1. A method for manufacture of a resin tray comprising:
installing surrounding wall block molds having a shaping surface comprised of a bottom surface and a side surface forming an L-shaped cross section on a base mold with at least one screw, wherein the surrounding wall block molds have a top portion extending up forming a pinch-off surface along their circumference; installing at least one projection part having a recess on the base mold within the surrounding wall block molds to form a mold cavity comprised of the surrounding wall block molds, the base mold, and the at least one projection part; arranging a molten thermoplastic resin sheet opposite the mold cavity; pushing said molten thermoplastic resin sheet against the mold cavity; cooling said molten thermoplastic resin sheet to form a tray having a recess on its surface configured to hold a part. |
