About Angehrn AG Umformtechnik
Angehrn AG Umformtechnik in Degersheim is a Swiss manufacturer specialising in drop forging and hot pressing of high-strength structural components. From steel alloys, rust- and acid-resistant stainless steels and titanium, the company produces precision parts with piece weights ranging from a few grams to around 10 kg (titanium up to approx. 1 kg). The value chain includes, in addition to hot pressing, in-house heat treatment, toolmaking, raw material cutting and mechanical finishing by drilling, milling, grinding, polishing, deburring and cleaning. In addition, purchased parts are procured and ready-to-install, function-tested assemblies are assembled. Customers come from general mechanical engineering, medical technology (medical implants), pressure equipment manufacturing and rail infrastructure, including HPQ qualification for Deutsche Bahn. From a locksmith's shop founded in 1907, an internationally active company has evolved that delivers its products worldwide by truck, rail, ship or air freight.
