What Is a Foundry? Understanding Metal Casting in Adelaide and Australia

A foundry is a manufacturing facility where metal is melted and poured into moulds to produce solid objects. Although the process has ancient origins, foundries remain essential to modern manufacturing, particularly in industrial, mining, marine, agricultural, and infrastructure sectors.

In Adelaide and across Australia, foundries support industries that require durable, reliable components capable of operating in harsh environments. From replacement parts to custom-engineered components, foundries play a critical role in keeping equipment, assets, and infrastructure operational. Foundries also help bring to life artistic, hobbyist, restoration and commemorative projects involving metal.

What Does A Foundry Do?

Essentially, a foundry specialises in metal casting. This involves heating metal until it becomes molten then pouring it into a mold. The mold is the inverse of the desired shape and it can be simple or complex, depending on the item being made. The molten is allowed to cool and solidify in the mold. Once solidified, the casting is removed, finished, and inspected.

Casting is particularly valuable because it allows:

• complex shapes to be formed in a single process;

• strong, dense components to be produced; and

• custom or low-volume parts to be manufactured cost-effectively.

Foundries handle various metals, including iron, steel, aluminium, bronze, and brass. The choice of metal depends on the final product requirements such as strength, weight, corrosion resistance, and cost.

Types of Foundries

Foundries can be classified based on the casting process or the type of metal with which they work:

In terms of the metals used, foundries can be classified as:

• ferrous foundries, meaning they deal with metals containing iron; or

• non-ferrous foundries, working with metals that do not contain iron, such as bronze, copper, aluminium and other specialised alloys.

The main types of foundries based on casting processes are:

• sand foundries, which use sand molds as a cost-effective solution for creating various shapes.

• die casting foundries, which use metal molds for high-volume production.

• investment foundries, which use wax patterns coated with ceramic to create particularly detailed castings.

• permanent mold foundries, which use reusable metal molds, usually for medium-sized production runs.

  
  

Each type serves different industries and production needs.

Adelaide Brass Castings operates as a sand foundry using both ferrous and non-ferrous metals, supporting Australia with cast items designed for strength, corrosion resistance, and longevity.

From traditional brass to modern alloys

Historically, Adelaide Brass Castings produced items in brass. As the manufacturing scene and industry requirements changed over time, many applications moved away from brass toward other metals and alloys that offer improved performance, and we adapted our services accordingly.

Today, our foundry specialises in casting alternative ferrous and non-ferrous metals and alloys better suited to contemporary requirements.

Why foundries still matter locally

Despite global manufacturing options, local Adelaide foundries remain important. They provide faster turnaround times, direct technical collaboration, and an understanding of Australian operating conditions.

Foundries continue to be a cornerstone of South Australia’s manufacturing capability.
