Production process

(1) Sheet metal: Definition: A comprehensive cold working process for metal sheets, through blanking, bending, forming, welding, surface treatment and other operations on the plate, to produce parts or products with specific shapes and functions Process: blanking - bending - forming - welding - surface treatment
(2) Stamping: Definition: A machining method in which a mold mounted on a press is used to apply pressure to a material at room temperature to produce separation or plastic deformation to obtain a part of the desired shape and size. Process: punching - bending - stretching - forming

  • Progressive stamping
  • Single process stamping
  • Deep drawing stamping
  • Powder coating
  • Anodizing
  • Plating
  • Polishing
  • Electrophoresis
  • Sonicleaning
  • Etching

Production Materials

(1) Carbon steel: It has high strength, toughness and processability, and is one of the most commonly used materials in sheet metal stamping. Q235 steel has moderate strength and good stamping properties, and is widely used in sheet metal parts with various general requirements.
(2) Stainless steel: It has excellent corrosion resistance, oxidation resistance and good appearance quality. The common 304 stainless steel has good comprehensive properties and is suitable for sheet metal parts in food processing, decoration and other fields; 316 stainless steel is more resistant to corrosion, making it especially suitable for parts used in harsh environments, such as sheet metal components in chemical equipment.
(3) Aluminum alloy: It has the advantages of low density, high specific strength, good corrosion resistance and easy processing. 5052 aluminum alloy has good formability and corrosion resistance, and is commonly used in sheet metal parts with weight requirements such as automotive parts and electronic equipment housings.
(4) Copper and copper alloys: It has good electrical conductivity, thermal conductivity, corrosion resistance and ductility. Brass (copper-zinc alloy) and bronze (copper-tin alloy, etc.) have good mechanical properties and corrosion resistance, and can be used to manufacture some sheet metal parts with high requirements.
