1. Hot Chamber
2. Cold Chamber 1. Hot Chamber Hot chamber die casting is one of two major methods in manufacturing process of die casting. This section will mainly discuss specific details of hot chamber process and contrast the differences among hot chamber die casting and cold chamber die casting, which is other branch of die casting manufacture. A comparable characteristic of also die casting method is use of high pressure to force molten metal during a mold call a die. Several of better qualities of castings manufactured through die casting, (for example great surface detail), can credit to use of pressure to make sure the flow of metal through die. In hot chamber die casting manufacture, supply of molten metal is attach to die casting machine and is an integral part of casting tools for this manufacturing process. 2. Cold Chamber Cold chamber die casting is a permanent mold metal casting method. Reusable mold, gating system and all, is working. It is mainly possible machined exactly from two steel blocks. Large robust machines are use to use great clamping force required to hold two halves of mold jointly next to the tremendous pressures exerted during manufacturing process.
