Krauss Maffei of Munich Germany, recently demonstrated the power of their machinery by producing airbag housings made of thermoplastic composites in a production cell combining a CX 300-1400 injection moulding machine with a LRX linear robot at the Plastimagen Expo that was held in Mexico in November.
A CX 300-1400 produced airbag housings made of fibreglass-reinforced polyamide with a shot weight of 350g in a cycle time of 45 seconds. The housing is 40% lighter than conventional components made of metal, does not have to be reworked and is ready to install imediately.
The demonstration showed the utilization of the FibreForm process, a combination of injection moulding and thermoforming of composite sheets. The combination of lightweight materials and design in the construction enables new fibre-reinforced lightweight thermoplastic components to be manufactured with particularly high strength. In the process, endless fibre fabric or textiles impregnated with a thermoplastic matrix are heated, then shaped in the injection mould and finally over-moulded. This allows ribs to be added for extra stiffness and other functions and fitment features to be integrated into the part.
"In Mexico we are finding an increasing demand for cost-effective lightweight construction solutions, especially for the automotive and transport sector" said Emilio Lopez, Krauss Maffei Group Mexico. "Krauss can precisely meet the requirements of these customers".
