The key issue in the manufacturing of small precision metal
components is to guarantee the required performance at the
lowest possible cost. In most cases, where the components
have a simple shape and are made of traditional materials,
high-speed turning and milling can achieve the desired objective.
However, in the case of small geometrically complex components,
machining can be not only very expensive, but also extremely
difficult. When performance is not a limiting factor, Zn +
Al + Mg die-casting (or other low-cost alloys) can be an answer.
If, however, the component must have special mechanical and
chemical properties and production requirements are not very
large, precision casting can offer the best solution.
If production requirements are large and dimensional precision
must be especially accurate, only metal injection moulding
(MIM) can ensure satisfactory reliability at a competitive
MIM technology is more cost-effective than precision casting
for all the components that meet the following requirements:
- small size
- very complex geometry
- outstanding mechanical performance.
