Medical Plastics Injection Molding
FDA-registered medical plastics injection molding on an ISO 9001:2015 quality system.
Precision components built inside a documented quality system, not bolted on after the fact.
Why Medical Manufacturers Choose Crestwood
Injection molding is one of the most efficient, cost-effective ways to produce medical plastics and device components at the precision and quality medical applications demand. Our facility is ISO 9001:2015 certified and registered with the FDA as a medical device manufacturer, and our quality system covers incoming materials verification, in-process inspection, and finished-part validation.
That combination shows up in the parts we produce every day: engineering-grade resins molded to tolerances as tight as 2 microns, with full traceability from raw material to finished component.
Medical Plastics and Resins We Mold
Crestwood molds medical plastics in engineering-grade resins including ABS, acetal, acrylic, nylon and polycarbonate, along with low-tolerance and high-temperature resin options. The right resin depends on the component, how it will be used and the regulatory context it must meet, so we work through material selection with you project by project. See Plastic Resin Materials for the full range of resins we mold.
Our medical injection molding supports complex and multi-cavity tooling, shot sizes from 0.05 to 32 ounces, and production runs from 500 to 5 million parts. Sonic welding, milling, tapping, drilling, testing and assembly are available as secondary operations.
Secondary Operations Included
Sonic welding and precision assembly available in-house, so multi-component medical devices leave our facility ready for use, not just molded.
FDA-Registered Facility
Our facility is registered with the FDA, and every page of this site says exactly that, correctly.
Tolerances to 2 Microns
Automated, microprocessor-controlled presses hold the tight dimensional tolerances medical components require, run after run.
Precision Medical Components
Engineering-grade resins molded into the small, exacting parts medical devices depend on, with material traceability built in.
A Documented Quality System, Not an Afterthought
Medical device buyers know the difference between a supplier who claims quality and one who can document it. Every medical run at Crestwood is backed by incoming materials verification, in-process inspection, and finished-part validation, the same documented quality system that supports our ISO 9001:2015 certification.

What We Mold for the Medical Field
Frequently Asked Questions
Is Crestwood certified for medical device molding?
Yes. Crestwood Industries is an FDA-registered facility, certified to ISO 9001:2015, with a documented quality system built for medical device component manufacturing.
What is the difference between FDA-registered and FDA-approved?
FDA registration means the facility is on file with the FDA and subject to its regulations. The FDA does not approve manufacturers directly, it registers facilities and, separately, clears or approves specific devices. Crestwood is an FDA-registered facility.
What tolerances can Crestwood hold on medical components?
Our automated, microprocessor-controlled presses hold tolerances as tight as 2 microns, meeting the precision medical device components require.
