METHOD OF MANUFACTURING STARCH-BASED BIODEGRADABLE MOLDED OBJECTS

摘要

Using a metal mold (8) having an insulating section provided with vapor release sections, pressure outside the metal mold (8) is reduced, and heating is performed while releasing vapor produced thereby through the vapor release sections. This can prevent insulation breakdown caused by condensation of large amounts of vapor produced by materials during molding and heating of starch-based biodegradable molded objects by means of resistance heating, dielectric heating, etc.
