Special-purpose machines, systems and contract manufacturing in machining and metalworking from one-off pieces to small batches
Maschinenbau Zenner GmbH
Rehlingen (DE)New on Amplifa
Everything from a single source
Maschinenbau Zenner GmbH is an owner-managed family business based in Rehlingen (Saarland) that has been developing and manufacturing special-purpose machines, systems, conveying technology, handling technology, smelting and rolling mill technology as well as assemblies since 1990. Its core competencies include custom solutions, contract manufacturing and services such as maintenance, preventive upkeep, assembly and repair – from one-off pieces to small batches. In its own metalworking shop, work is carried out using common welding processes (TIG, MIG, MAG, manual arc welding, gas welding) on Stellite, aluminium, copper, stainless steels and steel load-bearing structures. The machining division covers almost the entire range of metalworking with milling, turning, drilling, grinding and EDM. Customers come, among others, from the heat treatment, smelting and rolling mill industries, the automotive sector, plant engineering, the paper, food, chemical, glass and ceramics industries as well as mining. Design is carried out in AutoCAD, Inventor and Catia; the company accompanies projects from concept to commissioning and supplies customers worldwide.
