KET Kunststoff- und Elasttechnik

What KET Kunststoff- und Elasttechnik does

KET Kunststoff- und Elasttechnik GmbH is a privately-held German injection molding manufacturer founded in 1904, headquartered at Wachauer Str. 3 in Radeberg, Saxony. The company produces custom molded parts from silicone (including LSR and HTV), plastic, and rubber/elastomers, operating an extensive machine park with clamping forces from 250 to 4000 tons capable of producing parts from 0.4 grams to 6000 grams. KET serves large industrial customers across medium and high voltage electrical engineering, automotive, mechanical and plant engineering, medical technology, and food and beverage sectors. Its technology base includes a patented in-house series system for wound grid production from liquid silicone using plotter-based additive manufacturing (annual output of 10,000 sqm, up to 3 million serial pieces), Class D clean rooms per DIN ISO 14644, and CAD-based development supporting DXF, DWG, IGES, STL, and STEP formats.

The company is positioned as a system partner offering complete solutions from early-phase product and process development through tool construction to serial production. Revenue is generated primarily through direct B2B sales of custom molded parts (one-off and ongoing supply) and contract manufacturing services, priced via quotes against customer specifications under EX Works (Incotoms 2020) terms with 14-day payment for regular business customers. The company holds DIN EN ISO 9001:2015 and DIN EN ISO 13485:2016 AC:2017 certifications and is authorized to manufacture Class 1 sterile and Class 2a medical devices under the Medical Devices Act. Distribution is exclusively direct B2B with no retail, e-commerce, or marketplace channels; geographic scope is concentrated in Germany. Recent strategic activity has centered on machine park expansion (Maplan MBF 3500/300 in 2020, DESMA 968.400 ZO B750 in 2021), a recycled-rubber product line launched in 2021, and an energy-efficiency capex project with a KraussMaffei KM160-750CX supported by a 120,888.60 EUR Saxon state grant (SMEKUL) in 2026. The managing director is Gunter Böttcher; the company is independent with no disclosed parent or external investor.
