Metal stamping parts processing, the hole is abnormal, and analysis of the reason is?1

Metal stamping parts processing of related knowledge of traditional metal products, also known as hardware. Refers to the iron, steel, aluminum and other metal after forging, rolling, cutting, and so on physical processing and manufacturing of all kinds of metal components. For example, hardware tools, metal parts, daily hardware stamping metal stamping parts processing relevant knowledge of the traditional hardware products, also known as the 'hardware'. Refers to the iron, steel, aluminum and other metal after forging, rolling, cutting, and so on physical processing and manufacturing of all kinds of metal components. For example, hardware tools, metal parts, daily hardware, architectural hardware, decoration hardware, security products and so on. Mechanical hardware category of hardware, it is to discuss issues of stamping parts processing. Stamping pieces of metal stamping processing, that is, by the press and the mold to exert external forces such as sheet, strip, pipe and profile, make its produce plastic deformation or separation, thus to obtain the required shape and size of the workpiece, Stamping parts) The forming method. Metal stamping parts processing has the following advantages: 1, precision metal stamping parts of the workpiece precision, and thin, light, well. 2, the hardness of metal stamping parts, is not easy to damage. 3, metal stamping die to ensure the workpiece size and shape, precision metal stamping parts produced with high efficiency.
