The preparation method of the low price fluorine rubber ring is made by using a mold. The mold is a pair of flat flat molds, and a longitudinally corresponding circular groove is arranged on the upper and lower flat planes of the mold to form the upper and lower flat planes. There is a straight round hole at the seam, and the mold is connected to the heating device. The preparation method is to first plasticize the fluororubber, mix and process it, use an extruder to extrude a round strip of raw rubber, and put the rubber strip into the cavity at the lower part of the mold. In the tank, the head of the first section is left outside the mold when feeding, close the upper mold and pressurize, heat the mold to 155 ℃ ~ 165 ℃, open the mold after pressing, and sequentially feed and process, the last remaining section is not made. process, then remove the rubber strip and cut it off, lap the part of the tail and the unprocessed head together in a ring shape, and perform vulcanization again. The product made by this method has high precision, reduced production cost, simple operation, and finished product. High rate.

The above is a brief introduction to the relevant knowledge about the preparation method of Low price fluorine rubber ring.
