Casting
Aluminium injection moulding
The aluminium injection moulding process involves the injection of liquid aluminium into a steel mould under high pressure. This process is fully automated and increases production speed significantly. Therefore it is suitable for high-volume production and complex shapes. Aluminium injection moulding provides clean and smooth surfaces which require very little post-treatment work.
Aluminium Coquille Casting
With the help of an aluminium coquille casting system, liquid aluminium is poured into a two-piece steel mould by means of a ladle. This process is suitable for smaller products and smaller volumes of production.
Lost wax method
The lost wax casting method involves the use of wax moulds to cast material and is suitable for complex shapes. Wax is sprayed into an aluminium or steel mould. The wax that comes out of the mould has the exact same shape as the actual end product. Here the entire wax product is coated with a ceramic layer. The whole product is then placed into a kiln, where the wax melts and flows out of the ceramic casing. The ceramic structure that remains is the actual mould that will be used to fill cast iron, bronze or aluminium. The lost wax method is known for its precision and is therefore very suitable for products which require a high dimensional accuracy and for large volumes of production.
Sand casting (cast iron)
In the sand-casting process, liquid steel is poured into a mould made of sand. Because the mould is made of sand, and is highly heat resistant, sand casting allows materials with high melting points to be cast. This technique is often used in the production of robust products, ranging from shipbuilding parts, mechanical engineering parts and offshore industry equipment.
