Medical Metal Injection Molding

Metal injection molding mim meets the challenges of manufacturing complex medical device parts.

Medical metal injection molding. We have the knowledge and expertise to design engineer and produce medical devices that require thermoplastics liquid silicone or mim. Metal injection molding mim is a metalworking process in which finely powdered metal is mixed with binder material to create a feedstock that is then shaped and solidified using injection molding the molding process allows high volume complex parts to be shaped in a single step. Mim is the shorthand for metal injection molding it s a method of forming mixture of a metal powder and binder into a mold and then the mixture is granulated and then injection molding the desired shape of the initial parts and then through the high temperature sintering to get the expected metal parts with strength. Metal injection molding mim is a manufacturing solution that allows for production of intricate parts in medium to high volumes 10 000 to over 2 000 000 parts annually using fine 20 µm metal powders.

The metal injection molding mim process starts with the compounding or feedstock preparation process. Metal injection molding is used increasingly within the medical device industry to produce a variety of components. After molding the part undergoes conditioning operations to remove the binder debinding and densify the powders. Metal injection molding mim an advanced metal forming process that allows complex parts to be shaped in a single operation and in high volume a perfect solution for creating small complex metal components.

Mim process involves combining ultra fine metal powders and a polymer binder system to create a feedstock suitable for injection molding. Forum plastics is a global medical contract manufacturer serving oems and beyond for over 25 years with superior medical injection molding services. Adding plastic injection molding and metal injection molding mim to our list of capabilities demonstrates norwood medical s commitment to vertical integration. The iso 13485 2016 quality certifications investment in technology and the continuous commitment to exceed expectations make our experienced medical injection molding team an important partner in.

The metal powder to binder ratio is approximately 60 40 by volume. Net shaping mim technology has the distinctive ability to produce highly complex components with intricate surface details and custom textures. With mim you see a return on your investment with the value that is engineered into each and every component from design of your medical device all the way to your customer s doorstep. Fine metal powder less than 20µ particle size is blended with thermoplastic and wax binders in precise amounts.
