We have a nice big CNC machine, up to 7000x3000x1800mm.
Matched mould and core cutting for high tolerance laminating.
Can also cut stainless plate.
METHOD 1. Cutting a smooth foam plug (1-2mm undersize) and sparaying with a tooling compound for a hard surface (1-2mm thick) this is the easiest method but wil need light rubbing back with 600 grit onwards. About £1000
and 24 to 48 hour turnaround.
METHOD 2 cutting a foam, coating in class layer, filler layer then a thick tooling compound while still locked down in the machine, curing then re machining to what ever resolution (the passes are kinda like a bubble jet printer resolution) though any finer than 1mm stepover with a ballnose cutter is silly (results in surface ripple deviation of less than .06mm.) About £3000. Good for direct moulds and vacbag production. Also good for parts that need to mechanicaly fit with others, also closed mould and infusion mould.
I have simplified CNC foil cutting costs following lots of email enquiries, so people can easily work out prices.
£80 per 1000 square cm (thats both sided not per side), sanded and ready to glass. So a foil 1.1m long 17cm chord would be £ 149.60
you supply core.
If you are laminating core try make one side smooth so i can clamp it down flat.
Extra identical foils cut at the same time are 40% discount.
