to improve the hitting point and increase the flicker of the racket shaft.

The biggest advantage of lengthening the badminton racket is that it improves the hitting point, can hit the smash ball with a larger landing angle and speeds up the ball. It increases the aggressiveness to a certain extent and expands the area for catching the ball. If you like to smash the ball, The extended badminton racket is indeed a good choice. At the same time, it should be noted that an extended badminton racket is more likely to cause wrist and arm injuries than an ordinary badminton racket. At the same time, the flexibility of the badminton racket is also reduced, especially for handling close-fitting balls, which will give you a little trouble. . But in general, the current development of badminton is mainly about offense, so there are more and more lengthened rackets!

4. The significance of racket frame cross-section and joints

The cross-section of the racket frame has the following three basic forms: semicircular cross-section and multi-faceted parallel cross-section.

The MP series launched by YONEX has improved the design of the wire trough based on these three cross-sections - see MusclePower technology for details. The box-shaped cross-section is an earlier design. Its biggest advantage is excellent ball control performance, but the air resistance of the swing is large. The airfoil cross-section is a design that appeared later and is now the most common design. Its advantage is that it has low air resistance, swings faster and can easily hit fast and fierce returns. Due to the thin cross-section, its ball control is slightly insufficient. , however, modern badminton technology pursues more speed and ferocity, so this design is more popular. The third type of semicircular cross-section design is mainly seen in YONEX’s early and low-end CARBONEX products such as: CARBONEX 6 and below models and CARBONEX 8300, 8200, 8000, etc. It should be said that this design is the transition from aluminum frame to full carbon badminton racket. The cross-sectional shape of the design is basically the same as that of the aluminum frame racket, and the manufacturing process is relatively easy. However, in the later period, YONEX reduced this cross-section and used it for its SLIM rackets, such as the ISO-SLIM10 badminton racket. Its characteristics are: The racket frame is only 9mm wide and 5.5mm thick. From the cross-section point of view, it is slimmer than the traditional racket frame. 25%, which can reduce wind resistance and increase batting speed. The negative impact is that the strength and torsion performance of the racket frame are reduced. My personal feeling is that SLIM10 is more suitable for singles and its doubles feel is not very good. In actual badminton rackets, in addition to using a single frame-shaped cross-section design, combined frame-shaped designs are often used. For example, several models of CARLTON adopt variable-width designs, that is, the racket frames all adopt a wing-shaped design, but the head part is The frame is about 20% wider than the lower frame to increase the attack power of the racket. The PRO-KENNEX LEGENDARY DESTINY model generally adopts a wing-shaped cross-section, but thickens the cross-section by about 4 holes at the 3 o'clock and 9 o'clock positions of the racket frame, and uses spherical rubber particles to reduce vibration. YONEX's VF series adopts a box-shaped cross-section design at the bottom of the racket frame and a wing-shaped cross-section at the upper part to improve the overall performance of the racket.

YONEX's MPF adopts a muscle-shaped (or wave-shaped) design in the string groove of the badminton racket, which changes the stress distribution of the racket frame and strings to improve the performance of the badminton racket.

The connectors are T-shaped and Y-shaped in terms of appearance, and built-in and external in terms of technology.

Before introducing these joints, I want to make one point clear. The full-carbon badminton rackets used today are all one piece in appearance. In fact, most high-quality rackets use built-in joints, and only very few have built-in joints. Some rackets use jointless technology, such as YONEX CARBONEX-8000. My feeling is that the racket has poor torque. Since badminton has high requirements for the accuracy of hitting the ball, the racket frame and racket shaft are made separately and then connected with joints, which is conducive to better controlling the quality, weight and balance point of the racket. The appearance of external joints originated from the emergence of aluminum-frame badminton rackets. External joints are good in terms of strength and torsion, but they are heavy and stress is concentrated at the joint between the joint and the racket frame, making aluminum-frame rackets most susceptible to breakage. parts. Although it is mostly used for aluminum-frame badminton rackets, there are also examples of it being used for full-carbon badminton rackets: VICTOR's APOLLO model is a full-carbon badminton racket that uses an external T-shaped joint. It was adopted when VICTOR's technology for producing built-in T-shaped heads was not yet mature. transition plan. The built-in joint is made of high-strength carbon fiber and connects the racket shaft and frame together. It overcomes the shortcomings of external joints, but its process requirements are higher.

Production process

Step 1: Cut the large piece of carbon fiber cloth into small pieces.

Step 2: Roll the carbon fiber cloth into a circular tube.

Rolling the racket shaft part

Rolling the racket frame part

Step 3: Take the rolled round tube and preform it. The so-called preforming is to make it look like a racket. In this process, the T head is installed.

Step 4: Clean the mold. In order to ensure the cleanness of the product, the mold needs to be cleaned. After cleaning the mold, put it into the hot press table and heat it for 10 minutes. After taking it out, open the mold and wipe the release agent 1:1 Quality, heat the mold for 10 minutes and then cool it to 50 degrees before it is ready to be put into the mold.

Step 5: After the mold is cleaned, it is time to put it into the mold. Open the mold on both sides, open the side panels and take out the correct pre-shaped racket. First, make the molding adjustment on the upper mold (left), then press the frame surface with two fingers from the top frame and perform the flattening adjustment motion toward the lower tee. After it is snug, place it in the lower mold and put it into the correct position. Press the tee with your left hand and push down the middle tube with your right hand into the mold cavity. Make sure the air nozzle is inserted into the mold cavity and the frame surface is moderately tight.

Step 6: After placing the mold, close the mold. The mold must be inserted in one go. You must hear the sound of the upper and lower molds touching each other and open it again to confirm that there is no yarn clamping. Then cover the upper mold and try to press down the upper mold as much as possible before pushing it into the hot press table;

Step 7: After the mold is capped, it should be sent to the hot press table as soon as possible for heating and forming. This process takes half an hour so that the epoxy becomes solid.

Step 8: After half an hour of heating, the product is almost ready, and you can see the primary embryo coming out.

Step 9: Take out the prepared primary embryo. Remove the spilled epoxy from underneath and grind it off.

Step 10: Rough grinding of the feather racket blank, use a file to clean the resin chips on the racket frame.

Step 11: The next step is to drill the wiring holes.

Step 12: After drilling, assemble the wooden handle and pour the prepared glue into the wooden handle.

The mouth of the wooden handle should also be coated with glue.

The initial embryo of the racket must also be coated with glue.

Step 13: After applying the glue, assemble them.

Step 14: When assembling the wooden handle, you need to adjust the level of each plane.

Step 15: After assembling the wooden handle, you can take a rough look at it.

Step 16: Let it sit for 8 hours, they will become a solid body. Next is the fine mold. The fine mold is used to prepare the soil.

Step 17: What is the function of soil replenishment? This is a very critical process.

One: Fill the pinholes on the surface.

Two: It can make the paint have better adhesion, which means that the paint will not peel off so easily.

Step 18: After the soil filling is completed, spray a bright color paint. Then it’s time to assemble the plastic base.

Step 19: Wrap the hand with glue.

Finally pull up the net and one racket is completed
