Thermoplastic lightweight construction is up and comingThe FiberForm process also deals with processing thermoplastic matrix systems. FiberForm is the thermoforming and over-molding of organic sheets, platen-shaped semifinished products with continuous fibers made of glass, carbon or aramide that, for example, are embedded into a thermoplastic matrix made out of polyamide (PA) or polypropylene (PP). In this process, these semifinished products are first heated, reshaped in the injection mold and then back-injected with polymer, with or without fiber reinforcement.
- Since the market launch at the K 2010, we have consistently further developed the FiberForm technology, and today we offer our customers a series production solution - explains Stefan Fenske, FiberForm Technology Manager with KraussMaffei. New for the KraussMaffei FiberForm system is, for example, the concept of automation. The heating of the composite sheet and the demolding of the finished component take place in parallel, and the individual process steps are thus decoupled from one another. In addition, the infrared heating station required for heating up has been mounted directly above the mold parting line and - as a result - the transfer time of the composite sheet into the injection mold is reduced to a minimum. Overall, the FiberForm system provides its users with extremely robust processes, high availability and the efficiency required for high-volume series projects.
