Die spring includes: Japanese standard, German standard mold die springs spring, spring, spring spring polyurethane, usually refers to the rectangular die spring.

Die springs are widely used in the stamping die, metal die-casting mold, plastic mold and other elastic motion precision machinery and equipment, automotive and other fields.

Die spring material generally used chromium alloy steel. Chromium alloy spring steel has the characteristics of high temperature resistance, high rigidity, long service life.

Rectangular die spring has the advantages of small volume, good elasticity, high rigidity, high precision, material is rectangular, surface color coating (plating) to distinguish different loading, the characteristics of beautiful appearance and so.

The standardization of die spring production standards: ISO9001:2000, Japan JIS, ISO10243, NAAMS (North American car metric standard), according to the spring day different standard production standard, American standard spring spring, ISO10243 German standard die spring etc..
