PIAG helps you with development and prototyping. You have an idea or need a tool, a device or an adaptation of a device for your application. We develop and manufacture the necessary components for you.

With our precision engineering workshop, equipped with two CNC-controlled milling centres and lathes each, as well as the necessary tools and clamping facilities, we can manufacture almost any part for you. If necessary, we design and draw the part in advance on our 3-D CAD system.

As an equipment manufacturer, you are still looking for a partner for the development and manufacture of individual assemblies. Or you have all the assemblies, but still need to place them in a cost-effective, service-friendly housing with a good design. If you wish, we can also carry out the final assembly with certificates right here at our premises.

Some examples of our work

OEM assembly

For manufacturers of larger systems we develop and produce assemblies such as drive units, damping elements, housing groups, etc. For these OEM (Original Equipment Manufacturing) applications, we put all our know-how to work for you. Take advantage of our experience in the production of your devices and systems (cost optimisation, planning, QA).


We make adjustments and modifications to existing equipment and systems from all manufacturers so that they fully meet your requirements.
