Die casting machine types are defined with following:

Die casting machine type 1: hot chamber die casting machine

The hot chamber die casting machine has simple structure, convenient operation and easy realization of automatic production; no casting process is required, the process is simple, the production efficiency is high; the heat loss is small, the metal loss is small; the molten metal is always in the closed channel, and the oxidation inclusion is not easily entangled. The molten metal entering the cavity is clean, the casting quality is good; the injection pressure is small, and there is no pressurized section in the injection process; the hot working parts such as the pressure chamber, the punch, the gooseneck, and the nozzle have a short life and are inconvenient to replace.

In the current die-casting production, hot chamber machines usually die-cast and produce low-melting alloys such as zinc, tin and lead, and small-sized, thin-walled magnesium alloy die-casting parts. Most of the clamping force is less than 160T, and less than 400T. Magnesium alloys are produced by hot chambers and cold chambers due to their molding characteristics. The hot chamber machines for producing magnesium alloys usually have a clamping force of less than 650T.

Die casting machine type 2: horizontal cold chamber die casting machine

The cold chamber die-casting machine has a comprehensive specification and model. It has a wide adaptability to product size and alloy type, simple production and operation, high production efficiency, and can be automated with online peripheral equipment. The segmentation control and adjustment of the injection stroke are easy to implement. The satisfaction of different requirements of the die casting process is good. The disadvantage is that the metal liquid heat loss during the injection process is large, the metal liquid is in contact with the air, and it is easy to be entangled with the oxidized inclusions and air, and a special process is required for the high density or the product requiring heat treatment.

At present, horizontal cold chamber die casting machines are mainly used for the production of non-ferrous alloys such as aluminum, magnesium and copper, and there are few applications for ferrous metal die casting. The cold chamber die casting machine has a clamping force of several tens of tons to several thousand tons. The largest cold chamber die casting machine is the 5500T die casting machine produced by Miller Wagner.

Die casting machine type 3: vertical die casting machine

The vertical die casting machine has less metal entrapment during the hydraulic injection process; it is convenient for the central casting system setting; maintenance and operation troubles, cutting and cake launching procedures in the production process, low production efficiency; mainly small and medium-sized machines, production The amount used in the process is relatively small; currently the vertical die casting machine is mainly used for die casting production of special products such as motor rotors. With the continuous improvement of the injection performance of the cold chamber die casting machine in the bedroom, in order to improve the production efficiency, the micro-motor rotor has been increasingly produced by the horizontal cold chamber die-casting machine.
