About KRONTEC
KRONTEC Maschinenbau GmbH, based in Obertraubling near Regensburg, specializes in pneumatic and hydraulic systems as well as multi-axis precision turned and milled parts for customers from motorsport, automotive, medical engineering and aerospace. The product portfolio includes pneumatic air jacks for pit stops, hydraulic quick-disconnect and refueling couplings, steering wheel quick releases as well as custom-designed tube and hose systems in lightweight construction. Parts are manufactured from aluminum (including 7075), stainless steel, titanium and high-quality plastics such as PTFE. Around 95% of value creation takes place in-house: CNC turning and milling up to 5-axis simultaneous machining, CNC tube bending, soldering, assembly, in-house electroplating as well as comprehensive quality assurance including 100% pressure testing of every line. Customers are leading automotive manufacturers and racing teams worldwide – from Formula 1 to WRC, DTM and GT to Superbike. The shipping focus is Europe; products are delivered worldwide to more than 30 countries via the sales office in Swindon (UK). All customer-specific products are manufactured at the Obertraubling site.
