About Gsell
Gsell Medical Plastics AG, headquartered in Muri (AG), Switzerland, is a family-owned company founded in 1984 specializing in custom solutions made from high-performance plastics and hybrid material composites. The manufacturing portfolio covers CNC machining (turning and milling), high-temperature injection molding including overmolding of insert parts, multiaxial compression molding of fiber-reinforced thermoplastics, thermoforming, CNC gantry milling with clamping surfaces up to 2100 × 3700 mm, and additive manufacturing via Gsell 3D-Forming for CFRP instruments. Materials processed include PEEK, PPSU, PEI, implantable PEEK, fluoropolymers, thermosetting laminates (paper-based laminate MKHP, fabric laminates, mat laminates) and GRP profiles. Customers come from medical technology, plant and mechanical engineering, power distribution, generator and transformer construction, and railway technology. In addition to manufacturing, Gsell offers co-engineering and downstream processes such as cleaning, low-bioburden packaging in an ISO Class 8 cleanroom, marking, and assembly from a single source. In 2023, a sales location, Gsell Inc., was established in Maryland, USA.
