'pragma' => 'no-cache', Hot isostatic pressing can be used to manufacture metal components directly, or to densify parts from other powder metallurgy processes. It also describes several pressure densification methods, including hot isostatic pressing, gas pressure sintering, molten particle deposition, and sol-gel processing. Hot isostatic pressing is thus also used as part of a sintering (powder metallurgy) process and for fabrication of metal matrix composites,[3] The hot pressing method is a simultaneous process of press molding and heat sintering, and the advantages of this process are: (1) During the process of hot pressing, since the powder is in a thermoplastic state, the deformation resistance is small, and plastic flow and densification are easy, so the required molding pressure is small. Instead, a large number of squeezed particle boundaries appear, and the densification speed slows down. Address: NO.1299, XinJinQiao Road, Pudong New Area, Shanghai, China.
