Springs - Die - Imperial - Medium Duty - Standard

Standard Medium Duty Imperial Die Springs. Colour coded blue. Vapor degassed high tensile strength chromium alloy steel.

  • Heavy duty, high-stress compression springs designed to handle large loads and high temperatures in demanding applications like metalworking dies and production tooling.
  • Unlike standard compression springs, die springs are typically made from rectangular or square wire, offering greater strength and deflection capabilities.
  • Many die springs are colour-coded to indicate their load capacity, allowing for easy identification and selection. An expanded range may be available on special order. Please enquire.
  • Designed for long life cycle with constant high end deflections and shot peened to increase fatigue life.
  • Maximum deflection is 50 percent of the length
  • Efficient operating range is 25 to 40 percent of the length
  • Spring Ends: Squared and ground.
