About Manthei Zerspanungstechnik
Manthei Zerspanungstechnik GmbH was founded in 1990 as Bernd Manthei Zerspanungstechnik GmbH + Co. KG and is a contract manufacturing company based in Dautphetal. The company with 19 employees produces turned parts, milled components including 3D HSC milling technology, and deep-hole drilled parts. The service portfolio also includes welded fabrications up to 12 t using MIG/MAG, TIG and stick welding, annealing, sandblasting and mechanical machining. With a machine park of 5-axis machining centres, HSC milling machines, CNC lathes and deep-hole drilling machines, the company covers single-part and large-series production. Its manufacturing depth is oriented towards mould and tool making (die casting, injection moulding, permanent mould casting), mechanical and plant engineering, prototype tool making and forming technology. Customers come from the automotive and automotive supply industries, special machinery construction, the gas industry, sheet metal forming, the steel and foundry industries and the consumer goods industry. Quality and accuracy are assured by 3D metrology with GOM systems; the company is certified to ISO 9001 and ISO 14001.

Quality and Certification
Quality assurance is carried out, among other things, through 3D metrology: With the GOM ATOS III 400 and a 3D measuring machine (Zett-Mess, PowerInspect software), tools and components are compared with CAD or drawing data or digital copies are reconstructed. The quality and environmental management system is certified to ISO 9001:2015 and ISO 14001:2015 (BSI).
