What is Die Casting?

Since the 19th century, great progress has been made in the field of die-casting. In this article, we will discuss the basics of die casting and the different materials and processes. According to experts, if you want to create a process, this field is your most economical choice. With only one mold, you can produce thousands of castings. In addition, the quality of components will be the same and the cost will be very low. Let's learn more.

Definition

Basically, this automatic casting process involves pressing the liquid melt into the mold at very high pressure and speed. Pressure between 150 and 1200 bar, speed up to 540 km/h. Typically, this process uses alloys with very low melting points.

In most cases, this process is ideal for the mass production of various components. In addition, this process uses permanent molds.

Mould

As far as molds are concerned, they are made of high-quality steel. The two halves form a cavity to contain the liquid melt. The two parts are fixed on a machine plate. Apply high pressure to the mold.

In addition, the mold is cooled to make the melt have the desired shape. It takes a lot of money and time to produce moulds. But the good news is that once the mold is ready, you can make millions of castings.

Programs and Functions

In terms of die casting, components are manufactured using two different methods: cold chamber die casting and hot chamber die casting. No matter how the manufacturing process is, a special release agent will be prepared before the casting process. This is to ensure that there is no problem removing the casting.

However, they do not put the melt directly into the cavity. Instead, it is placed in the casting chamber and the alloy is pressed into the mold using a powerful piston.

Hot Chamber Method

One of the main features of this process is that the chamber is in contact with the alloy. In addition, the melt passes through a valve and is under great pressure. As a result, it goes into closed mode. Generally, this process is very suitable for alloys with low melting points.

Cold Chamber Method

In these devices, the casting is fixed outside the melt. In order to manufacture the components, this process fills the casting chamber with alloy. After that, it is pressed into the molded wire of different channels. Generally, materials with high melting points can use this process.

To make a long story short, this is an introduction to the die-casting process. I hope this article can help you have a basic understanding of this process. If you want to start a business in this field, we suggest you consult experts.
