The alternative – economic and environmental friendly fiRST® is the most recent closed mould technology providing rapid production of reusable silicon membrane B tool faces which also allow ease of manufacture for undercut designs (negative draft).

fiRST is todays proven alternative to costly one use consumable vacuum bags used in the composite moulding industry today.

Almost everyone will agree that there is a need to find an alternative to costly and wasteful consumable vacuum bags whilst still maintaining the flexibility of bagging film technology for infusion, pre preg and de baulk activities.

fiRST offers the solution in offering all that is needed to convert to a less wasteful and more economic reusable vacuum bag approach. A range of machines to spray manufacture the vacuum bags is offered to suite your budget.

fiRST system also offers a comprehensive range of vacuum bag accessories to ensure successful manufacture, vacuum secure and robust use of your bag.

After 42 years experience within the fibre composite moulding community involved specifically with environmentally safer closed mould production tooling the transition to a self releasing reusable vacuum bags became an obvious choice to develop. Based upon earlier rigid metal and composite moulds the fiRST system was proven to be the most economic solution to many of the earlier system drawbacks.

Vacuum bag moulds can be manufactured in a few hours and put into production the same day. If you are a moulder of composite parts for standard polyester frp components to advanced aerospace primary structures and wish to advance into a lower cost and cleaner production then fiRST is the way forward
