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.

Compression and load

The maximum compression of this series of springs is 48% of the free length. Load = elastic coefficient * compression, please contact us for more information.

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.

Attention

Usually, the proportion of service life depends on the spring and compressed, probably relations are as follows,3 points should be paid attention to prevent premature failure of the spring:

1.Maintaining initial compression more than 1mm

2. Prevent any other articles from the middle of the spring

3. Keep vertical compression to prevent bending
