Advantages of
P/M
 |
Ability to produce high precision
components in volume. |
|
Only the exact amount of material is used. |
|
Net shape production, eliminates or minimizes
machining. |
|
Density, or conversely porosity, can be
accurately controlled MIM Parts to suit particular
requirements. |
|
Allows combination of materials which
cannot be produced in any other way, including dissimilar
metals, non-metallic and materials with widely differing
characteristics. |
|
Allows design in of self-lubricating properties. |
P/M offers designers and users a versatile and efficient
method Parts of producing parts and components. The process
is versatile because it is applicable for simple as well
as complex shapes, and a full range of chemical, physical
and mechanical properties are achievable. The process
is efficient because it produces moderate to high volume
net or near-net shapes, with almost no raw material loss,
economically.
Advantages
of MIM
|
MIM Parts produced with feedstock
can reach density levels up to 99.5% which exceeding
traditional press and other sintering techniques. |
|
MIM process can produce more complex parts
than other traditional stamping or sintering techniques. |
|
The tensile strengths, elongations and
hardness are superior to other traditional techniques
or machining method. |
|
The dimensions of MIM parts can be held
at tight tolerances. |
|
The cost and time saving can be realized
by eliminating secondary operations and machining
steps. |
Metal
Injection Molding (MIM) process is an advanced metallurgical
technology that integrates the shape-making capability
of plastic injection molding with the material flexibility
of powder metallurgy. The uniqueness of MIM has enhanced
the ability to manufacture high integrity metal parts
in complex shapes of precise dimensions. Almost any high
melting point ferrous metal that can be produces in suitable
powder form can be processed by MIM.
