Ultem Fixation Screw

Micro Material: The screw is made of Ultem, an amorphous thermoplastic polyetherimide (PEI) resin.

Micro Features: The device features an end of flow, which is a feather-edge condition.

Description: This design from our customer called for pushing a difficult flowing material to a feather-edge while maintaining exacting tolerances. The specifications for the screw required a very exact micro tooling design in a highly capable molding system.

Medical micro injection molding is what we do. And all we do.

We’ve made millions of micromolded medical parts. We know how to produce the high quality our customers demand for applications all around the body.

We have years of expertise in problem-solving the most challenging micro part designs, including ones that feature ultra-thin wall stocks, high aspect ratios, and extremely tight tolerances.

Thermoplastics are a great micromolding material to work with as they become pliable above a specific temperature, but return to their rigid state upon cooling. The challenge with thermoplastics is knowing when a seemingly minor change in the design or an alternative thermoplastic material choice can significantly impact the quality and cost-effectiveness of the part.

MTD’s advanced technologies and flawless tooling execution helps customers achieve the highest results possible.
