Product Description

Mold springs find extensive application in various fields such as stamping molds, metal die-casting molds, plastic molds, and precision mechanical equipment with elastic motion. The die spring is typically made of chrome alloy steel, which offers high temperature resistance, rigidity, and durability.

Different standards exist for mold springs, including Japanese, European, German, American, and polyurethane springs. Generally, when referring to mold springs, rectangular mold springs are meant. These springs are characterized by their small size, excellent elasticity, high rigidity, and precision. They are made from rectangular production materials and have a distinguishable color spray on the surface to indicate different loads, resulting in an aesthetically pleasing appearance.


Standardized mold springs adhere to production standards such as ISO9001:2000, Japanese JIS, ISO10243, and NAAMS (North American Automobile Metric Standard). Springs produced according to these standards are categorized as Japanese standard springs, American standard springs, European standard ISO10243, and German standard mold springs.

Metal spiral mold springs are widely utilized in molds, fixtures, industrial clutches, brake components, and various mechanical components. Japanese standard springs are classified based on load capacity, with DB brown mold springs for overweight load, green mold springs for heavy load DH, red mold springs for medium load DM, blue mold springs for light load DL, yellow mold springs for lighter load DF, and so on. International standard classification includes SJL green mold spring, SJM blue mold spring, SJH red mold spring, SJB yellow mold spring, and others.
