Brand image is built on the words and deeds of employees
Brand is the carrier of corporate culture, a highly concentrated product of corporate system culture, quality culture and ideological culture, and the long-term accumulation of corporate behavior and spirit. The brand image of an enterprise is established bit by bit through the daily work of each employee of the enterprise.
Passionate service brings customers value-for-money satisfaction
Passionate service comes from the bottom of our hearts, a service that can move consumers. It is manifested in enthusiasm in language, enthusiasm in behavior, and sincerity in emotion. In effect, it can provide consumers with value-for-money satisfaction, thereby living up to our God. Enthusiastic service can demonstrate the brand charm of the company and help us win more reputation.
Minimum time and minimum investment
This is the most basic requirement for every employee. When we do any work, if there is no time constraint, procrastination, mutual pushback, and lack of efficiency, then nothing will be accomplished. Procrastination and prevarication is a bad habit. Time is the biggest cost. Achieving goals with the least time and the smallest investment is our unremitting pursuit.
The image of a professional spiritual expert is perfect in details
In today's world where products and services are becoming more and more homogeneous, perfection in details is a winning move in corporate competition. Perfect details reflect a professional quality, and only those with professional training and spirit can cast perfect details.
People-oriented
People-oriented has very specific content: employees are brothers and sisters, family members are loved ones, and customers are relatives and friends. They should be treated with kindness, kindness and sincerity, and with integrity Treating everyone is the principle of life.
Intention is the principle of doing everything well
If you do things with your heart, if you don’t do things with your heart, you will not be able to handle even small things. Whether a person is careful or not can be judged by how well he does some details. Work is not something we do to make a living, it is something we do with our lives. There is no humble job, only humble work attitude, and work attitude depends entirely on ourselves.
Considering obedience as a virtue
Every employee must obey the arrangements of his superiors. Obedience is the first step in action. If the subordinates of a team cannot unconditionally obey the orders and arrangements of their superiors, they will not be able to achieve the same goal. On the contrary, they can exert their super execution ability and make the team better than others.
Leave complex work to yourself, leave simple work to colleagues, and give all the enjoyment to customers
This embodies a noble personality charm and sentiment, without any traces of it. Not benefiting oneself, only benefiting others. Real service is to make things easier for others, rather than causing trouble to others. Pneumatic rivet gun

The birth of the threaded sheath has achieved the goal of high-strength connection of low-strength metal materials. The thread sheath is made of high-quality stainless steel material and has the characteristics of high wear resistance and tensile strength, low thread friction, high surface quality, anti-corrosion and excellent heat resistance. Products comply with national standards, aviation standards, military standards and internal standards of large enterprises, etc. As long as materials with low shear strength are used (such as aluminum, aluminum-magnesium alloy, plastic, etc.), thread sheaths can be used for thread reinforcement. Typical applications include: automotive industry, electronics industry, pharmaceutical industry and aerospace industry, etc. .
Locking thread sheath
Self-locking thread sheath: Self-locking thread sheath can only be used with screws of higher strength level (grade 8.8 or above). Screws with high strength levels generally need to be lubricated.
Advantages of thread sheath
Wear resistance, the thread sheath is made of austenitic chromium-nickel steel (tensile strength ≥1400N/mm2). The threads have a high surface quality, which makes the friction between threads low and stable, thus ensuring the durability and wear resistance of the threads. Repeated tightening with the same tightening torque will produce a stable prestress, which can better utilize the yield point of high-strength screws, so the torsional stress is also significantly smaller. Compared with cutting threads, the surface roughness of thread sheaths is reduced by 90%.
Stronger assembly performance, the variability characteristics of the threaded sheath enable it to evenly distribute load and tension, so it has a good spiral rise angle; the entire length of the threaded sheath can be used to balance the thread pitch And the defects of the spiral rising angle itself, so the ideal force transmission is achieved between the screw and the nut, and the life of the contact thread is also greatly extended. This can be used in both static and dynamic working states.
Corrosion resistance and heat resistance, the material properties of the thread sheath ensure that it will not lock or clamp the thread under normal working conditions. Thread sheaths made of nickel, with or without coating, can be used for threaded connections subject to thermal stress and can prevent springing and breakage even under high temperature conditions. The new high-strength aluminum thread sheath eliminates contact corrosion and is especially suitable for corrosion-prone materials such as magnesium
