cnc mold machining company believes that the mold industry produces various molds and tools for injection molding, blow molding, extrusion, die casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to make shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. cnc mold machining company tell us about the following requirements:

　　1. cnc mold machining company anti-cold and heat fatigue

　　Some molds are in the state of repeated heating and cooling during the working process, so that the surface of the cavity is subjected to tensile stress, causing surface cracking and peeling, increasing friction, hindering plastic deformation, reducing dimensional accuracy, and leading to failures in the mold.

　　2. Strong toughness

　　The working conditions of cnc mold machining company parts are mostly very harsh, and some often bear large impact loads, resulting in brittle fracture.

　　3. cnc mold machining company high temperature resistance

　　When the working temperature of the mold is high, the hardness and strength decrease, resulting in premature wear or plastic deformation of the mold. Therefore, the mold material should have high tempering resistance to ensure that the mold has high hardness and strength at working temperature.

　　4. Corrosion resistance

　　Some molds, such as plastic molds, are working, due to the presence of chlorine, fluorine and other elements in the plastic, after heating, they decompose and decompose strong corrosive gases such as HCl and HF, which erode the surface of the mold cavity, increase surface roughness and aggravate wear and tear failure.

　　5. Fatigue fracture performance

　　During the working process of cnc mold machining company parts, fatigue fracture is often caused by the long-term action of cyclic stress.
