METAL INJECTION MOULDING MIM

METAL INJECTION MOULDING MIM

METAL INJECTION MOULDING – MIM is very similar to the injection moulding of plastic parts. Metal powder and plastic pulp are baked into a “dough” that is injection moulded in the hot state. The part is then sintered to remove the plastic pulp and to give the metal its ultimate properties.

Extremely complicated shapes can be manufactured with high precision. The tool cost is slightly higher than for other types of casting, making MIM most suitable for large production runs. Since the degree of finishing is minimised to such an extent, the cost is much lower compared with the use of machining.

METAL INJECTION MOULDING – MIM

Metal injection moulding, MIM, is very similar to the injection moulding of plastic parts. Extremely complicated shapes can be manufactured with high precision.

SINTERING

A production technology in which a powder is compressed under high pressure in a closed tool to create the shape of the part.

PRECISION CASTING

By using what is known as the lost wax process, products can be cast with very high precision.

PRESSURE DIE CASTING

During pressure die casting molten metal is forced into a mould under pressure. A high degree of dimensional accuracy can be attained, which often results in less machining.

SAND CASTING

Sand casting is a cost-effective process for small and medium-sized production runs where the precision and surface requirements are not crucial factors.

MACHINING

Everything from simple to complicated machining. Cost-effective and where precision and demanding tolerance and surface requirements are specified.

FORGING AND HOT PRESSING

We often recommend forging or hot pressing when the requirements for strength are high. When the conditions are right, it is possible to save money by switching from machining to forging/hot pressing.

Assembly

Pre-assembled parts with integral components of varying kinds and materials. An all-in package at a fixed cost.
