Die Springs – High-Force, High-Fatigue Compression Springs
About the Product
Die springs are heavy-duty, rectangular wire compression springs specifically engineered for applications requiring **high loads in restricted spaces** and demanding high fatigue life. They are often color-coded to indicate load rating—from light to extra heavy—allowing for easy selection and installation in progressive dies, heavy machinery, clutches, and brakes. Due to their rectangular cross-section, they can support significantly higher forces than standard round-wire compression springs of the same size.
- Rectangular wire cross-section for maximum force.
- Color-coded classification for load capacity.
- High fatigue life and low working stroke capability.
- Suitable for high-temperature and extreme environments.
Our die springs are manufactured from chrome-alloy steel, providing superior durability and performance under heavy dynamic loads. They are categorized into four standard load ratings—Medium, Heavy, Extra-Heavy, and Super-Heavy—to meet precise application requirements in metal forming and industrial stamping machinery.
