Titanium metal injection molding (TiMIM) is a viable and competitive manufacturing method for small, complex titanium components. Once regarded as unfeasible or prohibitively expensive, TiMIM is rapidly being adopted as a go-to forming method for mid to high volume titanium implants.
The titanium metal injection molding (TiMIM) process is a method of manufacturing near-net shape components at production volumes from titanium alloys. Unlike investment casting and additive manufacturing techniques, TiMIM has high density and low contamination potential, making it a preferred method for manufacturing medical implants, high-strength mechanical components, and other demanding applications.
Titanium metal injection molding (TiMIM) is a method for high volume, precision manufacturing of small parts. TiMIM is performed by mixing titanium powder with a binding agent to form a thermoplastic compound. The compound is injected into a mold using an automated injection molding machine. The part is then removed from the mold and heated to remove the binder and densify the part, leaving behind a pore-free, dense part made to very tight tolerances and delivering excellent mechanical properties.
While metal injection molding (MIM) techniques are widely used in the medical device industry, there are distinct advantages when using medical-grade titanium alloys. The titanium metal injection molding (TiMIM) process produces pore-free parts that provide better corrosion resistance and biocompatibility than stainless steel alloys. Titanium is also significantly more efficient when used in ultrasonic applications.
