A Southern California based Outsourcing Specialist with more than 25 years of experience in the field of Plastics, Metals and Chemicals.
Metal Injection Molding is an industrially beneficial technology which allows engineers to create complex-shaped, often extremely small metal parts, which are complicated to manufactures with conventional lathe, CNC, EDM, and spark-machining methods regardless of ferrous metal alloys.
MIM can produce complex parts quickly, and at a lower cost than conventional techniques, such as machining or investment casting. MIM technology allows device engineers a previously unobtainable level of freedom in the design process, and the ability to produce high-density components.
Since the parts are made of metal or alloy material, purity and corrosion resistance are significantly better than with cast. Producing close to net-shape parts slashes costs when compared to machining, and Metal Injection technology often allows for the replacement of an assembly of parts with one discreet component.
MIM parts can serve as replacements of key high-tolerance plastic molded parts where strength and long-term dimensional stability is required.
