InjectAlloy®
Remington’s process for
metal injection molding (MIM), is a marriage of thermoplastic injection molding
and conventional powder metallurgy technologies.For small metal parts,
MIM offers the freedom to design complex shapes usually associated
with plastic injection molding or investment casting. As with any metalworking
technology, there are certain characteristics inherent to the process. This
design guide will provide the basic information necessary for designing metal
injection molded parts. For detailed recommendations, InjectAlloy® specialists
are available to assist in the design and fabrication of your parts.
The MIM process, using multicavity tooling, is well suited for the
production of geometrically complex parts in the mid- to high-volume range.
MIM can reduce cost when compared with smaller investment castings and
discrete machining, and to some extent, with conventional powder metallurgy
when significant secondary machining or assembly of the P/M part is required.
Metal injection molding typically will not compete directly with drop-off screw
machine components, stampings or die castings.However, assemblies made by combining
a number of small parts can often be molded as an integral piece by MIM. The process
is capable of forming complex configurations and has a degree of geometric freedom
equivalent to that of injection molded plastics or castings.
