RECENT TRENDS IN HOT ISOSTATIC PRESSING.

HIP WAS INVENTED IN THE MID 50'S IN USA, AND EXTENSIVELY DEVELOPED BY THE AEROSPACE INDUSTRY IN THE 70'S IN BOTH USA AND EUROPE. THE RECENT RAPID INCREASE OF PATENT APPLICATIONS AND EQUIPMENT INSTALLATIONS IN VARIOUS INDUSTRIES SIGNIFY A REMARKABLE DEVELOPMENT IN JAPAN. ACTIVE RESEARCH AND DEVELOPMENT FOR EXTENSIVE INDUSTRIALIZATION OF HIP TECHNOLOGY ARE SPREADING FROM CEMENTED CARBIDE TO ELECTRONIC MATERIAL AND HEAT RESISTING CERAMICS. NEW APPLICATIONS HAVE DIVERSIFIED INTO: - (1) 2000 D. C CLASS TEMPERATURE OPERATION FOR HIGH PERFORMANCE CERAMICS, (2) PREHEATING AND MODULAR SYSTEM FOR HIGH PRODUCTIVITY, (3) STANDARD COMPACT HIP FOR RESEARCH AND DEVELOPMENT USE.
