Bond-Laminates is exhibiting new applications for its Tepex range of continuous fibre reinforced thermoplastic composites at JEC World.
“At the world’s leading composites trade fair, we’re looking to highlight the opportunities offered by Tepex semi-finished composites in large-scale series production of components in terms of their mechanical properties and optical performance. This applies in particular to hybrid moulding, which combines forming of semi-finished products with injection moulding,” says Jochen Bauder, Managing Director of Bond-Laminates.
In hybrid moulding, Bond-Laminates says that semi-finished composites are both formed and over-moulded in an automated one shot process in the injection mould, thus shortening the production process. The investment costs are also cut by eliminating the forming tool. The result is precision 3D components in highly reproducible quality that do not require reworking and directly integrate functions such as fixings and guides. “The cycle times for this reliable and stable production process are now 60 seconds and less, which also facilitates cost-effective large-scale series production of complex components,” says Bauder.
At the Brilon site, Bond-Laminates has installed a demonstration cell for fully automated processing of Tepex using hybrid moulding, among other things. “We use this to support customers in developing production-ready prototypes,” says Bauder.
Bond-Laminates says it is able to simulate all hybrid moulding process steps, whether these concern the draping of the semi-finished composite or mould filling in over-moulding the formed insert. “Starting with the local fibre alignments in the formed semi-finished product that result from the draping simulation, we can also calculate a component’s mechanical properties precisely and adapt the design to the load scenario accordingly,” says Bauder. Bond-Laminates claims these integrative calculation tools have already proven their reliability and precision for numerous prototype and series components.
Hybrid moulding with Tepex semi-finished composites is not just suitable for manufacturing structural components that are hidden from view, such as front ends, brake pedals and seat shells. Bond-Laminates explains that it also comes into its own for visible applications, including electronic housings and sports equipment components, that need to look good. Variothermal mould temperature control delivers surface quality that meets demanding requirements. “This will be on show at our stand in Paris using a demonstration model that will also highlight the design options that Tepex opens up in hybrid moulding,” says Bauder.
At JEC, Bond-Laminates is showcasing highly integrated, crash-resistant seating shells from a German sports car and a ski binding as examples of cost-effective series-produced structural components using hybrid moulding. “To clearly explain the automated hybrid moulding process to our customers, we’re presenting videos covering the series production of various components at the trade fair,” says Bauder.
