Pressure die castings
Die casting is a metal casting process in which molten metal is forced under high pressure into a mold cavity. The mold cavity is made up of two hardened tool steel dies.
A characteristic feature of this casting technology are very high speeds and pressures not found in other casting technologies. Die-castings ensure high accuracy, dimensional stability, high surface quality and shape mapping.
The use of this technology ensures high metal yield. Due to the fine-grained structure, good mechanical, physical and chemical properties of castings are obtained.
Most of the die-castings are made of non-ferrous metals. Depending on the type of metal used, a cold – or hot-chamber machine is used.
What raw materials are used for casting?
- aluminum
- magnesium
- zinc
- brass
- copper
Aluminum die casting – the most common form of pressure die casting
What are the advantages of such production?
- a manufacturing process that allows to create a wide range of sizes and shapes;
- provides integral fasteners for further parts of the project;
- possibility of using CNC machining for further refinement;
- aluminum die-cast parts are strong and have a long service life;
- provides the ability to obtain complex shapes with greater dimensional accuracy and stability than those resulting from other mass production processes;
- parts can be produced with smooth or textured surfaces
- die-cast aluminum parts can be covered with protective coatings using technologies such as anodizing or powder coating and painted with minimal surface preparation.
Applications of aluminum castings in production
Modern production lines are full of mechanical components manufactured in various technologies, very often also by casting aluminum. It is widely used, among others in industries such as lighting, automation and robotics, and automotive. EURO METRICS has an extensive network of suppliers, advanced tools for quality control, production and delivery management, as well as experience in the implementation of projects for the largest European producers.
