Cold stamping process characteristics
Electric Steering Motor housing
The cold stamping molds we usually come into contact with are mainly stamping materials of iron, steel, copper, stainless steel plate steel, etc. Different materials, different strengths, different precisions, different main uses and characteristics;
Iron keys include: SECC; SPCC; SGCC; SPET (tinplate); SPHC; CRS, etc.
The key steel materials are: S50C, SK7, SK5, etc.;
The key materials of copper are: beryllium copper (red, yellow), tin bronze, CUC1100, etc.;
Aluminum profiles include: AL5052, O material, etc.;
The key of stainless steel is: SUS301, SUS304, SUS2D~SUS2B, etc.;

This cold stamping material has its unique characteristics and characteristics
- 1. Cold stamping material SECC: It is characterized by good anti-rust treatment effect, beautiful appearance design, certain environmental protection effect, and convenient processing. It is one of the most common stamping materials at this stage;
- 2. SPCC: Since there is no hot-dip galvanized layer on the surface, the proportion of anti-rust treatment SECC is not good, but this material has good coating processing performance and flexibility, and is very suitable for stamping products that must be painted;
- 3. SGCC It is a kind of flower board, its advantages are beautiful appearance design and good compressive strength, but this kind of stamping material is generally thicker, very suitable for some fixed basic versions and other commodities
- 4. Tinplate iron (SPTE), this kind of stamping material has a good improvement and heat dissipation effect, and is easy to process, but this material is generally very thin and is not suitable for making some common external parts, so common stamping parts are attached on plastic parts;
- 5. The surface of SPHC material is dark gray, which has the advantages of high compressive strength, good ductility, strong binding force of electroplating process, and convenient processing. It is generally used for some parts that often require thematic activities, but the disadvantage is that the friction performance is poor to prevent friction damage during movement;
- 6. S50CSK7SK5 These materials are relatively hard, and heat treatment can be carried out after the stamping product is completed. The heat treatment process has good wear resistance, and can be used as a component for the friction part of the product theme. Improve wear resistance;
- 7. Copper for stamping parts has the characteristics of soft material, strong electrical conductivity, strong heat dissipation effect, strong flexibility, and no corrosion, but the product cost is relatively high, and it is easy to cause safety risks such as extrusion during processing and manufacturing. Die marks, etc. ;
- 8. The aluminum profile of stainless steel stamping parts is characterized by soft touch, good flexibility, good adsorption effect and good heat dissipation effect. Unique aluminum profile processing technology, exquisite appearance, no corrosion, light material;
- 9. Stainless steel stamping material; the main features are anti-rust treatment and anti-oxidation, high material strength, good wear resistance, high ductility; generally used as kitchen supplies, medical supplies and other wear-resistant or high compressive strength products; disadvantages It is high price and cost, and the coefficient of processing difficulty is large;
