Description

Technical Field

[0001] The utility model belongs to the technical field of isostatic pressing equipment, and in particular relates to a novel polytetrafluoroethylene molding isostatic pressing equipment. Background Art

[0002] Isostatic pressing equipment is a molding equipment that works under ultra-high pressure. Isostatic pressing is a process in which the object to be processed is placed in a specific mold, and then the mold with the workpiece is placed in a closed container filled with liquid, and the pressure is gradually increased through the booster system. Through the liquid pressure transmission, each surface of the object is subjected to equal pressure, and the molding process is carried out under the restriction of the mold. During the compression process, the distance between the molecules of the actual workpiece is reduced, and the density is increased, which changes the physical and even chemical properties of the pressed object.
