Plastic mold steel is specifically designed to meet the stringent requirements of the plastic molding process, such as high wear resistance, corrosion resistance, polishability, and dimensional stability. Here are some common types of plastic mold steel and their applications:
1. P20 Steel
- Properties: Pre-hardened, good toughness, and excellent polishability.
- Applications: Widely used for injection molds, die casting dies, and extrusion dies.
2. H13 Steel
- Properties: High toughness, excellent heat resistance, and good wear resistance.
- Applications: Suitable for high-temperature applications, including die casting, extrusion, and plastic injection molds.
3. 420 Stainless Steel
- Properties: High corrosion resistance, good polishability, and moderate wear resistance.
- Applications: Used for molds requiring high surface finish and corrosion resistance, such as medical and food processing equipment.
4. S136 Steel
- Properties: High corrosion resistance, excellent polishability, and good wear resistance.
- Applications: Ideal for molds used in environments with high humidity or corrosive materials, such as medical devices and optical products.
5. 718H Steel
- Properties: Pre-hardened, good toughness, and excellent machinability.
- Applications: Commonly used for large plastic molds and die casting dies.
6. NAK80 Steel
- Properties: Pre-hardened, excellent polishability, and good machinability.
- Applications: Suitable for high-precision molds requiring a high surface finish, such as optical lenses and electronic components.
These steels are chosen based on their ability to withstand the high pressures and temperatures involved in the plastic molding process, ensuring the production of high-quality plastic products. If you have any specific applications or further questions, feel free to ask!
