The invention relates to the technical field of fluoroether rubber
processing, in particular to a manufacturing method of a
perfluoroether rubber part, which specifically comprises the following steps: placing the
perfluoroether rubber part in a
vulcanization mold; heating the vulcanizing mold to 80-120 DEG C, and preserving heat for more than 10 seconds, so that the
perfluoroether raw rubber is preliminarily softened; continuously preserving heat, covering a vacuum cover outside the
vulcanization mold in a sealing manner, and repeatedly pressing the
vulcanization mold up and down while vacuumizing, so as to promote the softened perfluoroether
raw rubber to flow and exhaust, fill the mold cavity and overflow; heating and vulcanizing; a
cooling medium is input for rapid cooling; and cooling to 80-120 DEG C, opening the mold and taking the material. The problem of poor flowability of the perfluoroether rubber is improved by virtue of accurate segmented
temperature control and mechanical action: firstly, the
softening temperature of the perfluoroether rubber is set to be 80-120 DEG C, and the
rubber material is softened but not vulcanized; and secondly, the softened perfluoroether
raw rubber is jointly promoted to flow and exhaust by combining vacuumizing and up-and-down pressing actions of the vulcanization mold, and the mold cavity is filled with the softened perfluoroether raw rubber and overflows.
