Metal injection moulding (MIM) has over the past decade established itself as a competitive manufacturing process for small precision components which would be costly to produce by alternative methods. It is capable of producing in both large and small volumes, complex shapes and from almost all types of materials including metals, ceramics, intermetallic compounds, and composites.
Metal injection moulding (MIM) is a development of the traditional powder metallurgy (PM) process and is rightly regarded as a branch of that technology. When using traditional processing powder is compacted in a mould which then has to be ejected which means parts with undercuts or projections at right angles to the pressing direction cannot be made directly. That limitation is substantially removed by the metal injection moulding process developed during the last decade and now expanding rapidly.
