Vacuum Infusion Process
SHORTCOMINGS OF VIP
Most of the disadvantages of vacuum infusion are linked to the process’s long set-up time and general handling. Unlike hand lamination, vacuum resin infusion requires one to strategize and develop the optimal vacuum ports and resin injection locations for each composite that is made.
Furthermore, it also requires an experienced hand and can become expensive if there are continuous vacuum leaks as the entire part will have to be binned. Its cosmetic finish is also not as good as open mold processes due to the fabric print; however, this can be amended using a barrier coat.
At this stage of the process’s development, vacuum infusion is more suited to smaller projects. Too much time is required for applications that need high production rates or more complex processes on a mass scale. This is especially true when multiple-use flexible films or top molds are needed for one-off or large parts.
