Metal injection moulding (MIM) is a hybrid technology whereby it integrates the shaping capabilities of plastic injection moulding and materials flexibility of conventional powder metallurgy.

MIM is preferred for mass manufacturing of small, intricate-geometry components of a variety of materials as it can achieve 95% to 98% of its wrought materials properties at a much reduced cost.

The Technology

The initial step to MIM is material selection and preparation. Once the appropriate combinations of metal powder and plastic binders are blended and compounded, an injection mouldable feedstock is produced. Using an injection-moulding machine, the parts produced are then subjected to a binder removal process. Depending upon the type of binder used, different methods of debinding are applied. The parts, after debinding, will then go through a sintering process to ensure the parts are of the right material composition, physical properties and correct geometry.

The Advantages

• Greater design freedom With MIM, parts can be designed and manufactured without any design restrictions. In addition, almost all design changes are possible within the shortest development cycle and turnaround time.

• Miniturisation MIM technology is the best viable process for producing miniature parts economically.

The Applications

MIM technology has found increasing applications in the commercial world, from home applications to watches, automobiles to aerospace, medical to weaponry.
