An assembly tray is injection molded with an open bottom to provide access to articles supported by the tray during manufacturing. Gear teeth are included on the bottom of the tray in the shape of a timing belt for indexing the tray during manufacturing. Stacking ledges are provided in the rim on top of the tray so that one tray can be stacked on top of another without sticking. A torsion box is provided on the sides of the tray to provide torsional stability. The assembly tray can be selected from a stack of other trays, used in automated manufacturing and stacked in another stack. The assembly tray is particularly suited for assemblying components of tape cassettes.

An injection-molded plastic assembly tray for supporting a plurality of articles during manufacturing of the articles, the assembly tray comprising: a single frame of shallow height and elongated length compared to width, for directly supporting therein the plurality of articles arranged along the elongated length, the frame including ends, each of said ends having a top edge and a bottom edge, the width being measured parallel to the bottom edge of said ends; sides, connected to said ends, each of said sides having a top edge and bottom edge, the elongated length being measured parallel to the bottom edge of said sides; and torsion boxes, extending along substantially all of the elongated length of each of said sides at the top edge thereof, for providing rigidity of said single frame, each torsion box having a solid top, solid sides, solid ends, an open bottom and stacking spacers abutting and supporting the sides and top of each torsion box, the stacking spacers extending through the open bottom of the torsion box so that when a first assembly tray is stacked above an empty second assembly tray, the stacking spacers of the first assembly tray contact the top of the torsion box of the second assembly tray; and a bottom, connected to the bottom edge of each of said sides and said ends, having a continuously open area along the elongated length through which each of the plurality of articles can be directly accessed during manufacturing.
