Zinc die casting & zinc die casting china
Zinc die casting is considered to be one of the most easily die cast metals. It is highly ductile, has high impact strength and minimizes die wear. For these and other reasons, zinc is a very popular die casting material. Understanding zinc’s popularity as a die casting material first requires an understanding of the die casting process. Let’s review that process quickly. Die Casting is the process by which molten metals are forced into a die in order to give them shapes. Dies are specially-designed cavities that are designed to create specific metal products. The process begins when a metal is heated until it becomes molten. Then, depending on the die casting method, the molten material is either directly drawn into the casting mechanism or is transported into it by other equipment. After that point, the molten metal is forced into the die cavity by a piston. It becomes pressurized within the cavity, which causes it to closely form around the contours of the die, causing it to take the shape of the die. At the end of the process, the metal is allowed to cool and harden, after which point it is ejected from the die and sent for additional processing if necessary.
It’s clear why zinc would be suitable for this process. Zinc’s melting point is substantially lower than magnesium and aluminum, two other popular casting materials. This means that it requires less energy to melt zinc, and it is formed more easily than several other alternative materials. Zinc is also easily plated, which means that cast zinc products can be subject to a wide variety of finishing processes, which are used to increase the performance of finished cast products. Zinc is also a highly economical material to use in the creation of small parts. Because of its favorable physical properties, zinc is one of the most popular die casting materials.
