Closed Mold Processes are Used to Manufacture Products Made from Corrosion-Resistant Composites

Composite materials are replacing traditional materials such as wood and steel due to their corrosion-resistant properties. Industries, such as the corrosion industry, that often-subject equipment to harsh environmental elements and chemicals require material that can withstand the corrosive nature of the elements without losing strength or structural integrity.

Closed mold processes are an efficient way to manufacture corrosion-resistant products. Specifically, Vacuum Infusion Processing can be used as a cost-effective method to manufacture corrosion-resistant composites at a high quality.


What are the advantages of Vacuum Infusion Processing for composites?

Vacuum Infusion Processing is a type of closed mold process that requires the resin to be poured into a vacuum-sealed bag where it will take the shape of the mold. You can read through the exact process here.

There are many advantages of using the Vacuum Infusion Process to manufacture corrosion-resistant composite products. One such advantage is that this process provides a standardized bill of material due to the constant flow of the process. The fiberglass and resin usage remain the same throughout the process unless one of the process variables, such as the permeability of the reinforcement construction, viscosity of the resin or the pressure differential in the cavity is changed. It also features a good glass-to-resin ratio with limited-to-no voids in the finished product.

Another advantage of using Vacuum Infusion Processing for composites manufacturing is the minimal styrene emissions that negatively impact the environment. Because this process is closed mold, the emissions are reduced significantly compared to some open mold processes.
