What Are The Advantages and Disadvantages of Die Casting and Injection Molding?

When you need to make a part, you will consider whether you want to make it by die casting or by injection molding. To help you choose which method, the following describes the advantages and disadvantages of die casting and injection molding.

What Is Die Casting and Injection Molding?

Although die casting and injection molding are two different processes, their principles are basically the same. First, you need to prepare a model that matches the shape of your part, liquefy the material, and then inject the liquefied material into the model. The mold is then cooled with a cooling device. In general, die casting and injection molding need to be completed by machine. Die casting needs to be done by metal die casting machine, while injection molding needs to be done by plastic injection molding machine. 

Although the principles of die casting and injection molding are basically the same, there is a major difference between them. Die casting is suitable for making metal parts, while injection molding is suitable for making plastic parts. So if you want to make plastic parts, you need to use an injection molding machine, and if you want to make metal parts, you need to use a hot chamber die casting machine.

Benefits of Injection Molding

Because the pneumatic injection molding machine is easy to use and the molding process is flexible, the production speed of the injection molding process is fast. At the same time, the injection mold can accommodate different kinds of plastic or polymer materials. In the production process, the vertical injection molding machine can inject fillers into the mold to increase the strength of the product.

Benefits of Die Casting

Die casting machine has high production efficiency and high precision. In the production process, the operator does not need to carry out the second operation. Die casting process can be used to manufacture various parts with complex structure. Energy-efficient die casting machine can produce high quality products, thus prolonging the service life of parts. 

Difference between Injection Molding and Die Casting

If you want to produce a large number of parts at a very low cost, you can choose injection molding rather than die casting, because the labor and material costs of injection molding are relatively low. But it should be noted that the cost of multifunctional injection molding machines and other auxiliary equipment can be very high. 

If you want to make many complex and precise parts in a short time, then die casting is your first choice. Metal parts produced by low consumption die casting machine have better durability and texture than plastic parts produced by horizontal injection molding machine. 

As two common processing technologies, die casting and injection molding are widely used in various fields. These two methods have their own advantages and disadvantages, so consumers should choose the most appropriate process according to their own needs. But both processes need to be done by machines. Therefore, for enterprises, they can complete processing by purchasing processing machinery, while for individuals, they can contact some processing plants to complete processing.
