Inflatable Mandrel, Bridge Rubber Pneumatic Mold

Inflatable Mandrel, Bridge Rubber Pneumatic Mold

Bridge inflatable rubber core mold is inflatable in soft rubber, use compressibility of air to its elasticity, use rubber to its limpness and gas tightness, and use anti-tensile cloth to its toughness. It is made for different shape under particular pressure, and at the same time it could sustain some concrete pressure, at last, achieve its function of making holes. It is based on the technique of preliminary-making concrete hollow slab inner mold, so it can be used in the project of building bridge, culvert and concrete hollow slab.
The construction technology is simple and convenient, safe, and health. It would not pollute the environment.
