What are the performance model requirements for mold 3D printing?

Used for injection molding, blow molding, extrusion, die casting or forging, melting, stamping, stretching, and other molds and tools. In short, molds are tools that shape products. The tool consists of different parts, and different molds consist of different parts. It mainly processes the shape of the product by changing the physical state of the molding material. We often use molds to make some hand boards.
1、 Abrasion resistance
When the steel billet undergoes plastic deformation in the mold cavity, the steel billet flows and slides along the mold cavity surface, causing severe friction between the mold cavity surface and the steel billet, leading to mold failure due to wear. Therefore, the wear resistance of materials is one of the basic mold important properties. Hardness is the main factor affecting wear resistance.
2、 Strong toughness
The working conditions of 3D printing models are mostly poor, and some often bear large impact loads, leading to brittle fracture. In order to prevent sudden brittle fracture of mold parts, molds should have high strength and toughness. The toughness of the mold mainly depends on the carbon content, grain size, and microstructure of the material.
3、 Fatigue fracture performance
During 3D printing of molds, fatigue fracture often occurs under long-term cyclic stress. Its forms include low energy multi impact fatigue fracture, tensile fatigue fracture, contact fatigue fracture, and bending fatigue fracture.
4、 High temperature performance
When the working temperature of the mold is high, the hardness and strength decrease, leading to early wear or plastic deformation and failure of the mold. Therefore, the mold material should have a high tempering resistance stability to ensure that the mold has a high hardness and strength at operating temperature.
