热成型是一项用以发挥粉末冶金材料性能潜力的最新生产工艺。热成型粉末冶金件的密度可达铁密度(7.78克/厘米~3)的99～100％。 所谓热成型实际上是将已在保护气氛中感应加热至815～1095℃的烧结预制件放置到巴加热至205～425℃的封闭模中重新压制,从而提高制件的密度,改善制件的机械性 Thermoforming is the latest production process to exploit the performance potential of powder metallurgy materials. Thermoformed powder metallurgy pieces of density up to iron density (7.78 g / cm ~ 3) of 99 to 100%. The so-called thermoforming is actually placed in the protective atmosphere of induction heating to 815 ~ 1095 ℃ sintering preform is placed in the bar heated to 205 ~ 425 ℃ closed mold re-pressing, thereby increasing the density of the workpiece to improve the workpiece Mechanical
