Lead Die Casting Process
Lead is a popular material to use for applications where high density and tight dimensional accuracy is required. An added benefit of lead die casts are they are not prone to corrosion. Lead in typically cast in hot chamber machines, also known as gooseneck machines, where a pool of molten metal to feed the die. In hot chamber die cast, a piston is retracted, allowing molten metal to fill the gooseneck. The piston then pushes the molten into the die. A distinct advantage of hot chamber machines is the ability to liquefy the metal in the casting machine. In addition, hot chamber machines have fast cycle times. However, hot chamber machines are limited to metals with low melting temperatures such as lead, zinc and tin based alloys.

In addition to using high pressure hot chamber die casting for lead, four slide hot chamber die casting can be used for lead products. Four slide hot chamber die casting (often referred to as Miniature Die Casting) is the process in which the injection system is partially immersed in of bath of molten metal contained in a furnace; the furnace is integral to the machine. The main components of the injection system are: Injection Cylinder, Plunger, Piston, Gooseneck and Nozzle. At the beginning of the cycle the piston moves upwards which allows molten metal to be drawn into the gooseneck through a port. Next the dies closes, sealing the cavities of the die. The design of the dies for the multi-slide die casting process is what makes multi-slide die casting machines unique from traditional die casting machines. In a traditional die casting process, only one half of the die moves when closing the die; in the multi-slide process, as many as eight sections of the die (but more typically two to four) move together to close the die. Now that the die is closed the plunger moves downwards, it seals the port and forces the molten metal through the gooseneck and nozzle into the die filling the cavities with molten metal. Once the metal solidifies, the cast is ejected and the process repeats.
