Automotive parts injection mould
The quality and performance of mold materials are important factors that affect mold quality, life and cost. In recent years, in addition to the continuous introduction of a variety of high toughness and high wear resistance cold work die steels, flame quenched cold work die steels, and powder metallurgy cold work die steels, it is worthwhile to use cast iron materials for large and medium-sized stamping dies abroad. Concerned about the development trend. Nodular cast iron has good toughness and wear resistance, its welding performance, workability, surface hardening performance are also good, and the cost is lower than alloy cast iron, so it is more used in automobile stamping dies.
The bumper mold adopts an internal fractal structure design. Compared with the traditional outer fractal structure design, the inner fractal design has higher requirements on the mold structure and mold strength, and is more complicated. Correspondingly, the bumper mold design concept produced by the inner fractal structure mold is more advanced.
