About Lapp Engineering AG
Lapp Engineering AG is a Swiss specialist in polymer technology based in Cham. The company develops custom compounds according to customer specifications – as a rule without financial risk for the customer. In its own technical center and laboratory, formulations are developed, test blends (granulate) are produced on in-house compounding equipment, and 10 to 100 test specimens per formulation are manufactured by injection molding, extrusion or pressing. Mechanical and project-specific testing takes place in the company's own testing laboratory. Quantities up to sample batches of around 25 kg are compounded on the company's own equipment; larger quantities are produced by qualified contract compounders on an industrial scale. The service portfolio includes material development, prototyping and pre-production, process engineering support in customer production, series material supply, and patent management (intellectual property). The services of the material development stage are generally free of charge for customers.
