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.

A brief introduction
We employ metal machinists, a shortage occupation in metal industry nowadays, who produce small series of special parts on traditional machines. In this sector CNC machines are so widely used that there is a shortage of traditional machines and excess demand exists for them. With this in mind, we will purchase several traditional machines during our current developments to increase our capacity in this field. We, of course, have CNC machines as well and develop our machine pool regularly. Based on the orders received, we are able to draw up a production program for 1 month in advance and allocate our resources. Our customers basically include producers which manufacture special purpose machines for their customers (e.g. manufacturers in printing industry, shipyards, industrial scale manufacturers, food producers, automotive industry, manufacturers of medical equipment), and we produce components needed for these machines. BAT tobacco factory is included among our customers, and we manufacture wear/consumable parts required for their daily production. We produce components and subassemblies for medical equipment manufactured by Siemens and GE factories. Besides, we supply units for robotic production lines of AUDI and VW factories.

The company had its first premises at the residence of the founders in Pécs. Production took place in a small workshop. At the beginning temporary workers were working in addition to a single permanent worker. The first orders we received involved simple processing of materials. In addition to manufacturing new products, we undertook and still undertake to carry out repair works. We undertook all works therefore outgrew the small workshop we used at the beginning, and in 2007 at Pécs-Hird we acquired our first production hall suitable for carrying out industrial activities with a floor space of approximately 250 m2. Here we were able to carry out production on a larger scale and serve more customers. Owing to our continuous progress and current developments, now the floor area of the production hall exceeds 1000 m2. Concerning work organization, our activities include manufacture and assembly of special-purpose products, machines and machine units. Therefore our machines and equipment are universal and able to satisfy all demands.
