Abstract

The polyimide hot isostatic pressing molding workpiece process method provided by the invention comprises the following steps: step S1, preparing polyimide; s2, the core mold is placed in a sheath; s3, filling polyimide between the core mold and the sheath; s4, the sheath is vacuumized; s5, carrying out hot isostatic pressing treatment on the sheath; s6, the sheath is cooled, and the polyimide product is taken out. The polyimide hot isostatic pressing forming workpiece technological method is simple in process, large-size, different-height-diameter-ratio and high-density polyimide workpieces can be obtained, the production efficiency can be improved, the production cost can be reduced, and the production cost can be reduced. The polyimide hot isostatic pressing forming part process method is simple in process, large-size, different-height-diameter-ratio and high-density polyimide parts can be obtained, the production efficiency can be improved, and the production cost can be reduced.
