About OTM Metallwaren GmbH
OTM Metallwaren GmbH was founded in 1990 as Ostthüringer Metallwaren GmbH in Zeulenroda-Triebes and today manufactures metallic precision parts and assemblies for all industries. Its range of services includes CNC turning and CNC milling, laser cutting and CNC sheet bending, CNC sawing, pressing, stamping and deep drawing, tube processing and tube forming, welding (MAG, TIG, spot welding, stud welding) as well as high-temperature brazing of stainless steel under shielding gas with hydrogen shielding gas in the belt brazing furnace. In addition, the company offers its own toolmaking for stamping, deep-drawing and bending tools, cleaning processes such as tumble finishing and ultrasonic cleaning, and pre-assembly of assemblies. Surface finishing such as zinc plating, powder coating or anodizing is carried out with long-standing cooperation partners. Its approximately 55 employees supply, among others, mechanical and plant engineering, medical technology, the lighting and furniture industries, and stove and fireplace construction.
