Manufacturer makes concrete decision to replace external vibrators
Replacing external electric vibrators resolves one concrete manufacturer's cost and fracturing concerns.
Cretex Companies, Elk River, Minn., manufactures products ranging from heart pacemaker components to prestressed concrete bridge beams. The manufacturer's concrete products include pipe, precast reinforced box culverts, retaining wall systems, beam shapes, and many more that are used in a wide range of road, bridge, and construction projects. During the manufacturing process, high-frequency external vibration is used when concrete is poured into steel molds. Vibration pushes trapped air within the concrete mixture to the surface before the concrete sets, forming stronger concrete. In 2009, the manufacturer began looking for a way to eliminate the multiple issues it was experiencing while producing its large-scale concrete products.
