About Plas-Tec
Plas-Tec Kunststofftechnik GmbH in Velbert specialises in the processing and fabrication of thermoplastics. Its focus is the manufacture of tanks (round tanks, rectangular tanks, cover hoods, containment tanks), pipework systems and apparatus as well as ventilation technology and food technology. In pipework construction, the company builds and installs plastic pipelines for industry, municipalities, utilities, the chemical industry and plant engineering – including for water, wastewater, gases, pipelines and district heating. For the food industry and catering sector, custom-made, HACCP-certified cutting blocks made of PE500 are produced. The manufacturing processes include hot gas speed welding, extrusion welding, heated-tool butt welding as well as machining (turning, milling, drilling, sawing, grinding); the company also offers design and assembly from a single source. As a certified specialist company under §19I of the Water Resources Act, Plas-Tec manufactures in accordance with DVS guidelines with internal production monitoring and regular inspection by TÜV-Nord. Thermoplastics processed include PE, PE-HD, PP, PVC, PVDF, PET, PMMA, PS, PA, PC and ABS.
