In the high-pressure die casting process, the liquefied metal is injected at high pressure and high speed in the mold. With horizontal high-pressure, the equipment makes sure that the die closes well. It can be rated by how much closing force will be applied.

It depends on the metal used; the injection unit is then filled with either cold or hot chamber. The hot chamber die castings hold the metal in the equipment itself, then attract into the chamber and get into the mold using the injection gun. The equipment parts mentioned are in contact with the liquefied metal.

The cold chamber process the material by melting the metal first in a separate furnace and then into the holding furnace. It is then poured in a shot sleeve and injected in the mold.

Benefits of the High Pressure Die Casting Process

This type of die casting can provide huge light-alloy components, in higher volumes and speeds. The equipment offers light-alloy components with high precision, excellent uniformity, maximum mechanical properties, and an impressive surface finish.

The high-pressure process can likewise generate parts with thin walls. The co-cast components with various types of inserts like liners and screws become an essential part of the product itself. Other advantages of this process include the following:

Die Casting Process

High-Speed Production

This type of casting can produce complex shapes within closer tolerance as compared to other mass production processes. It does not require machining, and lots of similar casts can be generated before adding the needed tooling.

 

Dimensional Stability and Accuracy

The casting generates parts that are dimensionally stable and tough, as it maintains close tolerances. These components are likewise heat resistant.

Weight and Strength

As compared to plastic injection moldings, die-cast parts are durable. Thin wall castings are lighter and robust compared to other casting methods. Also, since diecast does not have separate parts fastened or welded together.

Simplified Assembly

This process provides essential fastening elements like studs and bosses. Holes can be bored and made by drilling the sizes or casting the external threads.

Different Finishing Methods

The parts produced using the die-cast process can be generated with textured or smooth surfaces, and they can be plated easily or finished with less surface preparation.

As compared to other methods like sand casting, die casting require less machining. It can be done with thinner walls. The labor cost is less.
