Die casting is a manufacturing process for producing metal parts by forcing molten metal under high pressure into a die cavity. Generally speaking, these die or mold cavities are created with hardened tool steel that have been previously machined to the net shape or near net shape of the die cast parts. This process allows products to be made with high degree of accuracy and repeatibility. The die casting process also produce fine details such as textured surfaces or names without requiring further processing.
The ability of producing high detailed and high accuracy parts make die casting a suitable choice for mass produced product. The moment you wake up you are surrounded products that are produced by the die casting process. When you turn the faucet, you open the door knob, when you drive your car, almost every product or part of the product you use in your daily life is produced using this process.
The die casting process usually produce parts using primarily non-ferrous metals, such as zinc, copper, aluminum and magnesium. Over the years, many different alloys have been developed to meet certain type of needs and requirements of each application.
Type of die casting processes
The die casting process can be further divided into two different categories:
- Hot Chamber Die Casting
- Cold Chamber Die Casting
