Different Types of Zinc Die Casting Parts. The zinc die casting process is one that has become extremely popular over the last decade, although it has been around for many years now. The reason for this is simple: the zinc die casting process offers a number of benefits. Moreover, the process can produce different types of zinc die cast parts, and just what these are we will be discussing in this article.
Basically, there are three zinc die casting methods, and they are die casting, sand casting, and gravity-fed casting. Die casting is probably the most popular and the oldest of all three methods. It is also the method that produces zinc die cast parts that have the highest tolerance and the most incredible, fine finish. The process mainly places pressure on the liquid zinc so that the die cast parts end up more detailed than other cast parts. Die casting is recommended for the production of small to medium zinc die cast parts. Sand casting, on the other hand, is recommended for the production of large zinc die cast parts that require coarser surfaces. Compared with die casting, the production costs (both pre and post) of sand casting are higher, but the tooling costs are lower. Finally, gravity-fed casting is considered as an intermediate option. Thus, it is recommended for the production of zinc die cast parts in all sizes. The polish or finish of zinc part die castings is as fine as that of the die casting process; the production costs are lower than those of the sand casting process; and the tooling costs are relatively affordable or reasonable.
