Mould / Die Springs

Mould / Die Springs are high-performance compression springs specifically designed for use in moulds, stamping dies, and high-load industrial tooling. These springs are engineered to deliver exceptional strength, durability, and consistent performance under frequent compression and high-stress conditions, making them ideal for demanding manufacturing environments.

Applications

Mould and Die springs are widely used in:

• Tooling: Injection moulds, stamping tools, and die-casting equipment.

• Machinery: Press tools, clamping, and ejector mechanisms.

• Heavy Industry: Plastic and metal forming machines.

• Automation: Precision mechanical assemblies and automation systems requiring high-load compression.

Load Classifications & Specifications

• To meet various requirements, our springs are available in standard load classifications:

  • Extra Light Load: Minimal resistance and longer travel; ideal for light-duty moulds.

  • Light Load: Moderate resistance with smooth, consistent performance.

  • Medium Load: Balanced strength and flexibility for standard moulding and stamping.

  • Heavy Load: High force and shorter travel for industrial presses and dies.

  • Extra Heavy Load: Maximum compression force with minimal deflection for extreme stress conditions.

  Materials: Manufactured using high-grade alloy spring steels for exceptional fatigue resistance and dimensional stability.

Quality Assurance

• Rigorous Testing: All mould springs undergo strict dimensional inspection, load testing, and fatigue-cycle evaluation.

• Traceability: Each production batch is traceable and verified for consistency in hardness, tensile strength, and deflection behaviour.

• Compliance: Manufactured to meet international quality standards for high-stress industrial environments.

Heat Treatment & Surface Finishing

• Controlled heat treatment for maximum strength and dimensional stability.

• Shot peening to improve fatigue resistance and surface hardness.

• Oil tempering and precision grinding for consistent compression rates.

• Color Coding: Surface painting or powder coating for visual identification of load class and corrosion protection.
