Shell Casting
Shell Castings utilise a thin-walled sand-based mould into which the molten metal is poured. This mould is created using a metal piece shaped as the required component to form the pattern, and is reused to form multiple shell moulds. This reusable pattern allows for higher production rates, better dimensional accuracy and is used for small to medium components.
Gravity Die Casting
Used to manufacture casting parts from non-ferrous materials such as aluminium or low temperature alloys. This technique is used to create intricately shaped components. It involves pouring molten metal, under the force of gravity, into a preformed precision machined block, also known as the die.
Airset Sand Casting
Airset Sand Casting involves placing a mould pattern of the casting into the sand. A gating system is then setup which involves adding a pouring cup and tunnels (or gates) to the mould which will be used to feed the molten metal into the cavity.
The sand will take up the form of the mould which can then be removed, leaving a void for the metal to fill. The mould is then filled with the molten metal, resulting in the component being cast. Once cooled, the mould is broken open to reveal the required casting.
Green Sand Casting
Green Sand Casting is the process of mixing sand, clay and water as the binding agent which is rammed around a pattern to form a mould. This is the most common casting process.
