Zinc Die Casting Essentials. Also about versatility and durability, aluminum alloy as a material for the diecasting process is one of the top choices in the list. Many manufacturers prefer aluminum die casting for the fabrication of parts and items such as those used for golf clubs, lock housings, motorcycles and automotive, and home fixtures among others. The technologically advanced equipment that are used today for the zinc diecasting process make it more convenient to produce near perfect replicas of any metal parts. The precision in size, shape, and texture allows for efficient and economical mass manufacture of items and parts for the manufacturing sector. zinc as a material for die casting parts also allows for the output to be finished as the user may require . Among the finishing processes that could be done on a aluminum alloy diecast part include polishing, chrome or nickel plating, and powder or brass coating – the most common finishing is nickel plating which leaves the surface of the zinc die cast part a smooth and shiny.
A process of zinc alloy diecasting is similar to other material diecasting processes in that it uses a molten alloy that is pressure injected into die casting tooling. Die casting using aluminum alloy metal could either make use of the hot chamber method or the cold chamber method. In the hot chamber method, the zinc is melted and fed into the die cavity using a pneumatic piston or a hydraulic piston. While this method works well with aluminum alloy, this kind of method is not recommended for some materials like aluminum and those with aluminum components since these alloys can sweep with it some iron components of the molten pool. Lead-based alloys like tin and lead are best used for the hot chamber method. The cold chamber method, on the other hand, is also a good method to use for aluminum alloy castings. With this method, the casting material is melted in a separate heating chamber after which it is fed into an unheated injection cylinder that in turn feeds it into the die. As the molted alloy passes through several stages, the cold chamber method takes longer to complete, resulting in slower cycle times.
Zinc alloy is one of the most preferred materials in die casting. Aside from its versatility in use for both the hot chamber method and the cold chamber method, the properties of zinc lend itself best for use in the die casting process. In its melted form, the zinc alloy exhibits outstanding fluidity while its solid state offers high strength and hardness. Another advantage to zinc alloy die casted products is its excellent corrosion resistance and its capacity for high heat and electrical conductivity.
