About La Plast
La Plast is a company specialising in plastic piping construction (tuyauterie) and plastic vessel fabrication (chaudronnerie plastique), based in Bex in the canton of Vaud. The company supports industrial businesses in Switzerland throughout the entire life cycle of their plastic installations: from 3D design and technical validation, through the manufacture of custom-made components, to on-site installation, maintenance, repair and a 24/7 emergency service. Products are made from thermoplastic materials such as HDPE, PVC-U and PVDF, including pipes, valves, check valves, fittings and special components. Various plastic welding processes are used, including butt welding, infrared welding, extrusion welding, hot-air welding and electrofusion welding. The company is approved for work on drinking water networks (VKR certification) and serves industries such as chemicals, pharmaceuticals, civil engineering and agri-food. La Plast operates throughout French-speaking Switzerland (Romandie).
