What is Die casting?
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 during the process. Most die castings are made from non-ferrous metals, specifically zinc, copper, aluminium, magnesium, lead, pewter, and tin-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 high-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.
Why we normally use Zinc alloy ?
Zinc alloy is an excellent material for 2D & 3D cubic designs that have empty spaces within; for miniature-sized designs or designs with mechanical functions such as moving and spinning badges. Because zinc alloy is more economical than brass material and it has wider application in various situations, it has become the top list material nominated by customers for manufacturing their badges and medallions. Miracle custom is proud of our exquisite quality for both die struck emblems and zinc alloy made pins and badges.
