Since the 19th century, the field of die casting has achieved a lot of progress. In this post, we are going to discuss about the basics and different materials and procedures of die casting. According to experts, if you want to establish procedures, this field is your most cheap alternative. With just one mould, you can manufacture thousands of castings. Moreover, the quality of the components will be the same and the cost would be quite low. Let’s find out more.
Definition
Basically, this automated casting method includes forcing the liquid melt into a mould at incredibly high pressure and speed. 540 km/h is the top speed and a pressure range of 150 to 1200 bar. The alloys typically used in this method have a relatively low melting point.
In most circumstances, this technique is a good solution for the mass manufacture of a wide range of components. Moreover, this procedure makes use of permanent moulds.
Molds
As for as moulds are concerned, they are manufactured of high-quality steel. The liquid melt is contained within a cavity created by the two halves. A machine plate holds these two pieces in place. High pressure is applied to the mould.
Apart from this, the die is cooled down in order to give the desired form to the melt. Making a mould is an expensive and time-consuming process. But there’s good news: once the mould is ready, you can manufacture millions of castings.
Procedures and functionality
Components for die casting are made by two different processes: cold chamber and hot chamber die casting. both are used. Regardless of the production procedure, a unique releasing agent is developed before the casting process. This is to make sure that the cast section gets removed without any issue.
They don’t, however, push the melt into the cavity immediately. Instead, it is poured into the casting chamber and then the alloy is pressed into the mould using a forceful piston.
Hot Chamber Method
The chamber is in direct contact with the alloy, which is a key component of this method. Apart from this, the melt goes via a valve where it experiences severe pressure. The consequence is that it is placed in the close die. Alloys with a low melting point are good candidates for this method.
Cold Chamber Method
As the name implies, the casting set is permanently installed outside of the melt in these machines. For producing components, this procedure fills the casting chamber with the alloy. Afterward, it is forced into the moulded wire in separate channels. Generally, materials that exhibit a high melting point can use this technique.
Long storey short, this was an introduction to the die casting process. This post should have provided you with a basic grasp of how this procedure works. I hope it did. We recommend consulting with an expert if you’re thinking about starting a business in this area.
