Foundry Casting of molten metal into a usable product is a process with roots going back thousands of years. They hold the ability to form a wide range of complex parts in a variety of metals for various industries.
The process has evolved to produce bigger castings and larger quantities, but the fundamentals are still the same. A pattern of the required product is created and used as the mould. Molten metal is poured into the mould and allowed to cool. The casting is then removed from the mould, fettled to remove excess material and then finished as specified.
All metals offer different properties. Each set of properties lends itself for a particular group of products. Aluminium, with it’s lighter weight and versatility, is used in components for car manufacturing, pumps and gearboxes through to architectural finger signs.
Brass and bronzes offer high strength, corrosion resistance, low friction, antibacterial properties and a golden colour and as such, its uses range widely, from plaques to decorative castings e.g. door handles and even street furniture.
White Metals, with it’s low melting point and it’s anti friction properties is commonly used in bearings to prevent wear.
Some features cannot be introduced into the product during the casting process, possibly due to the small tolerances of the design dimensions. In such circumstances, a “Machining Allowance” is introduced at the design stage in order for the casting to be machined back to the exact size.
