Torsion spring features and advantages

•  3 months superior quality raw material stocked, meanwhile, was introduced advanced production  equipment to make kahuan spring fatigue resistant,high temperature resistant and good toughness.
•  The springs of shape is rounded edges rounded rectangular cross-sectional, which could reduce the  stress concentration at high speeds.
•   The high pressure processing of spring e handle more than three times,can remove the internal        pressure before use, the phenomena of spring deformation,shorten and fracture won't appear.
•   After surface strengthening treatment,its surface organization structure will become more solid,    the fatigue life of spring will be extened.
•   The spring of life is according to the mould stroke, P1-1 million times, P2-0.5 million times, P3-0,3    million times.
•   The spring's highest frequency of use up to 200 times per minute. Modern mold design, must be equipped with high quality mould spring.
