MIM (Metal Injection Molding)

MIM & The REM® Process

Metal Injection Molding (MIM) is an effective way to manufacture complex and precision-shaped parts from a variety of materials. The MIM process can produce complex shapes with excellent strength for up Metal Injection Moldingto 50% less than the cost of CNC machining or casting for high volume manufacturing.  The ability to impart a superior surface finish upon these complicated shapes is a challenge which REM’s isotropic superfinishing technology (the REM® Process) can address for cost-conscious high volume manufacturing.

Industries such as automotive, electronics, medical, orthodontics, industrial, firearms and defense utilize MIM to meet product functionality and specification.  The REM Process allows the end-user to achieve an unmatched final surface quality removing parting lines, injection points and improving the overall surface finish while maintaining part geometry.  Traditional, abrasive mass finishing processes are time-consuming, generate copious amounts of sludge, and are a bottleneck for production throughput.  Metal parts with complex geometries are difficult to hand polish.  Both of these techniques can result in high overhead costs and quality challenges leading to lower than desired first pass yield.  Via the use of chemically accelerated finishing technology, the REM Process solves these problems by reducing labor, cycle times, and maintenance costs while increasing first-pass yield and producing a smooth defect-free surface, perfect for end-use or painting, coating, and the like.

Let REM’s team of surface engineering specialists help develop and deliver a REM Process for your applications.  Contact us today to discuss how REM can solve your MIM production challenges.
