Gronbach has been developing and producing components and complex assemblies on a production area of over 20,000 m2 with 290 employees since 1964 and has also specialised in the processing of stainless steel and aluminium, surface finishing and plastic injection moulding. In addition, a separate department is dedicated to the development of new surface technologies, manufacturing and assembly processes.

The core competencies of the Wasserburg site are in the following areas:
Metal processing (bending, milling, deep drawing, drilling etc.)
Surfaces (anodising, powder coating, printing, laser engraving)
Plastics technology (hybrid, back-moulding)
hybrids
instrument engineering
development work

PRODUCTION TECHNOLOGIES AND PROCESSES

In the area of production technologies, we have specialized primarily in the surface refinement of stainless steel and aluminum, the production of functional and visible components as well as plastic injection molding and adhesive technology. These technologies form the basis of our equipment technology, but are also offered by us as individual services.

We are constantly expanding and renewing our portfolio with new combinations of technologies and materials, e.g. in the art of back-moulding metals such as aluminium and stainless steel with different plastics, in order to be able to offer our customers high-quality and cost-optimised manufacturing processes.

Reuse of existing and proven machine tools up to complete production systems - through conversion, automation, overhaul, maintenance and relocation.

GTK-Prototype UG was founded in 2014 by Tobias Günther and initially dealt with rapid prototyping machines.

Over the years, CNC milling and turning as well as assembly and development work were added due to customer requirements.

GTK-Prototype develops and designs on behalf of customers as well as internally using the most modern CAD systems such as Solid Works, Autodesk Inventor, Fusion 360 and others and inserts them into a comprehensive CAM system.
Through the production of prototypes in medical technology, mechanical engineering and the automotive sector, GTK-Prototype was able to acquire extensive experience in manufacturing.

In 2018, the production option laser cutting was added.

GTK-Prototype is currently based in Neuhausen near Tuttlingen and will move to the newly built company location in Radolfzell in the course of 2022.

Re-discover steel at PETRI!

Our story began in 1874 with the establishment of a trade company for steel. Crises, wars and economic miracles led to many highs and lows. But - then as it is now - working with metals is our unbroken passion. Customer focus and flexibility have always distinguished Gustav Petri & Co over the years.

In the 80s, our focus shifted to the machine processing of metals. Modern machinery was setup gradually, with which we meet the high demands of our clients every day.

Gustav Petri & Co. is now managed by the 3rd generation, Mr. Johannes Huber. Many well-known clients of the industry and trade see in him and in his capable team, a reliable, flexible and solution-oriented partner.

In recent years, we have managed to add another pillar to our business with the development and production of storage systems for wood pellets. By consistently developing these and other proprietary products, we see the possibility of demonstrating our expertise and quality far beyond the borders of Austria.

In 1992, the Diakonisches Werk Mecklenburg-Vorpommern eV and the former districts of Güstrow and Teterow merged to form our non-profit limited company.

We also have a Mazak Integrex 300 IV S multitask machine, so that we are able to high-precision workpieces of 6 Pages to machine in one clamping.
Main passage, and counter spindle 77mm. Turning diameter max. 760mm x 1000mm in length.

In the milling area 13 CNC machines are six of machining centers in the area
to 1200x650x600mm available. Weitehin two Mazak VTC BAZ 300 with the CII processing mass X 1744, Y 760, Z 660 mm. The work area is divided for pendulum machining.

For quality assurance, we are two CNC 3-D measuring machines, a 2-D height gauge and a NC-meter contours are available.

Our machinery is supplemented by a variety of conventional machines for turning, milling, drilling, tapping and grinding. Also, assembly and surface treatments and hardening processes are part of our range of services.
