All of springs ar e made and processed according to ISO***1; ***0standard. And this is our reputation of supplying the most preci se mould srping and standrad components, the test result of its long life cycle shows that our spring is much more competitive than other products.

The advantages and features of  spring                                                                                                                                                             SPRING MATERIAL
We use good chrome alloy spring material.This kind of material has the feature of high temperature resistance, 
hardness, and long life cycle.
MATERIAL TYPE
The rectangle section which is different from the normal  straight spring. That could reduce the stress while high 
speed traveling.
STRESS TREATMENT
The spring  has 3  times of stress treatment which can eliminate  its  internal  material stress and prevent the spring
from deforming and breaking.
STRENGTH TREATMENT
The surface of spring has been hardened that can enhance the material structure, increase its strength, long life
cycle and reduce its fatigue.
LIFE CYCLE
According to spring compression coefficient, the  product life cycle of JIS is 1million times. The international 
standard ****3 is 3 million times of life cycles.
