About KHI
KHI Kunstharz-Imprägnierung GmbH & Co. KG is a certified contract manufacturer in Neckarsulm with around 30 employees. The company impregnates castings with synthetic resin to seal porous components, primarily for sanitary and drinking-water fittings; the synthetic resin used, according to its KTW approval, is safe for food and drinking water. In addition, a downstream differential pressure test (leak testing) is offered. Since 2023/2024, the service portfolio, with the integrated KHI Metallbearbeitung GmbH & Co. KG, also includes sheet metal working with laser beam cutting, CNC punching and nibbling, press braking, and laser welding. KHI also offers laser cleaning, laser derusting and laser paint stripping as refurbishment processes, as well as surface finishing through galvanic zinc plating, anodizing and powder coating. The impregnation systems are PLC-controlled, with all relevant physical parameters monitored. Customers include, among others, the automotive supply industry and the sanitary sector.
