CLASSIC INFUSION | RFI
The infusion of composite materials (VIP – vacuum infusion process) is a production process more and more used to improve the aesthetic quality of the final product and to reduce the total labor costs. The resin infusion system primarily provides a process, held under vacuum, in which the suction pump creates a depression that pushes the catalysed resin to impregnate and pass through all the layers of tissue. The speed with which it can fill a stack of tissues depends on the viscosity of the resin system, by the permeability of the fabric layers and by the pressure gradient acting on the resin infused. This process primarily involves the use of vacuum bags in the film, however, the market today also offers an alternative to in reusable silicone vacuum bag for longer printed. The infusion with resin film differs from the classical one in the machining process; in fact it provides for a processing system in which a subject at different temperatures resin film is placed over the fabric and, thanks to the vacuum created by the pump, it passes through all the layers of the fabric in a uniform manner. The advantages of using the RFI system compared to traditional, consist in a costs saving, in a more rapid and efficient production and a higher accuracy in the realization of the final product.
