What Is Die Casting?

Since the 19th century, the field of die casting has made a lot of progress. In this article, we are going to talk about the basics and different materials and processes of die casting. According to experts, if you want to create processes, this field is your most economical choice. With just one mold, you can produce thousands of castings. Moreover, the quality of the components will be the same and the cost will be very low. Let’s find out more.

Definition

Basically, this automated casting process involves pressing the liquid melt into a mold at extremely high pressure and speed. The pressure is between 150 and 1200 bar, and the speed is as high as 540 km/h. Generally, this process uses alloys with a very low point of melting.

In most cases, this process is an ideal choice for the mass production of a wide range of components. Moreover, this process makes use of permanent molds.

Molds

As for as molds are concerned, they are made of high-quality steel. The two halves create a cavity that holds the liquid melt. These two parts are fixed on a machine plate. High pressure is applied to the mold.

Apart from this, the die is cooled down in order to give the desired shape to the melt. It takes a lot of money and time to produce the mold. But the good news is that you can make millions of castings once the mold is ready.

Procedures and functionality

When it comes to die casting, components are manufactured using two different methods: cold chamber and hot chamber die casting. Regardless of the manufacturing process, a special release agent is prepared before the casting process. This is to make sure that the cast part is removed without any problem.

However, they don’t put the melt directly into the cavity. Instead, it is put into the casting chamber and then the alloy is forced into the mold using a strong piston.

Hot Chamber Method

One of the primary features of this process is that the chamber is in touch with the alloy. Apart from this, the melt goes through a valve where it faces extreme pressure. As a result, it goes into the close die. Generally, this process is ideal for alloys that feature a low point of melting.

Cold Chamber Method

In these units, the casting set is fixed outside the melt. For making components, this process fills the casting chamber with the alloy. Afterward, it is pressed into the molded wire in different channels. Generally, materials that feature a high melting point can use this process.

Long story short, this was an introduction to the die casting process. Hopefully, this article will help you get a basic understanding of this process. If you want to start a business in this field, we suggest that you consult an expert.
