● Spring products are made of the most stable stainless steel 301 material;
● Deeply cooperate with upstream companies in research and development, start special smelting from billets, better grasp the quality of raw materials;
● We are not limited by material, although special material requirements can also be developed and produced.
● equipped with two special slitting equipment (minimum slitting width 2mm, slitting tolerance ±0.05mm);
● We use precision hardness tester, edge grinding machine, spring coiling machine, heat treatment constant temperature furnace（炉）, special detector（检测器） and a series of professional production lines and testing equipment;
● We are China's exclusive independent research and development of spring coiling machine manufacturers. It has been upgraded from the first generation to the eighth generation, doubling the spring life.
● For example, the average market life of dog leashes is between 2,000 and 6,000 times, and our test results are between 30,000 and 100,000 times.
● We specialize in the production of stainless steel constant force spring and any variable force spring, with the highest international standards of production technology.
● From raw material slitting, edge grinding, spring winding, shearing, tail processing and heat treatment, all use automatic industrial machines for continuous production.
● The company has obtained 12 utility model patents（实用新型专利）; 1 design patent; A spring fatigue life test bench equipment invention patent.
Design and application technology
● We can fulfill all reasonable customization requirements. At the same time, we have powerful technology to help customers optimize and solve all the problems of spring application.
● We can do structural design for customers, tailored to maximize the function of the spring.
● We have helped many customers solve practical application problems and multiplied the value of their products.
