Plastic solutions for medical and pharmaceutical products

GEMÜ as an engineering and production partner

As a supplier to medical technology companies and pharmaceutical producers, GEMÜ Switzerland also produces customized plastic solutions for surgical instruments, lab accessories and other medical devices. Customers receive individual components, packaged and inspected assemblies and sterile finished products for immediate use in the medical industry.

Cleanroom injection moulding

The specialities of the efficient manufacturing plant are injection moulding of high-temperature plastics, integration of inserts and use of fibre-reinforced plastics.

Cleanroom assembly

Assembly is performed in accordance with the strict values of Class 6 as per ISO 14644-1. In high-purity environments, the washing, testing and packaging work is performed in parallel.

Plastics Engineering

We select the materials and produce the injection moulds, optimize designs and perform both rapid prototyping and process simulations for processing in cleanrooms.


Our new cleanroom makes it possible to produce ready-to-sterilize components with additional hygienic measures for the manufacturing cells. Plastics engineering
We select the materials and produce the injection moulds, optimize designs and perform both rapid prototyping and process simulations for processing in cleanrooms.

We develop, design and produce the injection moulds for plastic parts and for fluoropolymer processing. Any modifications to the mould are made directly in our Emmen factory.


Thanks to decades of experience, putting together mechanical and electronic assemblies has become one of our core skills. Plastic components can be manufactured without paint adhesion interfering substances.

Qualification and validation

GEMÜ drafts the risk assessment for your product. This includes investigating the system risks of the operating media and the process risks associated with manufacturing and we supply documented proof of this process.


Until they reach series production, medical systems projects at GEMÜ comprise the following five phases: Concept, product and process development, process proof and market launch.
