Die Casting is a metal mold consisting of several parts whose material is made of steel (Hot Working Steel). The basic properties of Die Casting are in the form of heat yield strength, resistance to tempering process (tamper resistant), coefficient of heat (thermal expansion coefficient), thermal conductivity (thermal conductivity and ductility).
The use of this method is suitable for the manufacture of thin-walled objects both for use in households, motor vehicles, small appliances, and electric motors, which means most likely made by the die casting industry. can be avoided. Die casting provides several technical and economic benefits, not only due to its high manufacturing power, but also the very short processing time between raw materials and products. Castings are generally made of non-ferrous metals, especially zinc, aluminum, magnesium, copper, lead, tin and other solvents. Die Casting is suitable for a variety of sizes whether small, medium, or large. The level of flexibility places this process with the highest number of users in the metalworking industry.
The Benefits of Die Casting
- Produces high flow rate
- Can make thin-walled and precision sized objects
- Excessive size can be avoided
- Good surface quality
- Excessive size can be avoided
- Very short processing time
Die Casting Disadvantages
- Machine prices are more expensive
- Higher operational costs
- More material is wasted due to biscuits and thus more second-class material (return material)
In short, the process of idea casting is that the material is melted first and then injected into a mold with high pressure and speed, so it needs equipment with special materials such as tools for compressing dies which must also be made of hardened tool steel. This die casting process cannot use dies made of sand, because it will fall off when it is under pressure and a fast flow of material. The die-casting process always follows the sequence of the dies closing and being locked, the material is injected into the dies and held for a while, the dies are opened, the ejector works to remove the product from the dies.
