Reliable manufacturing of preforms is the basis for high-quality composite leaf-spring components.
The key criteria for this are placement accuracy, system performance, and laying rate – all accompanied by high levels of process stability and system availability.
For this manufacturing technology, Fill has developed a flexible production cell for laying and preforming pre-impregnated composite materials (prepregs)
The priority here is maximum flexibility based on simple programming plus rapid component type changes, thereby guaranteeing constant capacity utilization of the machine.
From a roll of raw material, a linear unit removes individual strips in predefined lengths and places them on a provisioning table. From there, two robots grip the individual cuttings and manipulate them to the draping fixture, where they are laid down.
A pressure roller located on a third robot then executes the appropriate consolidation process.
Layer length and the number of layers are freely selectable and can be adjusted accordingly per spring, if required, due to an integrated weighing system in the draping fixture.
