Vacuum Infusion Process (VIP)

Vacuum Infusion is a closed mould process. Atmospheric pressure is used to push the resin into the mould cavity.

With vacuum infusion, the production process is highly controllable. This results in very consistent product quality. Another advantage (like for all closed mould production technologies) is a minimal styrene emission.

By applying vacuum, resin is sucked up into the laminate via carefully placed tubing. The composition and the temperature of the resin are essential in achieving good results. Vacuum Infusion provides an excellent glass-to-resin ratio with minimal to no voids in the finished laminate. 

At the same time, VIP requires substantial manual labor in order to complete a production cycle. Rotec uses VIP for the production of complex, three dimensional shapes like saddles, elbows, panels and various customer specific products.
