“ALL TOOLING IS DESIGNED IN-HOUSE”
Mould tooling is designed and generally manufactured on site. For Hand Layup, Spray Layup, and RTML the mould tools are typically a composite of either vinyl ester/polyester and glass fibres, or epoxy and glass fibres. Depending on volume, it may be economical to use metal tooling, either machined or metal faced.
Where very short lead times are required, prototype tooling may be CNC machined directly from foamed polyurethane block. This type of tooling may be re-machined where modifications become necessary during development.
Composite mould tooling would be moulded directly from a Master Model or Pattern. The master model or pattern would normally be in a positive form, and may be produced manually from engineering drawings or CNC machined from Pu foam block. For Low Pressure Press Moulding, or RTM the mould tools would be metal faced (nickel shell), or CNC machined from metal billet. In either case, the CNC cutter path would be generated directly from the CAD data.
Robotic Trimming Fixtures consist of a composite skin attached to a support structure, which forms the interface with the robotic trimming centre. For low volumes, assembly fixtures may be manufactured from a combination of composite and steel. For higher volumes, or where a high degree of accuracy is required, fabricated/machined steel or aluminium is preferred.
