- **Rapid Production**: You can calibrate and spray up a reusable 2 m² closed B mould membrane in the morning and put it into production in the afternoon of the same day. In contrast, for RTM or LRTM, it typically takes at least three days to reach such potential, particularly for production injection moulding.

- **Versatile Moulding**: Reusable membrane moulds can effectively mould all types of undercut product features. For RTM or LRTM, considering undercut part geometry is often impractical or uneconomical.

- **Cost Efficiency**: When comparing traditional single-use vacuum bags to reusable membrane bags, reusable vacuum membranes transform a "consumable expense" into a "capital asset."

These advantages highlight the efficiency and economic benefits of adopting reusable closed mould technology in composite part production.
