Do you need to produce a large number of metal components? While this can often be a costly and lengthy process, techniques like die casting, can provide a more economical and swift solution, making it a suitable option. Pressure die casting precisely forms parts using metals such as magnesium, aluminum, or zinc.

Additionally, if you collaborate with a skilled manufacturer, you have the opportunity to apply various finishes to your components. This versatility—along with its capacity to create precise, sturdy, and high-quality components—underscores the advantages of die casting, particularly for large-scale production.

How does die-casting work?

Die casting’s capabilities lie in how it works. It’s like injection molding, except this time, it is exclusively for metals. As such, it requires a custom mold, which professional engineers and toolmakers will make based on your design. When it’s ready, it will be installed on the die-casting press. Then, the process begins by injecting molten metal under pressure inside the tool cavity. Once the part is ready, it can be finished in different ways, such as anodizing or powder-coating.

Different ways to make your parts

Did you know die-casting can be done in two ways? Here’s how:

• Gooseneck or hot chamber die casting

  This is the widely used method for die-casting parts, and it involves immersing the injection mechanism’s chamber into molten metal. Then, a metal feed system resembling a gooseneck introduces the metal into a die cavity.

• Cold chamber die casting.

  If machine corrosion is a concern, die casting in a cold chamber is a better choice. This time, the molten metal will be transferred directly into the injection system. As such, there is no need to immerse the injection mechanism into motel metal.

Is die-casting right for you?

Die casting may benefit your project if you need to produce identical metal parts for low to mid-volume production. It’s a repeatable process that will provide accurate parts with good surface finishing. Plus, it’s possible to make complex components.
