Thin Wall Micro Molding Ejector Ring Device

« »

Micro Material: This device is molded from Ultem, an amorphous thermoplastic polyetherimide (PEI) resin.

Micro Features: This ejector ring features thin wall micro molding, measuring .009″ (.23mm) wall thickness restricted in four locations to .0035″ (.09mm).

Description: This ring design features multiple three-plate gates into a .009″ (.23mm) wall, leaving little room for error. Our expertise and experience with thin wall micro molding to tight tolerances allowed us to succeed where others could not.

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.
