Cemented carbide moulds are more than ten times or even dozens of times the life of steel moulds. Cemented carbide moulds are only high hardness, high strength, corrosion resistance, high temperature resistance and small expansion coefficient.
YG15, YG20, YG20C, YG25 and HU20, HU222, HWN1 (non-magnetic alloy moulds), etc. The use of primary carbide materials, low-pressure sintering and other special processes, toughness will be better than conventional production, life will also be increased by 3-5 times.
Carbide moulds are often available: cold heading dies, cold punching dies, wire drawing dies, hexagonal dies, spiral dies, etc.
A, the advantages of carbide moulds
Cemented carbide die is a kind of metal powder and a certain amount of corrosion agent with high temperature, high pressure chemical reaction way refined block carbide material, can be in high temperature, high pressure, strong corrosion environment long-term stable work. Its main advantages include:
1. High hardness and strength: The hardness of carbide moulds can reach 1500-2200 HV, which is many times higher than the hardness of traditional steel moulds, so it has significant advantages in terms of wear resistance and durability.
2. High wear resistance: Cemented carbide has high hardness, high toughness and high rigidity, which greatly improves the wear resistance of moulds and can maintain excellent surface quality and process accuracy for a long time.
3. Strong corrosion resistance: Cemented carbide moulds are highly resistant to corrosion and can work stably under the environment of strong acid, strong alkali, high salt and other corrosive media, without surface corrosion and flaking.
4. High precision: carbide product moulds have good material uniformity, high density, not easy to oxidation and deformation, high mould size precision and complex shape.
Second, the scope of application of carbide moulds
The application range of carbide product moulds is very wide, mainly can be applied to the following fields:
1. Metal processing: carbide moulds can be made into various shapes of cold heading dies, cold punching dies, extrusion dies, drawing dies, extrusion dies, drills, reamers, blades, cutting knives, resharpening tools, etc. The processing efficiency of high hardness materials such as tungsten steel, high-speed steel and carbide is significantly improved.
2. Plastic processing: carbide moulds can also be used to make various plastic moulds for injection, extrusion and blow moulding, such as bottle caps, juice bottles, plastic chairs, plastic test tubes, plastic clips, etc.
3. Petroleum, chemical industry: Cemented carbide moulds can also be used for valves, spools, pump bodies, pump leaves, clamps, etc. in petroleum and chemical industries.
