Metal Injection Molding (MIM) is a metalworking process which allows shaping and manufacturing , geometrically complex parts in single operation and in high volume. The economic advantage in metal injection molded parts lies in complexity and volume for small-size parts.
ETP has in-house ability to design and manufacture tooling that can hold both the requirements of the finished part and the potential complications of the subsequent manufacturing process, which is the most important element in the success of the process .
The fine metal powder is mixed with binder s and additives (various thermoplastics, waxes, and other materials), resulting in a 'feedstock' capable of being granulated and then injection molded into single / multiple cavities forming a green component . The green components then pass through various processes like, debinding, sintering, and other secondary operations, resulting in a final desired shape.
Dimensional tolerances of +/-.003" per linear inch can be commonly attained, so as, far more closer restrictions on tolerance possibly can be attained with expert technical knowledge and experience in molding and sintering. MIM can produce parts where it is difficult, or even impossible, to efficiently manufacture an item through other means of fabrication.
