Method of manufacturing a front cabinet for use with a display

A method for making a cabinet for containing a display screen, said cabinet comprising a front frame portion of synthetic resin having an inner edge portion for framing a display screen, a cabinet portion a synthetic resin extending rearward of the front frame portion and integral with the front frame portion, means disposed on interior surfaces of at least one of the front frame portion and said cabinet portion for supporting the display screen, wherein said front frame portion and said cabinet portions are formed of a single layer of synthetic resin except at the interior surfaces on which the means for supporting are disposed which are formed of a sandwich structure of two layers of synthetic resin surrounding a single layer of a mixture of synthetic resin and reinforcing fibers, said method comprising the steps of:

• providing a mold for injection molding the cabinet, wherein the mold defines a cavity having a shallow portion for injection molding said front frame portion and said cabinet portion as a single layer of said synthetic resin except for deeper portions for injection molding at each of said interior surfaces on which the means for supporting are disposed;
• providing a source of molten synthetic resin;
• providing a source of mixture of molten synthetic resin and reinforcing fibers;
• providing means for alternatively introducing the molten synthetic resin and the mixture into the mold by means of gates disposed adjacent the deeper portions;
• introducing said molten synthetic resin into the mold through the gates to form the single layer portions;
• and
• before said synthetic resin hardens in the deeper portions, introducing said mixture into the mold through the gates so that a sandwich structure of two layers of said synthetic resin surrounding a single layer of said mixture is produced in each of the deeper portions of the mold.
