High-temperature plate lining teflon process

The invention relates to the technical field of plate lining processing, and discloses a high-temperature plate lining polytetrafluoroethylene process, which comprises a molding press, a plate lining mold, a sintering furnace and a cooling machine, resin is poured into the plate lining mold, an upper mold plate of the mold is driven by the molding press to press a lower mold plate of the mold to extrude the resin, the resin is preformed, and the preformed plate lining is demolded and then trimmed. And the trimmed plate lining is fed into a sintering furnace to be heated and then cooled, the lining plate is taken out until the temperature reaches the room temperature, and then the lining plate is fed into a cooling machine to be rapidly cooled. The method has the beneficial effects that the extrusion surfaces of the upper die plate and the lower die plate of the die are pretreated, impurities are blown off, rust and attachments on the extrusion surfaces of the upper die plate and the lower die plate of the die
