摘要： A system and a method for molding a part from fiber cement, or fibrocement, slurry are provided. The molding is preferably made by pressure injection of the slurry. The slurry comprises cementitious material, additives, fibers and water. The fibers can include polypropylene, polyethylene, polyacrylic, cellulose, and/or asbestos fibers. First and second molding sections define, at least partially, a chamber. The second molding section comprises at least one evacuating channel. The system includes a slurry inlet communicating with the chamber, for inserting the slurry. A bladder covers the first molding section, the bladder being inflatable for compressing the slurry between the bladder and the second molding section. A filter covers the second molding section and allows water contained in the slurry to pass through while retaining the cementitious material and fibers within the chamber. A pressurized fluid inlet port communicates with at least one conduit for inflating the bladder.
