Power cover plates are mainly used to produce cement power cover plates, power grid cover plates and cable ditch cover plate. The cable cover mold is mainly made of polypropylene plastic and injection molded by injection molding machine. The produced power cover die has strong toughness, no deformation, high brightness, high density and low breakage rate. The manufacturing process of power supply cover plate adopts concrete vibration prefabricated tools. After the cement concrete is poured into the plastic mold of the cover plate, it is molded by a vibrating platform and naturally cured until the cement solidifies, so that the demoulding can be completed, thus completing the whole production process. General situation of power cover mold: railways, urban roads, township cement roads, villa roads, development zones, factory roads, water conservancy projects, etc. have blossomed everywhere, and supporting prefabricated components such as manholes, rainwater wells, kerbs, kerbs, flat stones, shoulder stones and slope protection have gained unprecedented development opportunities.
