Suitable for all vacuum infusion processes, including:
Wind turbine blade manufacturing
Marine composite structures
Automotive composite components
Large-surface carbon-fiber parts
Industrial composite panels
RTM, VARTM, VARI, LRT and other infusion processes
During vacuum infusion:
The air extraction bag is placed over the laminate.
The flow media allows air to move quickly toward the vacuum outlet.
The VAP film regulates air evacuation, preventing resin channel marks.
Vacuum bag film maintains negative pressure.
Resin flows evenly without leaving indentations or defects.
The result is a stable vacuum environment and smooth, defect-free composite surface.
Compared with traditional manually assembled consumables:
Traditional Layup | Air Extraction Bag |
Multiple layers need cutting and fixing | Pre-assembled multi-layer design |
Higher labor time | 30–50% time saving |
Print-mark risk | No indentation |
Higher material cost | Lower overall cost |
Requires skilled operators | Easy for any operator |
A pre-assembled vacuum consumable used in composite vacuum infusion to ensure smooth airflow and high-quality
surface finish.
Up to 120°C, suitable for most vacuum infusion systems.
Yes. We support any length, width, or shape based on customer requirements.
Yes. The VAP film layer ensures zero indentation on the finished composite part.
Yes. Sample rolls or cut pieces are available upon request.
