  • Do you know how to deal with the crack of the drawing stamping parts?
    • 2022-05-24

    During the production and processing of stretch stamping parts, there will be tension cracks. Do you know why tension cracks occur? How to deal with this situation? When the tensile stress on the cylinder wall exceeds the strength limit of the material during the processing of tensile stamping parts, the product will crack, and the crack usually appears at the cylinder wall slightly above the fill...

  • What are the differences between sheet metal processing and machining?
    • 2022-04-15

    Usually, sheet metal is the material for the plate type, which is generally made into the specified shape and operated by the plate shearing machine or bending machine, while the machining is more complex. The material is massive, not simply bent and deformed, but cut, etc. the equipment generally uses lathes, grinding machines, etc

  • Surface treatment of metal stamping parts
    • 2022-04-08

    Why is the surface quality of metal stamping parts poor? There are many reasons for the surface quality problems of stamping parts. For example, the surface quality of coil, sheet and die will affect the quality of stamping parts.
