Micro Material: The device is made from Ultem, an amorphous thermoplastic polyetherimide (PEI) resin.
Micro Features: The overmolded assembly design has a spring OD of 0.11″ (0.28mm). The Ultem wall thickness is 0.012″ (0.30mm).
Description: The assembly device and mating overmolded tube were components of an endoscopic suturing device used in a non-robotic, minimally invasive surgery. The laparoscopic procedure deployed a circular pattern of staples to create a closure.

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.
