A rubber dam is a bag type water retaining dam formed by inflating it with water (air) through the filling and discharging pipeline, so the inflatable core mold of the rubber dam is particularly important.

Inflatable rubber core mold is a cylindrical bag that can expand and contract, used to form a cavity of concrete components. When manufacturing hollow components, it is placed in the middle and filled with compressed air. When the concrete solidifies, the compressed air in the bag is released, and the capsule shrinks and can be extracted from the cavity. It is easy to use, economical and durable, and can be soft and shrink without inflation. It can be folded or curled at will. After inflation, it has sufficient strength to withstand the pressure of concrete, which is unparalleled by any traditional rigid template. Suitable for extracting holes from reinforced concrete components, including piles, roof trusses, roof panel columns, beams, underpasses, and other components, it is widely used in industrial and mining foundations, highway bridges, construction projects, and hydraulic engineering (docks, shipways, docks). The construction practice has proved that the capsule hole drawing process equipment is simple, which not only saves materials, but also has the characteristics of variable shapes, which can form circular, elliptical, rectangular, arch, Octagon, trapezoid and other pipes. It can also be formed into straight holes, variable cross-section holes, etc., which can make the building structure lighter, thin-walled and hollow, and change the situation where concrete has always used rigid formwork.
