Laser marking machine is expensive and the marking effect is accurate. The operation of pneumatic marking machine is complicated, but it has a wide range. In recent years, a new type of marking machine is called metal marking machine.
Metal marking machine is also called: electrochemical marking machine, electrochemical marking machine, electrochemical marking machine, electro-etching marking machine, electro-etching marking machine, metal engraving machine, engraving mark, metal engraving machine, electro-etching marking machine, printer, electric etching machine, marking machine, engraving machine, etching machine, electro-engraving machine and electric etching machine.

In 2008, Shanghai Feisu Tool Co., Ltd. developed the world's first single-chip pneumatic marking machine (no computer). [ 1]?
Reason:
Pneumatic marking machine: the computer controls the printing needle to move along a certain trajectory in the X and Y two-dimensional planes, and at the same time, the printing needle makes high-frequency impact motion under the action of compressed air, so as to print a mark with a certain depth on the workpiece. Pneumatic marking machine-marking features: large depth, direct marking output through computer. Pneumatic marking machine-marking material: any metal or nonmetal. Pneumatic marking machine-typical applications: automobile parts, nameplates, signs, etc.
Electrochemical marking machine: This equipment applies electrochemical principle to print marks on various metals, such as grinding and polishing of metal surfaces such as iron, stainless steel, carbon steel, alloy steel, tool steel, cemented carbide, aluminum, copper-aluminum alloy, chromium plating, nickel plating, zinc plating, Fa Lan, French black and so on. Used for printing trademarks, product names, technical indicators, manufacturers' names and safety matters, and also used for making high-grade stainless steel signs and logo shells.
Advantages of electrochemical marking machine:
Its advantages are formality, transparency, durability, no discoloration, no shedding, high temperature resistance and no fear of organic solvent scrubbing. No matter the size, plane, cambered surface or sheet of the product, the printing is fine, the depth is 5- 100um, the operation is simple, and it can be completed in a few seconds without drying and curing. There are exquisite logo to improve the appearance of products. Enhance the anti-counterfeiting ability of products, facilitate quality and establish a famous brand image.
Basic operation method:
① Connect the marking head and alligator clip to the machine respectively;
② Prepare the electro-printing template.
(3) Immerse the marking head (positive electrode connected to the machine) in the marking liquid and press it on the workpiece (negative electrode connected to the machine) through the template for several seconds;
Exquisite and eternal patterns appear, as simple as stamping!
Identification features:
Arbitrary mode text;
The accuracy is extremely high. English words with a word height of only 0.5mm are still very clear and burr-free (the resolution of ECM-800 is as high as 0.04mm/600dpi, and the indentation depth is 0.0 1~0. 1mm). The marking effect is completely comparable to laser marking, and the color is usually deeper than laser marking.
Bid is resistant to high temperature, not afraid of any organic solvent corrosion, and will never fade or fall off;
As small as a drill bit with a diameter of 2mm, as large as a steel plate of several square meters; Plane or cambered surface; It is easy to be marked.
Examples should be used:
Hardware tools: knives, scissors, pliers, hammers, screwdrivers, wrenches, woodworking chisels, etc.
Measuring tools and tools: drill bits, saw blades, taps, carbide tools, turning tools, steel rulers, milling cutters, etc.
Mechanical parts: gears, bearings, valves, steel pipes, pipe joints, fasteners, instrument parts, industrial spare parts, screws, pneumatic components, medical devices, stainless steel plates/nameplates, panels, etc.
Kitchen and bathroom hardware: faucet, cooker, range hood, sink, food processing equipment, etc.
Civil products: stainless steel cups, pots, tableware, clocks, glasses, stationery, souvenirs, locks, steel and wood furniture, etc.
Applicable metal types: (including almost any metal with a conductive surface, if the nonmetallic surface is plated with a metal layer)
Carbon steel, Masteel, alloy steel, high speed steel, stainless steel, cemented carbide, aluminum alloy, copper, etc.
Chromium plating, nickel plating, zinc plating, black titanium plating, blackening and other materials;
Sand blasting, polishing, grinding and wire drawing of various metal surfaces.
Advantages of electronic printing bidding:
Compared with laser-low cost, high speed and equivalent marking effect.
Compared with ink screen printing, it is firm and never falls off.
Compared with the traditional galvanic corrosion, the clarity is greatly improved; The PH value of the electroprinting marking solution is basically neutral, which does not hurt the skin and will not rust due to the marking solution.
Compared with steel seal, the accuracy is greatly improved; No matter how hard the metal is, it can be easily marked without destroying the flatness of the metal surface and the stress of the metal workpiece.
Several characteristics of electronic printing marking machine;
Small and beautiful equipment, stable and reliable quality;
Original overload automatic protection device and fan cooling device;
The template is made of high-quality imported raw materials, with long service life and suitable for mass production;
There are all kinds of marking liquids, and there are special laboratories: copper does not fade, aluminum is clear, workpiece blackening does not affect the surrounding blackening layer, stainless steel has good blackness, and steel does not rust.
Consumables are low in price and stable in quality.
Liquid marking machine, solid marking machine,
The laser marking machine mainly uses CO2 laser. The advantages of this laser are: no need for cooling equipment, simple maintenance, low price, long service life and high conversion efficiency. Disadvantages are: the printing effect is not good enough, there is a lot of smoke and dust when printing plastic sealed pipes, and metal cannot be printed, and the printed lines become thicker when using long focal length. Another kind of fiber laser is widely used, which has the advantages of stable operation, long service life, high conversion efficiency and thin printed lines. The disadvantage is that it is expensive.
Air impact sign
The marking machine consists of a single-acting cylinder, and the head is equipped with a steel die. The steel die impacts on the parts to be marked through the high-speed movement of the cylinder. This kind of marking machine has low investment cost, high degree of automation and environmental protection. Very easy to integrate into automated production lines. Multiple fields such as station number, serial number, product serial number and production date can be marked. The modulus of steel characters can reach 40 characters in a single mark.
The marking force varies from 1 ton to 8 tons, and each model has different choices such as single letter, multi-letter and digital marking machine. Moreover, the position sensing switch can be installed according to the customer's requirements, and the corresponding digital signal can be returned after each marking. The daily maintenance cost of pneumatic stamping and cylinder marking is very low, but the steel die needs to be replaced after a certain number of years of use. Others are generally fine.
