Abstract
A plastic floor tile is formed by molding a body of a first polymer compound and overmolding features onto the body from a second polymer compound. The compounds may be different from each other in hardness and/or color. The overmolded features may include raised pads on the upper surface of the tile. The pads on the upper surface may be injection-molded from the lower surface through through-holes, which are smaller in area than the area of the pads.
