An open-face molding apparatus for use in open-face injection molding operations to more accurately control the thickness of coatings applied to workpiece surfaces of slightly varying contour profiles. A conformable tool face is carried by a rigid tool backing and a perimeter seal releasably seals the conformable tool face around its perimeter to the workpiece surface. The conformable tool face and perimeter seal define a mold cavity together with the workpiece surface. An array of actuators are connected between the rigid tool backing and the conformable tool face to provide a desired tool face contour and desired spacings between the conformable tool face and a workpiece surface by deflecting the conformable tool face relative to the rigid tool backing.
