PRODUCTION OF WOODEN VESSEL USING NEW DIE

摘要

PROBLEM TO BE SOLVED: To produce a traylike wooden vessel formed of ligneous material by hot-pressing formation in extremely high quality rate without causing a crack. SOLUTION: Hot-pressing formation is performed by using the die in which difference is provided in clearance between a female die and a male die of the die in accordance with a part to be formed of a traylike vessel and clearance of a part 2 corresponding to the peripheral edge region of the bottom of the traylike vessel is largest and clearance of a part 1 corresponding to the central region of the bottom of the traylike vessel is smallest and the part corresponding to the central region of the bottom of the traylike vessel shows a bottom-raising shape and furthermore the surface coming into contact with ligneous material is applied to Teflon-processing.
