Vacuum Infusion Process

Vacuum Infusion Process (VIP) produces high quality, consistent parts for demanding applications.
Like other closed mold processes, VIP uses a rigid “A” side base mold, but unlike other processes, it uses a thin bagging film being as the “B” side or counter mold. Specialty reinforcements are laid into the base mold, followed by release film or peel ply, flow media, nd resin and vacuum lines. Bagging film sealed onto the base mold. A vacuum is pulled through ports in the bagging film and catalyzed resin is pulled into the mold cavity using only vacuum.

This process is highly controllable because it’s governed by the principles of D’Arcy’s law, meaning there are three variables that affect the flow of the resin: permeability of the reinforcement construction, viscosity of the resin, and the pressure differential in the cavity in relation to atmospheric pressure.
