(1) Hollow 3D Airbags: This airbag comprises primarily polyamide and release materials. The prepreg is applied directly onto the airbag and placed into a shaped mold for closure. Subjected to elevated temperature, high pressure, and inner airbag and outer mold co-extrusion, the product undergoes consolidation, resulting in a unified whole. This product is particularly well-suited for composite applications demanding seamless one-piece molding.

(2) Latex 3D Airbags. The airbag comprises an inner core foam material and an outer latex layer. The prepreg is applied directly onto the airbags surface and subjected to high temperature and pressure. As the foam material contracts, the external latex endures sufficient air pressure. Co-extrusion with the outer mold solidifies and shapes the entire product. Post-molding, the contracted material is easily removed, as the latex does not adhere to the product, facilitating the extraction of the complete airbag. Alternatively, a release airbag or heat-shrinkable fluorine film can replace the external latex, supporting composite part molding under high temperature and pressure. This product is ideal for one-piece molding of composite products.
