Precision plastic molds meet working conditions:
1. Wear resistance of precision plastic mold: Hardness is the main factor affecting wear resistance. In addition, the wear resistance is also related to the type, quantity, shape, size and distribution of carbides in the material.
2. The toughness of precision plastic mold: The toughness of precision plastic mold mainly depends on the carbon content, grain size and microstructure of the material.
3, fatigue fracture performance: the fatigue fracture properties of precision plastic molds mainly depends on its strength, toughness, hardness, and the content of inclusions in the material.
4. High temperature performance: The precision plastic mold material should have high anti-tempering stability to ensure the mold has high hardness and strength at working temperature.
5, resistance to cold and heat fatigue performance: hot and cold fatigue is one of the main forms of hot mold failure, such molds should have high resistance to cold and heat fatigue.
6. Corrosion resistance: Some precision plastic molds such as plastic molds work, because of the presence of chlorine, fluorine and other elements in the plastic, after the heat, the HCI, HF and other strong aggressive gases are resolved, eroding the surface of the mold cavity and increasing its Surface roughness, which aggravates wear and tear.
