Metal parts compose every existing machine and equipment. It is important for companies to invest in parts that are cost-effective, durable and easy to reproduce, among other advantages. Die casting is a manufacturing process that guarantees ideal metal parts for numerous industry fields. Factory owners and operators can benefit from learning more about die casting, including the different alloys used, the process and several benefits.

The Alloys

Magnesium, zinc and aluminum are the most common alloys in die casting. These alloys have numerous qualities that make them perfect for the process.

  • Flexible in operation and mold
  • Recyclable
  • Resistant to high temperatures
  • Heat and electricity conductible

These alloys also have individual properties in addition to the more common ones. These features can be especially beneficial to certain industries and functions.

The Processes

Die casting takes place when molten metals are shaped by steel molds using high-pressure. These molds change depending on the parts requested by the client. There are different types of processes depending on the alloys used. Hot chamber pressing is common on alloys with low melting points such as zinc and most magnesium combinations. Meanwhile, the cold chamber approach is used with aluminum die castings, which have a high melting point. The molten metal is placed in a cold chamber before molding.

The Advantages

The die-cast process is preferred within the industry due to its numerous advantages. Clients can request different mold types and alloys, allowing for flexibility during decision making. The process also offers a faster production cycle and reduces the amount of leftover material, resulting in overall lower costs for the customer. Finally, the materials used in die casting tend to have longer tool lives, specifically magnesium and zinc.

Die casting is a common procedure in component production. However, it is also a dependable and long-lasting procedure that results in lower costs, greater efficiency and other incentives for company leaders.
