Wear resistance: When the blank plastically degenerates in the mold cavity, it flows and slides along the cavity surface, causing severe friction between the cavity surface and the blank, causing the mold to fail due to wear.
Strong toughness: Most of the working conditions of molds are not good, and some often bear large impact loads, resulting in brittle fracture. In order to prevent the mold parts from suddenly breaking during operation, the mold parts must have high strength and toughness. The toughness of mold parts mainly depends on the carbon content, grain size and organizational state of the material.
Corrosion resistance: When the plastic mold is working, due to the presence of chlorine, fluorine and other elements in the plastic, highly corrosive gases such as HCL and HF are decomposed after heating, which erodes the surface of the mold cavity, increases its surface roughness, and aggravates wear and failure.
Fatigue fracture resistance
Anti-fatigue fracture performance is a property that all new mold parts have now, because in the high-intensity production process, mold parts are prone to fatigue fracture under long-term force, so mold parts with anti-fatigue fracture performance are now It is very important, and the fatigue fracture resistance of mold parts depends on its strength, toughness, hardness and the process and materials used to make the mold parts.
High temperature resistance
Because molds are constantly entering and exiting the production line during the production process, high temperature work will weaken the hardness and strength of mold parts. Therefore, molds with tempering resistance stability Accessories can ensure the stability of the production process and the high quality of the product in high temperature environments.
