Abstract: A process for fabricating a molded carpet laminate includes supporting a carpet layer in a molding tool that has mold dies that define a mold cavity. The mold dies are then moved from an open position to a partially closed position. In the partially closed position, a heated polymer material is injected into the mold cavity. The heated polymer material incompletely fills the mold cavity on the working side of the carpet layer. The mold dies are then moved from the partially closed position to a closed position to spread the heated polymer material and fill the mold cavity on the working side of the carpet layer to form a molded polymer wall. The molded polymer wall adheres to the working side of the carpet layer to form a molded carpet laminate. The mold dies are then moved from the closed position and the molded carpet laminate is cooled.
