All molded plastic compression springs are color-coded according to their respective standards. The color code indicates the load that can be placed on the die spring at a certain percentage of compression. So far, there are three color codes with different scales. ISO stamping spring color code, JISS mold spring color code, American mold spring color code.

What's the Difference Between Die Springs?

All die sets for ISO, JIS, and US springs are manufactured for optimum service life. JIS die springs are made of trapezoidal wire crossings. ISO die springs are made from rectangular wire. Both ensure long service life and high spring performance at high loads. High-Quality Round Wire Die Springs are engineered and a minimum of 5% free length preload is recommended to ensure longer life and higher spring performance.

What are the applications of die springs?

Die springs are named for their use in punch press die sets, where the die sets provide pressure to hold the target material in place as the press punches holes in the substrate. If the die set cannot provide a yield to the punch, the punch may be damaged; if it provides too much yield, the material will not be pierced. Die springs are occasionally used in the transportation and agricultural industries.
