Compactors and Laminators function by passing a material substrate (paper, film, fibre, fabric) through a set of rotating rolls. Control of the gap between the rolls and the subsequent pressure imparted to the substrate is key to the function of the compactor or laminator. Often an additional material, such as resin, is added to the substrate prior to the substrate passing through the compactor or laminator.
Compactors are frequently used in high end pre-preg systems. The compactor is the heart of the pre-preg machine and is the key to it’s success for impregnating resin into the dry fibre/fabric, generating the B-stage material and achieving an optimum surface finish.
Compactors used in pre-preg systems generally have:
