Die spring is a type of high-performance spring specifically developed for the mold design and manufacturing industry, primarily used in pressure control and support functions during processes such as mold forming, die casting, injection molding and stamping. Since die spring is often required to endure frequent compression and impact, it is designed for exceptional durability and stability with excellent performance in high-pressure and high-frequency working environments.
Die springs are typically made from high-strength spring steel, stainless steel or other corrosion-resistant alloys, and undergo rigorous heat treatment processes to improve their hardness and wear resistance, which ensure they won’t deform or break after extended used. Common types of die springs include compression springs, tension springs, torsion springs and constant force springs, with specific selection depending on the mold’s workload, precision requirements and working environment.
We offer a wide range of standard and customized die springs to meet the specific needs of various mold designs. Each die spring will undergo strict quality control and precise testing to make certain it provides outstanding elasticity, durability and high fatigue resistance. Whether in high-temperature, high-pressure or high-speed mold production, die springs offer reliable support to ensure the efficient operation and long service life of molds.
With advanced manufacturing processes and customized designs, our die springs are widely used in industries such as automotive, electronics, packaging and medical fields, serving as one of the core components in mold manufacturing and forming processes.
