Industrial Compression Spring / Rectangle Coil Springs Blue Color JIS Standard for Dies set
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.
According to JIS standards, the color and load are as follows:
|Load||Compression Ratio %||Color|
Life length /
According to ISO10243 standards, the color and load are as follows:
|Load||Overweight load||heavy load||Medium load||light load|
Compression and load
The maximum compression of this series of springs is 48% of the free length. Please DO NOT over it.
The load = elastic coefficient * compression, please contact us for more information.

The following processes are the treatment to ensure product quality.
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.
Spring surface strengthened shot peening treatment, improve the strength of stress concentration point, prolong the fatigue life of the spring.
Adopt advanced color electrophoretic paint process, conform to European SOS standard, make the product paint surface even, adhesion is stronger.
