Anqing hardware stamping parts exporter, material selection requirements + raw materials imported and national standard original factory

The production staff of Anqing hardware stamping parts exporter said that the surface and internal properties of stamping sheet materials have a great influence on the quality of stamping products. So what are the requirements for stamping materials? Xiaoshuo sorted out some relevant information, and let's take a look at it below: 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 during the process of bending, deep drawing, and forming, resulting in waste products. ③ Uniform yield strength 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 uneven deformation will occur. Hardware, 15 years of craftsmanship focused on metal stamping parts processing, hundreds of processing and production equipment, 20,000+ sets of customized stamping die production experience, monthly 100+ sets of mold processing capacity, 3 million punching times per day Production capacity, stamping accuracy can reach 0.01mm, 16 quality inspection layers are strictly controlled. It can quickly solve time-critical problems for you, solve stamping accuracy problems, and solve production quality problems. Choose, choose, rest assured!
