Innovation, quality, and strength, all in one cast.

Die casting uses a two-part, tool-steel cavity to create a negative shape of the required component. This “hole” is then filled with molten metal which is chilled back to solid before the cavity is opened and the cast metal part removed. Die casting is often used in the production of low-cost light metal components with high precision and strength. This article will define die casting, the types, materials, where it is used, and its benefits.

What Is Die casting?

Die casting is a manufacturing process in which molten metal is poured or forced into steel molds. The molds—also known as tools or dies—are created using steel and are specially designed for each project. This allows each component to be created with accuracy and repeatability. Aluminum, zinc, and magnesium are the most commonly used die casting alloys.

Die Casting Advantages

Die casting can have significant advantages over other manufacturing processes, which often lead to major cost savings, not only in the part price itself but also in the overall cost of production. When you cast a part, you can create complex net shapes, including external threads and complex internal features with minimal draft angles—minimizing secondary operations. You can also combine multiple parts into a single part, eliminating assembly operations and lowering labor costs, with the added benefits of simplified stock control and greater component consistency.

Other benefits include:

• Variable wall thicknesses
• Tighter tolerances
• Fewer steps from raw material to finished part
• Fast production cycle times
• Reduction in material scrap
• Long tool life, especially for zinc and magnesium

Die Casting Alloys

Zinc, aluminum, and magnesium are the three main die casting alloys. They are normally non-ferrous and their mechanical properties vary greatly to fit almost every type of application a manufacturer may need. Not only can die cast alloys withstand high operating temperatures, but they are also fully recyclable. Die cast alloys also have:
• Good corrosion resistance
• High strength and hardness
• High thermal conductivity
• High electrical conductivity
• Outstanding EMI/RFI shielding properties
• Good finishing characteristics
Separately, each die cast alloy offers a variety of benefits that the other may not offer. That is one of the great things about die casting, you do not have to be limited when it comes to choosing the right metal.

Die Cast Process

There isn’t one single process that can suit every project. Each project is different which is why Innovacasts offers multiple solutions for all die casting needs. This ensures the right process is always used for the right application. At Innovacasts, we offer three different types of die casting processes.

Hot-Chamber

Used for zinc, some magnesium alloys, and other low-melting, hot-chamber die casting is a great option for alloys that do not readily attack and erode metal pots, cylinders, and plungers.

Cold-Chamber

Better suited for metals with high melting points such as aluminum, during cold-chamber die casting, metal is liquefied and then ladled into a cold chamber where a hydraulically operated plunger pushes the metal into the die.

Injected Metal Assembly

Over the past 12 years, we have developed and refined our innovative; one-step manufacturing solution, Injected Metal Assembly. IMA outperforms most adhesives used for small component joining and assembly production and reduces manufacturing costs.

Experienced teams that work closely together deliver better products faster.

Every day we work collaboratively to find new opportunities and discover unique, high-value solutions for your product manufacturing.
