Know the Functions and Procedures of Die Casting

Die casting is one of the quickest forming processes and an economical one. The benefits of this production process are that hundreds of automotive plastic part can be produced that to very quickly with the use of just one mold. Every component produced has a uniform quality and includes low unit costs.

Functionality and Procedures

You will find two different ways of manufacturing components in die casting: hot chamber and cold chamber die casting. In both the manufacturing processes, before the casting process, the mold is sprayed with a release agent by the automotive plastic parts manufacturer. Into the mold cavity, the melt is not poured directly, but first, it is filled into the casting chamber of the die casting machine. From there, by a piston (the so-called casting set) through one or more channels the alloy is pressed into the mold. In the structure of the casting chamber, you will find the difference between the two processes.

Cold Chamber Die Casting Method

The design of Cold chamber dies casting machines are in such a way that the casting set is situated outside the melt. The alloy is filled into the casting chamber to produce a component and then it is pressed into the die casting mold with the help of channels. For materials with a higher melting point, this is process quite suitable. These include aluminum and copper. Every component produced has a uniform quality and includes low unit costs.

The component solidifies under strong pressure after the alloy has been pressed into the mold in both processes, where the latches of the mold can be opened.

Hot Chamber Die Casting Method

One characteristic feature of hot chamber dies casting machines is that the casting chamber is in continuous contact with the liquid alloy. For materials with a higher melting point, this is process quite suitable. Into the casting chamber, the melt passes through a valve, whereby the piston at high speed is pressed into the closed die casting mold. For alloys that have a low melting point, such as zinc, lead or tin automotive plastic parts China process is used.
