Complex Geometries: Easily manufacture intricate, complex shapes, unlocking new design possibilities.

Environmentally Friendly: Minimize resin waste and emissions, making vacuum infusion molding a sustainable choice.

Vacuum Infusion Molding Process

This process can be introduced to a molding shop with minimum investment. Existing open molds can be used with little or no modification, and the process is adaptable to large or small components. In the Vacuum Infusion Molding process, dry reinforcements are encapsulated between a rigid, airtight mold and a flexible membrane (vacuum film or ‘bag’) which is sealed around the edge of the mold. This forms a cavity which is then placed under vacuum to compact the reinforcement.

Catalyzed resin is introduced into the cavity and the vacuum pulls it through the reinforcement. Once the component is fully infused through the material, it cures. after which the bag and the component are removed from the mold.

Resins for use in the Vacuum Infusion Molding process need to be low in viscosity and may also require controlled exothermic properties, for larger sections or thicker components. There are several variants of the Vacuum Infusion Molding process.

Closed Mold Vacuum Infusion

Introduce vacuum infusion molding to your shop with minimal investment. Existing closed molds can be used with little or no modification, making this process adaptable for both large and small components.

The Closed Mold Vacuum Infusion Process

1. Layup: Dry reinforcements are placed within a closed, airtight mold.
2. Bagging: A vacuum film or 'bag' seals the mold's edge, creating a cavity.
3. Resin Infusion: Catalyzed resin is introduced into the cavity, pulled through the reinforcements by vacuum.
4. Curing: After full infusion, the component cures, and the bag and part are removed from the mold.

Key Considerations for Vacuum Infusion

Resins used in vacuum infusion should have low viscosity and may require controlled exotherm properties for larger or thicker components.
