Process | Powder injection moulding |
---|---|
![]() |
Mainly for small parts which require accurate and complex geometry. Ceramic or metal powders mixed with a plastic substance are heated, and then injected into the mould.
For ceramic powders, water (traditional ceramics) or organic materials such as plasticizers (technical ceramics) are added to provide adequate plasticity for forming. The major difficulty is removing the organic material prior to firing, without causing cracks or distortions. Production volumes are medium to large. |
