About Kalmbach Technologie
Kalmbach Technologie e.K. is an owner-managed CNC manufacturing company in Tübingen-Pfrondorf. The company manufactures milled parts on 3-axis and 5-axis machining centers with component dimensions up to 3000 mm in length and 1600 mm in width, maintaining tolerances according to IT7, partly IT6. The material range includes aluminum, steel, stainless steel, brass, copper, titanium, and engineering plastics such as POM and PE. Furthermore, the service offering includes complete mold construction for particle foam (EPP, EPE, EPS), carbon, and wax injection molds, including design, CAD programming, and assembly. Production starts from 1 piece and caters to prototype and development departments, special machinery engineering, mechanical and plant engineering, plastic processing, the automotive industry, electronics, and medical technology. Surface treatment such as anodizing, powder coating, hard coating, or laser engraving is carried out by proven partner companies. Quality is documented on a TESA 3D coordinate measuring machine in the hundredth-millimeter range; the company is certified according to ISO 9001.
