metallurgy PM & metal injection molding MIM processing
.
Powder
metallurgy (PM) is a term covering
a wide range of ways in which materials or components are made
from metal powders. PM processes can avoid, or greatly reduce,
the need to use metal removal processes, thereby drastically
reducing yield losses in manufacture and often resulting in
lower costs.
Mixing of
powders
This can often involve the introduction of
alloying additions in elemental powder form or the
incorporation of a pressing
lubricant.
Forming of the mixed
powder into a
compact
The dominant consolidation process involves
pressing in a rigid toolset, comprising a die, punches and,
possibly, mandrels or core rods. However, there are several
other consolidation processes that are used in niche
applications.
Sintering of the compact
to enhance integrity and
strength
This process step involves heating of the
material, usually in a protective atmosphere, to a temperature
that is below the melting point of the major constituent. In
some cases, a minor constituent can form a liquid phase at
sintering temperature; such cases are described as liquid phase
sintering. The mechanisms involved in solid phase and liquid
phase sintering are discussed briefly in a later
section.
Secondary
operations
The application of finishing processes to the
sintered part. In the Powder Metallurgy industry, such
processes are often referred to as secondary
operations.
Metal injection molding (MIM) is
a metalworking process in which finely-powdered metal
is mixed with binder material to create a"feedstock" that is
then shaped and solidified using injection
molding.The ability to
combine several operations into one process ensures MIM is
successful in saving lead times as well as costs, providing
significant benefits to manufacturers. The metal injection
molding process might be a green technology due to the
significant reduction in wastage compared to "traditional"
manufacturing methods.
