About HKT GmbH
HKT GmbH is a mid-sized company in Thimmendorf (Remptendorf), Thuringia, that has been engaged in the production of plastic parts for more than 25 years. Its core competence is extrusion blow molding: plastic hollow bodies with a volume of up to 150 liters are manufactured continuously and discontinuously using single and multi-cavity molds. The range of services includes development and design, prototype construction and sample optimization, as well as the implementation of tool concepts in cooperation with specialized mold-making partners. Downstream processing includes milling of defined connection dimensions, welding using heated tool or ultrasonics, trimming and punching, pad printing, and assembly into modules and shipping units including order picking and direct shipping to customers. The company produces technical plastic parts among others for the automotive industry, leisure, sports and toys, furniture, logistics and heating technology.
