• What are the surface treatment processes of metal stamping parts?
    • 2022-03-09

    1: Electroplating The process of attaching a metal film to the surface of metal by electrolysis to prevent corrosion A technology that can improve weldability, conductivity and beauty. Usually electroplated with gold, silver, nickel, zinc and tin. 2: Anodic oxidation It is mainly the anodizing of aluminum, which uses the electrochemical principle to generate a layer of alumina film on the surface ...

  • Requirements for bending parts in the processing of metal stamping parts
    • 2022-03-04

    The processing of metal stamping parts is the requirements for bending parts: 1. The shape of bending parts shall be symmetrical as far as possible, and the bending radius shall not be less than the minimum bending radius allowed by the material. 2. The curved edge is too short and difficult to form, so make the straight part of the curved edge H > 2 δ。 If h is required to be very short, approp...

  • What's the difference between national standard and non standard stamping parts?
    • 2022-02-23

    The quality standards of stamping parts are divided into national standard and non-standard. The following are different concepts about national standard and non-standard: National standard: refers to the standard approved and issued by the national standardization authority, which is of great significance to the national economic and Technological Development and is unified throughout the country...

  • Material selection of stamping parts
    • 2022-02-08

    The three most important steps in a stamping factory are shearing, punching / cutting and folding. Stamping parts are sometimes used as metal pulling. The word comes from English platemetal. Generally, some metal sheets are pressed by hand or die to produce plastic deformation to form the desired shape and size, and more complex parts can be formed by welding or a small amount of mechanical proces...

  • How to solve the burr problem of stamping parts
    • 2022-01-15

    Metal processing plants often encounter burrs in metal stamping parts when producing metal stamping products. There are tools to remove the burr of metal stamping parts: 1. Hole: use a chamfering knife or the front end of a larger diameter drill bit 2. Edge: use file, oilstone, sandpaper, grindstone, 3. Welding slag: vibration slag removal tools can also remove brittle burrs 4. Outer diameter: gui...

  • Sampling inspection method for metal stamping parts
    • 2022-01-04

    Hardware stamping factory has strict inspection standards, which are divided into sampling inspection and all inspection. Sampling inspection, also known as sampling inspection, is a statistical method and theory to randomly select a small number of products (samples) from a batch of products for inspection, so as to judge whether the batch of products are qualified or not. It is different from co...

  • Stamping process operation specification
    • 2021-12-30

    Stamping process and its characteristics stamping is a pressure processing method that uses the die installed on the press to exert pressure on the material at room temperature to produce separation or plastic deformation, so as to obtain the required parts. Stamping is usually cold deformation processing of materials at room temperature, and mainly uses sheet metal to process the required parts, ...
