MIM / CIM / PIM
Combining Metal Injection Molding (MIM) technique, Ceramic Injection
Molding (CIM) technique and Plastic Injection Molding (PIM), MEM can
manufacture any complicated geometry.
The MIM is a metalworking process where finely-powdered metal (<20 μm)
is mixed with a calculated amount of binder material to comprise a
feedstock capable of being handled by injection processing equipment
through a process known as injection mold forming. The MIM process is
typically explained as four steps (Compounding, Molding, Debinding and
Sintering) to produce a final part or device that may or may not need final
finishing operations. MIM process is most applicable to materials that are
difficult to machine, materials with multi-phase microstructures, or high
work hardening materials.
Using MIM technique is possible transforming complex concepts and
designs into high precision, superior final properties and net-shaped
products and is commonly used to manufacture parts and devices
weighing from 0.1gm to 250 gm. Cross sections are typically less than
6.35 mm. but, parts are not limited to this combination of mass and
cross section. Tolerances are on the order of ± 0.3 to 0.5%, although
specific dimensions can be held as close as ± 0.1%. An assorted variety
of metals are capable of implementation within MIM; these contain the
same alloying constituents found in industry standards for common and
non-conventional metal applications. MEM is capable to manufacture
parts and devices for different industries working with carbon steels, low
alloy steels, stainless steels, low expansion alloys (kovar & invar),
tool steels, soft magnetic alloys, super alloys, to conductive materials (copper),
bi-materials, non-ferrous metals, as well as innovative materials.
CIM Ceramic injection molding (CIM) has been practiced for more than
30 years, however, it has been delimited to specific applications with artless
geometries such as the ceramic cores for investment casting. MEM expertise
on Ceramic Injection Molding (CIM) has mastered in applications for several
industries through the intelligent feedstock formulations searching for material
properties requirement such as chemical inertness, high temperature stability,
wear resistance and electrical insulation offering to our customers a cost-effective
production of parts and devices with a range of geometric complexities.
MEM manufactures ceramic components with wall thickness of 1 mm and
employs a color technology that can dye ceramics in various particular colors.
The type of ceramic materials used is not restricted to alumina and zirconia.
