Vacuum Infusion Materials & Accessories

Vacuum infusion is a clean, efficient, and highly controlled process used in composite manufacturing to produce strong, lightweight parts with superior surface finish. It works by drawing resin into a dry fiber laminate under vacuum pressure, ensuring complete saturation and minimal air entrapment. Ideal for marine, automotive, aerospace, and industrial applications, vacuum infusion reduces waste and labor while improving structural integrity. To perform successful infusions, it’s essential to use reliable materials and equipment throughout the process—from surface preparation to final curing.

Advantages of Vacuum Infusion

Produces stronger, more consistent composite parts
Minimizes resin waste and reduces VOC emissions
Allows precise control over fiber-to-resin ratio

Enhances surface finish with fewer voids and defects
Ideal for large, complex, or high-performance components
Cleaner work environment and lower labor intensity

Peel Ply

Used as a release layer between laminate and breather.

Leaves a textured surface ideal for secondary bonding.

Bagging Films

Flexible films that create the vacuum envelope around the laminate.

Available in various widths and temperature ratings.

Perforated Release Film

Sits between laminate and breather to allow resin flow and venting.

Perforations control resin bleed and ensure uniform cure.

Bleeders / Breathers

Allow even vacuum distribution and absorb excess resin.

Essential for consistent pressure and resin flow.

Resin Flow Channels

Help distribute resin quickly and evenly through the laminate.

Includes mesh, spiral tubing, or flow media.

Sealant Tapes

Used to create an airtight seal between bagging film and tooling surface.

Remains flexible under vacuum and heat.

Adhesive Spray

Temporarily bonds dry fabrics or core materials in place before infusion.

Helps prevent shifting during layup or vacuum bagging.

Vacuum Accessories, Tubes & Connectors

Includes fittings, valves, vacuum lines, and connectors.

Designed for durable and leak-free connections.

Vacuum Equipment & Accessories

Pumps, gauges, catch pots, and regulators for precise vacuum control.

Critical for maintaining consistent vacuum during the entire process.
