Abstract
A method of vaporizing and removing a binder from a powder-molded product containing the binder, which method comprises: PA1 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; PA1 pressurizing the thus-coated surface portion of the pressure-molded product hydrostatically; PA1 vaporizing the binder in the power-molded product under said hydrostatic pressurization; and PA1 removing the vaporized binder to the exterior of the power-molded product through said exposed surface portion not coated with the thin film.
