Vacuum Infusion
Closed-mold process in which resin is drawn through fiber reinforcements under vacuum. This method stands out for its excellent mechanical properties and strong lightweight design potential, while also offering a reduced environmental footprint.
Infusion Process
The Steps
Gelcoat Application
Liquid gelcoat is sprayed into the mold
Fiber Layer Placement
Fiber layers are placed in the mold to form the future part
Placement of Infusion Elements
Compaction and flow media are installed to compress the fibers and allow the resin to flow through the laminate
Resin Infusion into the Part
Resin is drawn through the fiber layers under vacuum to impregnate the laminate
Resin Curing
A chemical reaction converts the resin from a liquid to a solid state
Part Demolding and Removal of Infusion Elements
The finished part is removed from the mold and the infusion materials are removed
