About us
As an established family-owned company from the Black Forest, Weißer + Grießhaber combines decades of experience with innovative power. We have grown into a reliable partner for companies from around the world that rely on the highest standards. Our world is plastics technology. You can feel it in every detail – through precision, performance, and our will to find the perfect solution. Martin Weißer represents his family’s third generation in management of the company from the Black Forest.

We have been manufacturing sophisticated plastic injection-moulded parts since 1969. We have become a series supplier with our own mould-making facilities. Our particular strength lies in the production of high-precision plastic parts for a wide range of markets – from automotive and building technology to automation and medical technology. These include gearing and transmission parts, complex multi-component injection moulded parts, micro injection moulding, and optical-functional components. Our development and production solutions are always created in close cooperation with our customers. Transparent communication, fixed contacts, and customised supply chain concepts ensure reliable results – from application development to series production. Our mission is: Excellence in plastics
We see plastics technology as an integrated process – from development and mould construction to large-scale production. We ensure precision, efficiency, and process reliability with a high degree of automation, digital project management, and AI-supported production processes. We always remain at the forefront of technology by using cutting-edge software, simulations, and close cooperation with technology partners.

Diversity
Diversity is our strength.
Our ideas are as diverse as the people who develop them. We believe that different perspectives and personalities help moving us forward – as a team, as a company, and as an employer. We leave no space for discrimination. We do not use any special characters in the language to improve legibility. We strive to fill our vacancies with people, rather than labels. We see you as a person – not as an identity.
