Abstract

PURPOSE:To mold a sintered product with good quality in a short operation time by acting predetermined pressure and temp. on an object to be molded through a metal film and a powder having flowing property. CONSTITUTION:At first, to the end part of a sample (an object to be molded) 1, a conveying handle part 2 in constituting a film is attached by welding or the like and, to said sample 1, a film 3 comprising a ceramic powder which is not softened at a treating temp. and shows flowing property against external force as a particle aggregate is formed by an appropriate method. Next, in an evacuated atmosphere, the entire surface of the film 3 is covered and a metal film 4 is formed so as not to permeate a gas through the film 3. By this method, a sample 5 to be molded constituted in such a state that the inside of the film 4 is degassed and hermetically sealed is obtained. The obtained sample 5 is placed under a high temp. and high pressure environment and predetermined pressure and temp. are acted on the sample 1 through the film 4 softened at a high temp. and the film 3 having flowing property. After this operation, the films 3, 4 are removed to take out the sample 1 and the knob part 2 is removed.
