Shanghai Songjiang hardware stamping parts exporter, selected materials + raw materials imported and national standard original factory

The technicians of Shanghai Songjiang hardware stamping parts exporter have introduced that the surface and internal properties of stamping sheet materials have a great influence on the quality of stamping products. What are the requirements for stamping materials? Xiaoshuo collected some relevant information, and I will share it with you 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 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 uneven deformation will occur. Hardware, 15 years of ingenuity and focus on metal stamping parts processing, 20000+ sets of stamping die custom production experience, monthly 100+ sets of mold processing capacity, hundreds of precision processing production equipment, 3 million punches per day Sub-production capacity, the stamping accuracy can reach 0.01mm, the raw materials are imported and the national standard original factory, and 16 quality inspections are strictly controlled. It can quickly solve the time emergency problem, solve the stamping accuracy problem, and solve the production quality problem for you. Choose, choose rest assured!
