Die casting (also known as High Pressure Die Casting) is a metal casting process that is characterized by forcing molten metal under high pressure into a mold cavity. The mold cavity is created using two hardened tool-steel dies which have been machined into shape and work similarly to an injection mold. Our die castings are made from non-ferrous metals, specifically zinc, aluminum, and magnesium based alloys. Depending on the type of metal being cast, a hot- or cold-chamber machine is used.
The casting equipment and the metal dies represent large capital costs and this tends to limit the process to higher volume production. Manufacture of parts using die casting is relatively simple, involving only four main steps, which keeps the incremental cost per item low. It is especially suited for a large quantity of small to medium sized castings, which is why die casting produces more castings than any other casting process. Die castings are characterized by a very good surface finish (by casting standards) and dimensional consistency.
If you're looking for the most economical, efficient technology to produce your design in a durable and rigid metal form, the high pressure die casting process may be the solution. Parts can range in size from as small as 1" x 1" up to 24" x 24". It provides a broader range of shapes and components than many other manufacturing technique. In addition, the high pressure die casting process provides a high degree of dimensional accuracy and offers:
