Vacuum Bagging Supplies

Gathering vacuum bagging supplies is the first step in this innovative clamping system for laminating a wide range of fabrics, core materials, and veneers with epoxy.

Vacuum bagging uses atmospheric pressure to deliver firm, even clamping pressure over the entire surface area of a composite part or repair, regardless of the material or materials being laminated. By laminating over simple moulds, composites can be moulded into an endless variety of functional shapes.
