The Impact Of Mold Life

Design is a key step and initial stage in mold production, controlling the entire process of mold production. Therefore, design also has a great impact on the service life of the mold. Design mainly affects the service life of stamping molds from the following two aspects.
(1) The precision of the guiding mechanism of the mold. Accurate and reliable guidance is highly effective in reducing the wear of mold working parts and avoiding the impact of convex and concave mold scratches, especially for blank and small gap punching molds, composite molds, and multi-station progressive molds. To improve the lifespan of the mold, it is necessary to correctly select the guiding form and determine the accuracy of the guiding mechanism based on the requirements of process properties and part accuracy during design.
(2) Geometric parameters of the cutting edge of the mold (convex and concave molds). The shape, fit clearance, and fillet radius of convex and concave molds not only have a significant impact on the forming of stamping parts, but also have a significant impact on the wear and service life of the mold. The fit gap of the mold directly affects the quality of the punched parts and the lifespan of the mold. For those with high accuracy requirements, smaller clearance values should be selected in the design; On the contrary, the gap can be appropriately increased to improve the lifespan of the mold.
