Zhejiang stamping parts processing, what are the requirements of stamping parts materials + hundreds of precision processing production equipment

The manufacturer hardware in charge of stamping parts processing in Zhejiang said that the surface and internal properties of the sheet metal used in stamping have a great impact on the quality of stamped products. Following Xiaoshuo's experience based on actual production, will take you to understand the requirements for stamping materials: ①The thickness is accurate and uniform. The stamping die is precise and has a small gap. If the thickness of the sheet is too large, the deformation force will be increased, and the material will be jammed, and the die will even be swelled. If the sheet is too thin, it will affect the quality of the finished product and even crack during deep drawing. ②The surface is smooth, no spots, no scars, no scratches, no surface cracks, etc. All surface defects will remain on the surface of the finished workpiece, and the crack defects may extend deep and wide in the process of bending, deep drawing, forming, etc., resulting in waste products. ③The yield strength is uniform without obvious directionality. Anisotropy (see plastic deformation in the drawing, flanging, bulging and other stamping processes, due to the occurrence of all-directional yielding, the inconsistent amount of plastic deformation will cause uneven deformation and inaccurate forming. Inferior product or scrap. ④High uniform elongation. In the tensile test, the elongation before the neck phenomenon of the sample begins to be called uniform elongation. During deep drawing, the deformation of any area of u200bu200bthe sheet cannot exceed the uniformity of the material Extend the range, otherwise there will be uneven deformation, etc. Excellence is the constant pursuit of people. Hardware, 15 years of focusing on Zhejiang stamping parts processing, 2 days for sampling, 3 days for shipment, 4 days for mold generation, 20 design team, free Samples, large quantities, free mold opening, can save customers new products listed companies, stamping processing accuracy can reach 0.01mm, stamping parts quality is guaranteed. It is a metal stamping parts processing manufacturer worthy of your trust.
