Casting mold refers to the model of obtaining qualified parts, common manual modeling, common wood model, plastic model, mechanical modeling and multi-purpose metal model. Then how do we choose casting mold material? Next, the small series of Shenzhen GuoLan Plastic Mould Co., Ltd. Let us talk about the things you need to pay attention to when choosing casting mold materials.
Selection of casting mold materials:
1.Production batch: When the production quantity of stamping parts is large, the material of the punch and die of the working parts of the mold should be selected with high quality and good wear resistance. The other process structural parts of the mold and the part materials of the auxiliary structural part are also correspondingly increased. When the batch size is not large, the material performance requirements should be appropriately relaxed to reduce the cost.
2.Performance of stamped materials and conditions for use of mold parts
When the material to be stamped is hard or the deformation resistance is large, the convex and concave molds of the die should be selected from materials with good wear resistance and high strength. When drawing stainless steel, an aluminum bronze die can be used because it has good anti-adhesion. The guide bush guide sleeve requires wear resistance and good toughness, so the surface of low carbon steel is often carburized and quenched.
3.material properties should consider the hot and cold processing properties of the material and the existing conditions of the factory.
4.Use micro-deformed die steel to reduce machining costs.
For molds with special requirements, mold steel with special properties should be developed and applied.
5.The choice of mold materials should be determined according to the use conditions of the mold parts. Under the premise of satisfying the main conditions, low-cost materials should be used to reduce costs.
