About thermoPre ENGINEERING
thermoPre ENGINEERING GmbH, based in Chemnitz, is a full-service provider for thermoplastic composites (fibre-reinforced plastics, FRP). The company supports projects from the initial idea through technology development to implementation for series production. The service portfolio includes the design and dimensioning of FRP components, calculation and FEM simulation, material data sheets and material characterisation, tool design, the development and production of load-adapted semi-finished products (UD tapes, organic sheets, hybrid rovings, GMT, LFRT) as well as component development including the process chain, component testing, prototypes and pre-series products. Manufacturing processes used include thermoforming, injection moulding (including in-mould, multi-component and foam injection moulding) as well as pressing processes with thermoplastic FRP and rapid prototyping. In addition, the company offers recycling of thermoplastics with and without fibre reinforcement as well as technical elastomers, and material functionalisation. Customers include the automotive and special-purpose vehicle industry (ambulance and rescue vehicles) and e-mobility; reference projects have been realised with MAHLE Group and Ambulanz Mobile GmbH & Co. KG. The team consists of graduate engineers with many years of experience in calculation, simulation, dimensioning as well as semi-finished product and process development.
