Die Casting vs Foundry – What’s the Difference

Die Casting vs Foundry

If you’re in the market for metal parts, there are two processes you should be aware of—die casting and foundry. Though these two processes are often used interchangeably, they are actually quite different. In this blog post, we’ll break down the differences between die casting and foundries so that you can make an informed decision about which is best for your project.

Die Casting

Die casting is a metal-forming method in which molten metal is poured into a mould or die to form a desired shape. The process begins with melting the metal and then pouring it into a mould, where it cools and solidifies before being ejected from the mould. This process allows for precision parts to be produced quickly, making it ideal for high-volume production runs. Die castings also feature consistent surface finishes and dimensional accuracy that can’t be achieved with other processes.


A foundry is an industrial plant where metal objects are created by melting metals in furnaces and pouring them into moulds. The process begins with melting scrap metals in a furnace until they become liquid, at which point they are poured into sand moulds or plaster moulds that have been formed around a pattern (or “patterned”). Once cooled, the moulds are broken open to reveal the finished product. Foundries typically produce larger parts than those made through die casting due to their ability to pour thicker walls of metal. However, since each part needs its own custom mould, foundries are not as efficient or cost-effective as die casting when it comes to large production runs of identical parts.

Difference Between Die Casting and Foundry

  • Die casting is a process that uses moulds to create metal parts.
  • Foundry is a process that involves melting metal and pouring it into a mould.
  • Die casting is typically used for small, intricate parts.
  • Foundry is typically used for larger parts.
  • Die casting typically has a lower production cost than a foundry.
  • Die casting typically has a higher production rate than a foundry.


Die casting, and foundries offer two distinct methods of producing metal objects. Die casting is ideal for high-volume production runs due to its speed and accuracy, while foundries offer more flexibility when producing complex shapes or larger parts with thicker walls of metal. By understanding how these two processes work, you can make an informed decision about which one is right for your project’s needs!
