What we do - Vacuum Infusion Experts

At NZ Composite Tech Ltd we utilise both the closed moulding technique, otherwise known as vacuum infusion and wet lay up in our work in repairs, restoration, manufacturing and production.

Why use vacuum infusion?

Vacuum infusion produces superior fibre resin ratio which gives the product light weight, durability, strength but at the same time, flexibility without causing any cracking.  Another advantage of using this method is that vacuum infusion is a cleaner form of production in terms of fumes and is seen as environmentally healthy.  Finished products using this method can be seen on the aviation and marine pages.

Wet lay up is used for smaller jobs, and in mould production it is used as first layers against tooling gel coat.  We manually use rollers with fibreglass, and resin is impregnated into the fibres.  Laminates are then left to cure at the required temperature.  Wet lay up provides solid structural properties with a good resin to fibre ratio. 

For the manufacturing of moulds, for any products we use wet lay up in conjunction with vacuum infusion.   After tooling gel coat is applied onto plug, the first 3 layers are then laminated by hand using wet lay up.  The rest of the laminate is completed using vacuum infusion.  This method reduces the possibility of ‘shrinkage’ and mismatch, when double moulding is required.  Therefore, the product ends up with minimal seams, which in turn reduces the time needed in post-production.
