Die Springs

Die Spring‑Product Description

Overview

Our die springs are heavy‑duty compression springs specially engineered for mould, die‑casting, stamping and industrial machinery equipment. Made from high‑strength alloy spring steel, these springs stand out with stable elasticity, strong fatigue resistance and long‑term service life under frequent repeated compression.

Material

High‑quality chromium‑alloy spring steel, heat‑treated for outstanding hardness and toughness. Good wear‑resistance and anti‑deformation performance under high‑load working conditions.

Colour‑Coded Load Standard

Light blue: Extra‑light load

Green: Light load

Red: Medium load

Yellow: Heavy load

Brown: Extra‑heavy load

Different colours help you quickly identify load rating for convenient mould assembly and replacement.
