From the mechanical processing of individual parts to plant and mechanical engineering - our wide range of services offers tailor-made solutions for every requirement. Our customers come from medical technology, environmental technology, the printed circuit board industry and the semiconductor industry. Wherever absolute purity and precise solutions are required, the G-Werk 5 supplies the appropriate product solution. 


plastic processing

The foundation of our range of services is the mechanical processing of all plastics. In addition to the commonly processed plastics such as PE, PP and PVC, high-performance plastics such as PVDF, PFA, PC glass, PVC transparent, PTFE, PEEK or ECTFE are also processed. 

With the help of the versatile machine park, complex milled parts, turned parts and transparent bent parts can be manufactured. The basis is the customer specification or drawing. We work closely with our customers to understand their requirements and needs and offer tailored solutions, ensuring the highest quality and on-time delivery.

Manufacturing of plastic assemblies

Plastic welding is at the heart of our production. Customized plastic assemblies are developed and designed together with the customer and then produced in-house with the highest quality standards. 

We will professionally mill, saw, weld and assemble your assembly from the prototype to the series product. In the interest of the customer, production processes are optimized and costs reduced as a result of simple and at the same time technically outstanding solutions. The aim is to build up a long-term and trusting cooperation with our customers.

From small devices to systems

In addition to the production of individual plastic assemblies, our range of services also includes the assembly of entire complex devices. These range, for example, from small devices such as a chemical supply cabinet to ready-to-connect disposal systems for biological waste.


In addition to technical advice during the entire production process, the focus is also on commissioning and subsequent on-site service at the end customer. We understand the high demands and standards required in our customers' industries and strive to meet those requirements. Our goal is to offer our customers tailor-made solutions that guarantee the highest quality and delivery reliability, regardless of whether it is a question of small devices or complex systems.
