Zinc Parts Types. No doubt zinc is the best metal in die casting. Zinc is the easiest metal to cast because of its resistance to temperature and impact. Zinc parts are durable and have wider variety of applications than others, which are made of aluminum, magnesium, lead and tin. For several years, Zinc die casting has been the most popular casting process. This is because a number benefits are being offered by zinc die casting process.
It produces several zinc die casting parts. The best method that creates zinc parts with most fine finish and highest tolerance is die casting. In this process the zinc is subjected to pressure to make the die cast end up with more detailed parts than other parts of the cast. The zinc casting is highly suggested for the manufacturing of medium zinc parts.
The other popular method is sand casting that is suggested for the manufacturing of large zinc parts that require coarser surfaces. Sand casting is much more expensive than die casting. To produce all sizes of cast parts, the gravity-fed process is used. Comparing the three processes die casting heeds a fine finish and the production cost is much lower than with sand casting.
Die casting has reasonable and affordable tooling cost and most electrical and electronic equipment are made of zinc. The strength and hardness of zinc parts are not always present in parts that are plastic molded, sand cast, permanent mold cast, stamped, forge and screw machined.
