About Die Spring
Die springs are heavy-duty helical compression springs made from rectangular or square wire, designed to handle high loads and stresses in manufacturing machinery, particularly die sets. Offering 30% more load capacity than standard springs, they are color-coded for force ranges, shot-peened for fatigue life, and handle extreme temperatures.
Key Characteristics and Features
Material: Usually oil-tempered steel, chrome alloys, or chrome silicon, often powder-coated for corrosion resistance.
Design: Rectangular wire cross-section allows for greater force and mass.
Ends: Both ends are precision ground to create a flat, square bearing surface.
Color-Coding: Identifies the pressure range (e.g., light, medium, heavy, extra-heavy).
Performance: Shot-peened to prevent fatigue and pre-set to prevent length loss under stress.
Common Applications
Metal Stamping: Providing consistent resistance in punch presses.
Plastic Injection Molding: Holding materials in place under high pressure.
Machinery: Used where high force is needed in limited space.
Selection Factors Die springs are chosen based on hole diameter (the space they fit in) and rod diameter (if used on a guide rod). It is recommended to use as many springs as space permits to reduce deflection and extend fatigue life.
