Die springs are widely used

        Spring material: high quality chromium alloy spring steel, this material has high temperature resistance, strong rigidity, long life and other characteristics
         The shape of the material is a rectangular cross section shape, which can reduce the stress concentration when the spring is running at high speed.
        The utility model is widely used in stamping dies, metal die-casting moulds, plastic injection moulds and mechanical equipment with precise structure. The main choice of mold spring 50CrVA. It is the installation of small volume, good elasticity, high rigidity, high precision, the material is rectangular and surface color coating (plating), beautiful appearance etc..
