the Airtech CATIA software or reverse-engineered off templates or handmade prototypes. As well as shaping materials, custom combinations can be produced: materials such as the peel ply and release film, or release film and infusion mesh, can be laminated together to provide a single product. This can then be applied more easily and faster onto the laminate, reducing operator labour during the moulding process.
Kitting of these pre-shaped and combined materials can provide even greater efficiencies in the moulding workshop. Material kits that include all the vacuum bag materials, delivered straight to the mould side, reduce time spent cutting roll stock and tailoring materials to fit the mould; these are already being employed in a variety of high-volume and large-scale moulding applications. n
The selection of the correct products is crucial to achieve reliable, cost-effective performance. Once this selection has been made, further economies can be achieved with the use of custom-engineered and kitted materials. Airtech provides a design and manufacture service for custom-made, shaped vacuum bags and resin infusion materials (see Figure 6). These can be cut to shape and even fabricated into three-dimensional shapes to suit the mould, thus lessening the time to apply vacuum bags by reducing tailoring and shaping by operators (see Figure 7). The design process can be done electronically with
