Stamping mold manufacturing process

A stamping die is a tool used in the processing of metallic and non-metallic sheets to produce separation or molding of the material by applying pressure to obtain a part of a certain size and shape. Depending on the type of stamping die and the nature of the process, they can manufacture a wide range of products. The process of manufacturing stamping dies is a complex and sophisticated one, involving several steps to ensure the functionality and durability of the dies.
First, the material, size, shape and other requirements of the stamped part need to be clarified. This step is usually done by the product designer, who communicates with the stamping die designer to ensure that the design direction is consistent. The designer determines the stamping process and mold design plan based on product characteristics, such as wall thickness and curves. This includes developing a detailed product process, such as punching, bending, etc., and considering the number of products to determine the appropriate tooling design. After determining the product process flow, the designer starts to conceptualize the die structure, including upper and lower dies, shear edges, convex packages, etc., and draws detailed drawings of the die, such as front view, top view, side view, etc. . Select suitable mold materials, such as MoCr cast iron, MoCr, etc., and carry out preliminary machining, including milling six sides of the angle ruler, leave grinding amount, etc., to ensure the quality of the material and the accuracy of the mold, mold parts, such as convex die, concave die, crimp ring, etc., need to be accurately processed, including CNC machining, electric discharge machining (EDM), etc., to meet the design requirements.
The machined mold parts need to be accurately assembled to ensure the alignment and accuracy of the components. Adjustments and optimizations may be required during assembly to ensure the overall functionality and durability of the mold. Once assembled, the mold needs to be tuned to ensure its performance during the actual stamping process. This may include adjusting the die clearance, testing the press force and checking the quality of the stamped part. The die is run on the actual stamping equipment to check the dimensions and quality of the stamped parts. Depending on the results of the mold trial, further adjustments and optimization of the mold may be required. After the mold debugging is completed, mass production can start. During the production process, strict quality control is required to ensure that the stamped parts meet the design specifications and quality standards. During the use of the mold, regular maintenance and repair is required to maintain its performance and prolong its service life.
