Metric JIS Standard Lighter Load Yellow Color Spring / Rectangle Springs for Injection Mold
Discraption
Springs are widely used in stamping dies, metal die-casting dies, plastic molds and other elastic precision mechanical equipment, automobiles and other fields.
The material of die spring is usually chromium alloy steel, because its characteristics of high temperature resistance, rigidity and long service life.
Quick Details
All of our springs are manufactured according to Japan JIS industrial standard, and customized size is welcome.

Treatment
The following processes are the treatment to ensure product quality.
Pressure treatment:
The spring to do more than three times of pressure treatment, eliminating the internal stress before use, no spring deformation, shorten the breakage and other phenomena.
Strengthened treatment:
Spring surface strengthened shot peening treatment, improve the strength of stress concentration point, prolong the fatigue life of the spring.
Surface treatment:
Adopt advanced color electrophoretic paint process, conform to European SOS standard, make the product paint surface even, adhesion is stronger.
