Plastic injection moulding

For the production of plastic injection moulded parts, we are at your service from the development of the respective injection moulded part - including the CAD construction based on your sketches or detailed 2D drawings - to the first prototype and serial production.

Project management

Our project management combines experience and professional competence with a structured, methodical approach. In practice this means: away from departmental thinking, towards simultaneous work, reduction of interfaces in order to pursue common goals in a concentrated manner and to achieve them effectively. We continuously structure and manage new product start-ups as a team.

Mould making

"A part is only as good as its mould."
Together with our partners, we develop, design and manufacture injection moulds using state-of-the-art computer technology.


Quality, adherence to delivery dates, value for money and customer care are essential factors for the satisfaction of our customers. This is one of the reasons why we make every effort to carry out your assembly professionally in-house and deliver the manufactured and assembled part to you free of defects.


Each machine is equipped with a touch screen. All important information about customers, product and the required quality can be called up in REAL TIME by every employee.

Prototype construction

Prototypes within the shortest time - functional prototypes facilitate the development work. Potential problems can also be identified early on. Together with our partners we offer a fast and economic production of prototypes and installable modules.
