Our Advantages
-
-
Raw materials
● 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.
-
Production equipment
● 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.
