Product Description
Inflatable rubber core mold used for construction projects which is produced by adopting high strength rubber air-bag technology can replace wooden core mold when pouring air-core reinforced concrete prefabricated parts. This kind of core mold is easy to install and disassemble, and it can be cleaned repeatedly, greatly saving the work time and materials used in wooden core mold, which is suitable for large reinforced concrete hollow slab inner mold, so it can be used in the project of building bridge, culvert and concrete hollow slab.
