What is Die-Cast

Die casting serves various purposes, such as manufacturing components for the automotive industry, producing decorative hardware, and creating numerous small components. It is worth noting that die-cast parts are extensively utilized in various products, often without people realizing that they are made from die-cast metal. Finished products like locks and gears are examples of commonly found items made through this process.

While cast aluminum involves the use of molten aluminum in a casting process to create aluminum components, die cast is a casting method that utilizes high-pressure die casting with raw materials. The main distinction between the two lies in the material used for casting the products.

The process is referred to as die casting because it involves the use of dies. These dies are steel molds that are primarily created through CNC machining. The liquid metal is injected into these molds, which consist of two halves: the fixed half, which remains stationary and is connected to the casting machine, and the ejector half, which is movable.

To manufacture light alloy castings, three commonly used technologies are high pressure die casting, gravity die casting, and low pressure die casting. These three methods enable the production of permanent castings, with gravity and low pressure also capable of supporting semi-permanent casting processes.

The two primary types of die casting processes are hot-chamber and cold-chamber die casting. Additional variations of these two types include low-pressure die casting and vacuum die casting.
