What Plas-Tech Engineering does

Plas-Tech Engineering, LLC is a medical device contract manufacturer headquartered in Lake Geneva, Wisconsin, specializing in precision plastic injection molding for the medical device, pharmaceutical, and biotechnology industries. Founded in 1991, the company provides end-to-end contract manufacturing services from concept through commercialization, including pre-sales consultation, engineering, prototyping, tooling, molding, assembly, packaging, quality/regulatory compliance, and sterilization. The company operates FDA-registered, ISO 13485-certified facilities with ISO Class 6, 7, and 8 cleanrooms, and employs Scientific Injection Molding (SIM) with Kistler transducers for process control. Its branded product portfolio includes the Equinox® line of pre-fillable syringes (silicone-free and glass-replacement solutions using COC, COP, polycarbonate, and polypropylene materials), SmarTUB® nested syringes for automated filling lines, a novel glass-replacement PFS syringe line for light-sensitive drugs, and a patent-pending tamper-evident syringe case.

The company makes money through two primary revenue streams: custom contract manufacturing services for enterprise medical device and pharmaceutical customers (priced via project-based quotations with multi-year contracts), and direct hardware sales of branded pre-fillable syringes and specialty syringe products. Sales are conducted through a consultative enterprise field sales model with dedicated project managers overseeing engagements from initial design review through production. In November 2025, H&T Presspart (a division of Germany's Heitkamp & Thumann Group) acquired a majority stake, positioning Plas-Tech as a U.S. manufacturing hub within a larger pharmaceutical component group while it continues to operate under its own brand.

The company differentiates through 30+ years of medical device manufacturing expertise, vertically integrated in-house tooling with 24-hour lights-out machining, robotic cleanroom automation enabling 24/7 production, and proprietary SIM technology. It serves customers across medical device manufacturing, pharmaceutical packaging, ophthalmology, and other regulated precision applications, with a recent 25,000 sq. ft. facility expansion underway to scale capacity.
