The problem of wet-cast concrete products getting stuck or being uncontrollably ejected from a flexible mold during demolding is solved by moving the flexible mold through a passage, defined by both a mold-receiving surface and a rotatable mold-support distanced therefrom, while moving an edge of the flexible mold along an unsmooth path that includes at least one sharp point.

An automated system and associated method of producing manhole products includes an area closed production loop where molds are moved to discrete workstations. A standard set of tasks (e.g., mold cleaning and release agent application, reinforcement placement, pre-pouring activities and inspection, filling, curing, and product demolding) are performed at various ones of the workstations. Once one of these tasks is completed, the mold moves to the next workstation. This enables a transition from ‘cast on the floor’ method to an assembly line principle.

A screeding machine includes a base unit positionable at framework that defines a concrete structure and a screed head assembly movably mounted at the base via an extendable and retractable mechanism. The screed head assembly includes a grade establishing member, a vibrating member, and elevation actuators for adjusting elevation of the screed head assembly. The screed head assembly is positioned at a screeding location via extension of the extendable and retractable mechanism and is movable over the uncured concrete in a screeding direction via retraction of the extendable and retractable mechanism. Adjustable wings disposed at and in front of the grade establishing member in the screeding direction are movable along the grade establishing member. When one of the ends of the screed head assembly is positioned at a frame portion, the wing at that end of the screed head assembly is moved to position the wing at the frame portion.

A system and method for manufacturing a set of cast stones includes a set of spray stations, a set of fill stations, a set of vibration tables, a drying rack, and a demolder connected to the drying rack. A controller is connected to each of the set of spray stations, the set of fill stations, the set of vibration tables, the drying rack, and the demolder, each of which has a set of sensors connected to the controller. The set of spray stations include a set of release stations and a set of color stations. A mold is sprayed with a release product, a set of colors, and then filled with a cementitious material. Once vibrated, the cementitious material is dried to form the set of cast stones, which is then automatically released from the mold utilizing the demolder.
