What Polymer Conversions does

Polymer Conversions, Inc. is a Western New York-based medical contract manufacturer founded in 1979 (incorporated December 1978) by Jack and Joan Bertsch, specializing in clean room thermoplastic injection molding for medical device, life science, pharmaceutical, biomedical, dental, and veterinary OEMs. The company operates from a headquarters facility at 5732 Big Tree Road in Orchard Park, NY, on a 15-acre site with 22,000+ square feet of Class 7 (10,000) and Class 8 (100,000) clean room capacity and a fleet of 25-26 injection molding presses ranging from 28 to 390 tons equipped with 3-axis servo robotics. Core technical capabilities include a proprietary real-time, fully validated product and process monitoring system networked to every press with cloud-based secure backup, scientific molding techniques led by RJG-certified Master Molders, a full in-house tool room, Frigel Microgel closed-loop cooling, and Fanuc 6-axis robotic assembly cells with inline vision systems for 100% quality inspection. The company's QMS is registered to ISO 13485:2016 and ISO 9001:2015 (audited by NSF International), with FDA registration and compliance with FDA 21 CFR Part 820 and cGMP standards. Revenue is generated through quote-based per-part pricing, tooling fees, and value-added secondary services including pad printing, ultrasonic welding, heat staking, two-shot molding, robotic assembly, and packaging, with a documented tool transfer program supporting customer onboarding.

The firm pursues a direct enterprise sales model targeting medical device OEMs through dedicated project engineers, trade show presence, and inbound digital channels (LinkedIn, website, quarterly newsletter, YouTube), without any reseller or distributor network. Named enterprise customers include Abbott Point of Care (i-STAT cartridge components held to ±0.001" tolerances), SensGard, Medi-Pals, Sherwood Harsco, and historically GE, Fisher-Price, and NCR. In 2014 the Bertsch family created SILIKON Technologies LLC as a sister company to extend into precision silicone injection molding for healthcare, aerospace, and electronics. On August 31, 2020, Polymer Conversions was acquired by Medbio, LLC, a portfolio company of Graham Partners, combining two complementary medical device contract manufacturers into a single PE-backed platform; the Polymer Conversions website now redirects to Medbio.
