About Karl Pfestorf
Karl Pfestorf GmbH Präzisionsteile manufactures highly precise turned parts, parts, products and assemblies in Zella-Mehlis on the edge of the Thuringian Forest for technology-intensive industries. Core competencies are short turning up to 700 mm working length and 80 mm bar passage, long turning up to 205 mm working length or part lengths up to 2.000 mm, and chuck-turned parts up to Ø 205 mm. Production takes place on modern CNC lathes with up to three turrets, driven tools and main and counter spindle in non-ferrous metals, plastics and all grades of steel. As a full-line supplier, the company accompanies the process from CAD design through machining to post-processing with drilling, thread rolling, press and punching work, welding (MIG/MAG/WIG/spot), assembly, cleaning and preservation; surface coating and heat treatment are carried out in cooperation. Customers come from mechanical engineering and industry, automotive, transportation, medical technology, apparatus engineering, the fittings industry and office furniture manufacturing in Germany and abroad, including Adtran Networks, Alstom, Continental and Grammer. On 4.200 m² of production floor space, the company combines 100 years of tradition with CNC technology and Thuringian master craftsmanship.
