Since the 19th century, the field of die casting has come a long way. In this article, we are going to talk about the basics and the different materials and processes of die casting. According to experts, if you want to create processes, this field is your cheapest choice. With a single mold, you can produce thousands of castings. In addition, 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 molten liquid into a mold at extremely high pressure and speed. The pressure is between 150 and 1200 bar, and the speed reaches 540 km/h. Generally, this process uses alloys with a very low melting point.
In most cases, this process is an ideal option for mass production of a wide range of components. Also, this process makes use of permanent molds.
molds
As for the molds, they are made of high quality steel. The two halves create a cavity that contains the molten liquid. These two parts are fixed on a machine plate. High pressure is applied to the mold.
Apart from this, the die is cooled 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 melted part is removed without any problem.
However, they do not place the melt directly into the cavity. Instead, it is placed in the casting chamber and the alloy is then forced into the mold using a strong piston.
hot chamber method
One of the main features of this process is that the chamber is in contact with the alloy. Apart from this, the melt passes through a valve where it faces extreme pressure. As a result, it goes into the closed die. Generally, this process is ideal for alloys that have a low melting point.
Cold room method
In these units, the casting assembly is set outside of the melt. To make components, this process fills the casting chamber with the alloy. Then, it is pressed into the molded wire in different channels. In general, materials that have 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 gain a basic understanding of this process. If you want to start a business in this field, we suggest you consult an expert.
