摘要： A method of vaporizing and removing a binder from a powder-molded product containing the binder, which method comprises:coating the greater part of the surface of said powder-molded product with a thin resin film having air-tightness thereby leasing an exposed surface portion;pressurizing the thus-coated surface portion of the pressure-molded product hydrostatically;vaporizing the binder in the power-molded product under said hydrostatic pressurization; andremoving the vaporized binder to the exterior of the power-molded product through said exposed surface portion not coated with the thin film.
