How does extrusion technology apply to cold pier processing
2025-08-20
How to apply extrusion technology to cold pier processing has been a long-standing problem. The following Xiaobian is about the principle between them, hoping to help you.
Generally, the forming of bolt head is plastic by cold heading processing. The cutting and extrusion forming process has more advantages than the swelling process. The size of the blank must be paid attention to, the shape of the blank before extrusion should be determined according to the situation of the parts, and the shape of the blank which is conducive to the flow of materials should be used. If the blank size is too large, that is, the cutting and extrusion margin is too large, the required cutting and extrusion force is larger, which is easy to reduce the life of the cutting and extrusion die, increase the possibility of mold accidental damage, and consume raw materials. The margin of cutting and squeezing is too small, the corners of the parts are easy to fall off after cutting and squeezing, the shape is incomplete, and the appearance quality is not satisfactory.
Above is the application of extrusion technology in cold pier processing.
