About Fischer Söhne
Fischer Söhne AG is a Swiss plastics processor headquartered in Muri AG and has been manufacturing packaging and precision plastic parts for over 100 years. The company is one of the first addresses for complex plastic solutions from injection moulding, especially for the life science market, and one of the leading suppliers of plastic container solutions in the DACH region. Its core business comprises pharmaceutical packaging (tub & nest systems for pre-filled syringes), medical components (plunger rods, PE-UHMW implants), diagnostic containers as well as hazardous goods canisters and HDPE closures. Production is carried out with 23 injection moulding machines (30–500 t clamping force, several 500-t machines in the cleanroom) and 18 extrusion blow moulding machines in three cleanrooms certified to GMP Class C, ISO 7 and ISO 8. The services offered range from design and development through series production and assembly to logistics and warehousing services, including PET recycling. In 2025, the business division Fischer Söhne Extrusion AG was founded. Sales are conducted throughout Europe in German, English and French.
