Understanding Vacuum Bagging and Out-of-Autoclave Processes
The vacuum bagging process is one of the most popular processes for composites manufacturing. It involves using a vacuum bag to surround composite materials in a mold and compress them to ensure optimal resin infusion. Out-of-autoclave processes also involve the use of vacuum and pressure to achieve the desired infusion, but use methods other than placing the bagged mold into an autoclave, such as vacuum-assisted resin transfer molding or pressurized ovens
These processes are critical for modern composite manufacturing because they improve the overall quality of the laminate by ensuring optimal resin distribution and reducing the number of voids created by air pockets.
How Bagging Film Supports Closed Molding
The use of vacuum bagging film is critical for closed molding processes in composite manufacturing. By enveloping the entire mold and creating a tight seal around it, air can be removed from the inside. This means the film compresses the composites under intense pressure, ensuring a tighter bond between all the materials and eliminating any pockets of air that could create voids that weaken the overall structure.
Our lineup of process materials helps manufacturers ensure the highest levels of quality in their composite products. Aerovac vacuum bagging supplies deliver superior performance due to the strength and durability of the materials used which help prevent leaks and support a wide range of temperatures and pressures.
