Vacuum Bagging

Sino Composite, the forerunner that introduces vacuum resin infusion process (VRIP) into the Chinese composite market, has developed itself into a comprehensive solution provider of vacuum bagging in aerospace, wind energy, marine and sports equipment, etc.With its whole series of vacuum bagging products with all temperature rangas well as the full-scale technical training and onsite support.

Vacuum Bagging Process

Vacuum Bagging is a technique that imposes vacuum pressure to the surface of the object between the mouldtooland the vacuum bag to optimize the fiber-to-resin ratio of the product. Therefore, it can improve the mechanical performance of the product.

 

Usually, the vacuum bagging process canbe classified as two types:

1. Vacuum bagging for resin infusion. Infuse the resin to dry preform of fabrics layers with a stable pressure.

2. Vacuum bagging for prepreg or wet lay-up Impose vacuum pressure onfabricsimpregnated with resin.
