The requirements of stamping materials for metal stamping parts processing plants around Langfang + the original national standard for raw materials

The metal stamping parts processing plants around Langfang have strict requirements on stamping materials. The surface and internal properties of the stamping sheet materials have a great impact on the quality of the stamped products. Xiaoshuo sorted out the main points for the requirements of stamping materials and shared them with you: ①The thickness is accurate and uniform: the stamping die is precise and the gap is small. If the thickness of the sheet is too large, the deformation force will be increased, and the material will be stuck or even concave. Die expansion and cracking; too thin sheet material will affect the quality of the finished product, and even cracks during deep drawing. ②Surface is smooth, no scars, no scratches, no surface cracks, etc.: All surface defects will remain on the surface of the finished workpiece, and crack defects may extend deep and wide during the process of bending, drawing, and forming, resulting in waste products. ③ Uniform yield strength without obvious directionality: anisotropy (see the plastic deformation of the sheet metal in the drawing, flanging, bulging and other stamping processes, due to the occurrence of different directions of yielding, the amount of plastic deformation is inconsistent, which will cause Uneven deformation, resulting in inaccurate forming and resulting in defective products or rejects. ④High uniform elongation: In the tensile test, the elongation before the neck phenomenon of the sample begins to appear is called uniform elongation. During deep drawing, the sheet material The deformation of any area of u200bu200bthe material cannot exceed the uniform extension range of the material, otherwise uneven deformation will occur. The hardware and raw materials are imported and the original national standard factory, 20,000+ sets of mold customization production experience, monthly 100+ sets of mold processing capacity, 3 million punches per day Sub-production capacity, the stamping accuracy of stainless steel flat washers can reach 0.01mm, and 16 quality inspection layers are strictly controlled. It can quickly solve the time emergency problem of stainless steel flat washers, solve the problem of stamping accuracy, and solve the problem of production quality. Choose, choose to rest assured !
