1. Stamped parts are made by applying external forces to sheets, plates, strips, tubes and profiles by means of a press and a die to produce a plastic deformation or separation to obtain a workpiece of the required shape and size.
2. Stamped parts are mainly made of metal or non-metal material sheets, which are pressed and shaped with the help of punching machines and stamping dies.
3. Because stamped parts are pressed under punching machines at the base of not too much material cost, it’s well-known with light weight and good stiffness. What’s more, the internal structure of the metal will be improved after the plastic deformation of the sheet, which will contribute to increase the strength of the stamped part.
4. Stamping parts have high dimensional accuracy, uniform size and good interchangeability. It can meet general assembly and requirements on application without further mechanical processing.
5. Due to the surface of the material is not damaged in the stamping process, metal stamping products usually has a good surface quality, smooth and beautiful appearance, which can provide convenient conditions for surface painting, electroplating, phosphating and other surface treatment.
6. Commonly stamped metal parts include metal clips, poppers, terminals, contacts, brackets, base plates, drawn parts, connectors, etc.
7. The usual materials for stamped parts are as below.
·Ordinary carbon steel plate, such as Q195, Q235, etc.
·High quality carbon structural steel plate, the chemical composition and mechanical properties of this kind are guaranteed, the carbon steel to low carbon steel use more, commonly used 08, 08F, 10, 20, etc.
·Electrical silicon steel plate, such as DT1, DT2.
·Stainless steel plate, such as 1Cr18Ni9Ti, 1Cr13, etc., for the manufacture of corrosion and rust prevention requirements of the parts.
·Low alloy structural steel plates, such as Q345 (16Mn), Q295 (09Mn2), are commonly used to manufacture important stamping parts with strength requirements.
·Copper and copper alloys (such as brass), such as T1, T2, H62, H68, etc., its plasticity, conductivity and thermal conductivity are very good.
·Aluminium and aluminium alloys, commonly used grades are L2, L3, LF21, LY12, etc., with good plasticity, small deformation resistance and light
