Abstract

A mold assembly for forming a film includes a transparent bottom mold, a top mold, a case, and a lighting member. The transparent bottom mold defines a cavity for receiving a workpiece and a plurality of liquid compositions. The top mold is matched with the bottom mold to accommodate the workpiece between the bottom mold and the top mold. The case receives the bottom mold and the top mold placed therein. Air in the case is exhausted from the case to coat the plurality of liquid composition on the workpiece. The lighting member emits light on the liquid compositions to solidify the liquid compositions to form a film on the workpiece.
