Vacuum Infusion is a term used to laminate the part dry, and then allow the resin to flow into the dry fibres.
These materials are generally normal vacuum materials, with a few differences. There is no requirement for a breather or release film, but an infusion mesh that transports the resin inside the bag to the dry fibres, as well a re-usable silicone infusion track that disperses the resin. This is a simple process once you get the gist of it, but there are very definite considerations when laminating with core for example.
We will gladly assist in the planning of the infusion process and the placing of the various materials.
