Die Casting or injection molding is the manufacturing process in which molten metal is poured or pressed into steel molds. These moulds, which can also be called tools or dies, are specially designed for each project.
Nowadays, it is very difficult to imagine modern life without this manufacturing method. It is one of the most efficient ways to produce high quality parts in an economical way. Furthermore, this technique has an almost limitless number of uses for castings. From the body of your phone to parts of your car, lampposts, pipes…etc. Therefore, in this article we will explain what die casting consists of and how it works.
How does this Die Casting process work?
In the high-pressure casting process, molten metal or metal alloy is injected into the mold at high speed and pressure.
Although the idea of injecting molten metal into a mold is easy to understand, in real life die casting is a very complex process, and there are many variables that affect the result. It certainly requires specialized equipment and deep experience from the foundry team.
In the first place, to carry out this process, machines are needed, which, depending on the material used, the injection unit that fills the mold can be a cold chamber or a hot chamber.
For one, in hot chamber die casting, the metal is held within the die casting machine itself. It is then extracted into the chamber and introduced into the mold by the action of the injection piston. These parts of the machine are always in contact with the molten metal.
On the other hand, in the cold room process, the metal is first melted in a separate furnace and transferred to a holding furnace. Subsequently, it is poured into a filling chamber and injected into the mold.
Today, die casting machines can be fully automated and carry out all process steps without human intervention.
What metals can be used?
Zinc, aluminum, magnesium, lead and tin are the main die-cast alloys. They are all non-ferrous metals and their mechanical properties vary to suit any type of application. These alloys withstand high operating temperatures, and are fully recyclable. They also have other features, such as:
* Good corrosion resistance
* High strength and toughness
* Thermal conductivity
* High electrical conductivity
* Exceptional EMI or RFI shielding properties
* Good finishing characteristics
Separately, each alloy offers a variety of benefits that the other may not. That is one of the biggest advantages of die casting. There are no limits when it comes to choosing the right metal.
In which sectors can this technique be used?
Today, the industry that uses this technique the most in its production process is the automotive industry. However, there are thousands of applications for castings in other industries.
1. Automotive industry
2. Aerospace
3. Accessories
4. Furniture
5. Power tools
6. Electronics
7. Machinery
8. Lighting
What benefits does Die Casting bring?
This technique has many advantages over other manufacturing processes that lead to significant cost savings, not only in terms of the price itself, but also in the total cost of production.
In addition, the die-cast parts are 100% recyclable.
