STEP #02Choice of material
The choice of material for the mould is to be made according to the desired material properties. For example, a mould for plastic injection moulding must be able to withstand high pressure and not distort. In addition, you must be able to remove the mould without the product emerging damaged from the mould. Some moulds are used once for a unique product – also known as the ‘lost mould’ method. For large production runs we use other more durable moulds. An injection mould is often made of tool steel, but it can also be made of aluminium or another metal.
