5 Benefits of Die Casting for Manufacturing Processes

Die casting refers to the metal manufacturing process where molten metal is forced to form into tooling cavities under high pressure. The raw metal is heated and then forced into a mould cavity. After the molten metal has solidified or cooled, the new casting is ejected. It makes it easy to obtain differently shaped metals nowadays.

From engine blocks to cylinder heads, die casting creates a wide variety of products. The die casting process is quite versatile. Here are 5 more benefits for manufacturing companies. 

1. Supports Different Metals and Alloys

Die casting supports a wide variety of alloys and metals. Zinc is one of its most popular choices for the casting process, due to its high strength and ductility. It is relatively cheap, which makes it an ideal choice for large scale manufacturing applications. Other alloys and metals supported by die casting include magnesium, copper, aluminium, lead and tin. 

2. Creates Super Smooth Castings

With die casting, manufacturers don't need to worry about creating rigid casting surfaces. Because it involves the use of pressurized molten metal, it creates smooth surfaces on casting. The process involves forcing the molten metal into the mould cavity. This causes it to fill the otherwise void space, ensuring a smooth surface. 

3. Minimized Finishing Operations

Another benefit of die casting is the ability to minimize finishing operations. With other casting processes, the castings are finished with the use of a machine, these secondary operations can be cumbersome and time-consuming. With die casting, most castings are ready to be shipped right after the casting process. 

4. High Precision Casting

Die casting produces high-precision products. It provides parts which are dimensionally stable, durable and have the feeling and appearance of quality products. It also provides complex shapes with closer tolerances compared to other processes of mass production.

Die castings materials can be produced with thinner walls compared to those obtained from other casting methods. They are also much strong than plastic injection mouldings with similar dimensions. 

5. High Production Rates

With very little machining required, die casting can have a high production rate. It can also produce thousands of virtually identical castings with specific tolerances before the need for additional tooling arises. While one of its benefits is that it produces super smooth castings, die casting can also produce casings which simulate a wide variety of textures.

Die casting is an economical and efficient alternative to other processes. When used to its maximum potential, it can replace the assemblies of a wide variety of parts produced by various processes while creating significant savings in labour and cost. Contact die casting companies to learn more.
