A hot chamber die-casting machine refers to a die-casting machine in which the injection chamber and injection punch are immersed in molten metal, and the injection chamber is connected to the gate of the die-casting mold through a gooseneck tube. Suitable for die-casting low melting point non-ferrous alloy parts such as zinc and lead, it can be widely used in industrial sectors such as automotive, motorcycle parts, instruments and meters, daily hardware, household appliances, etc.
The difference between cold chamber die casting machine and hot chamber die casting machine:
Die casting is a metal mold pressure casting process carried out on a die casting machine, which is currently the most efficient casting process in production. Die casting machines are divided into two categories: hot chamber die casting machines and cold chamber die casting machines. Cold chamber die-casting machines are divided into two types based on their chamber structure and layout: horizontal die-casting machines and vertical die-casting machines (including fully vertical die-casting machines).
The hot press chamber die-casting machine (referred to as hot air die-casting machine) is immersed in the liquid metal of the insulation melting crucible, and the injection parts are not directly connected to the machine base, but are installed on the crucible. The advantages of this die-casting machine are simple production process and high efficiency; Low metal consumption and stable process. But the pressure chamber and injection punch are immersed in liquid metal for a long time, which affects their service life and easily increases the iron content of the alloy. Hot press chamber die-casting machines are currently mostly used for the production of castings of low melting point materials such as zinc alloys and magnesium alloys.
The pressure chamber of the cold chamber die-casting machine is separated from the insulation furnace. During die-casting, liquid metal is taken out of the insulation furnace and poured into the pressure chamber for die-casting. The aluminum alloy die-casting parts widely used today can only be produced on cold chamber die-casting machines due to their high melting point.
