Process Comparison

Eliminating multiple processes to achieve a desired geometry means eliminating additional cost and waste to make the smallest, most complex parts at high volumes with faster lead times.

Titanium Injection Molding is capable of creating complex components through a seamless process. Small, complex geometries that require a large volume of material to be removed via multi-axis CNC machining are ideal candidates for Titanium Injection Molding. Other manufacturing processes such as machining, investment casting and conventional PM are unable to produce thinner wall sections, holes and threads without multiple steps.

Wall thickness larger than 0.020” and smaller than 0.5”
Minimum draft 0.5°
Cored out features to reduce part weight
Flat surfaces


Asymmetry Ribs and bosses
Grooves and threads
Decorative features (i.e. texture, logo, lettering)


Small diameter holes <0.050”
Sharp corners or points
Wall thickness <0.020”
No draft
