Micro Material: The clip is made of Ultem 1010 thermoplastic resin.
Micro Features: The clip component measures 0.009″ (0.23 mm) in wall thickness.
Description: The clip device is made of a high-strength polymer that flows better than PEEK, but not as good as Polycarbonate. In this application the S-shaped geometry was used as a molded spring to create friction in a infusion pump. One challenge was selecting a gate location that developed a knit line without compromising the integrity of the spring. MicroFlow analysis was used to optimize the runner and gate geometry. This complex tooling solution required a double side action, contoured parting line with a jumped parting line feature.

Medical micro 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.
