What Knudsen Plast does
Knudsen Plast A/S is a Danish specialized contract manufacturer of injection moulded plastic components for the healthcare sector, founded in 1977 and headquartered in Frederiksværk, Denmark. The company operates two production sites: a Danish headquarters facility with 36 injection moulding machines and ISO Class 8 cleanroom capacity (described as one of the largest cleanrooms in Denmark), and a Slovak subsidiary in Vranov nad Topľou with 52 machines dedicated to high-volume production. Its technology stack includes closed loop injection moulding, 2K/3K multi-component moulding, clamp forces from 25T to 500T, vision control systems, ultrasonic and laser welding, tampon printing, automated assembly, and an in-house measurement laboratory equipped with GOM 3D scanning and Nikon iNexiv CNC measurement. The company is certified to ISO 13485:2016 (solely since June 2017) for design, mould development, injection moulding, assembly, and sterile packaging, and complies with FDA 21 CFR Part 820 Quality System Regulation.
Knudsen Plast serves medical device OEMs and healthcare companies seeking to outsource injection moulded component production. Its go-to-market is direct B2B sales targeting enterprise medical device customers, with engagement led by Managing Director Jens Kristian Pedersen and Business Development Director Lars Bo Poulsen. The business model is professional services-style contract manufacturing: customers either outsource new production or transfer existing tooled production to Knudsen Plast, with a documented '15% cost savings' value proposition for volume manufacturing in Slovakia versus Denmark. Revenue streams include core injection moulding, full outsourcing packages (tool transfer, validation, ramp-up, volume production), validation services (IQ/OQ/PQ, PPAP), test center services, assembly and finishing, and managed supply chain services including Vendor Managed Inventory that replenishes millions of products weekly and delivers sterile medical equipment to hospitals.
In February 2026, Knudsen Plast was acquired by MGS (Manufacturing Services International), a global healthcare Contract Development and Manufacturing Organisation headquartered in Germantown, Wisconsin. The acquisition makes Knudsen Plast part of MGS's combined 1,600-person, 13-facility European operations and is MGS's third Danish deal within 16 months. The company was previously recognized with the Børsen Gazelle 2024 growth award and an EcoVadis Bronze Medal for ESG performance, and has received multiple EU Regional Development Fund grants to upgrade its Slovak facility's technology and innovation capacity.
