In the rubber industry, column-type flat vulcanizing machine is with the older model, our past use of flat belt vulcanizing press for column type, but the use of box-type structure. Box type flat with flat sulfide machine and column type flat with flat sulfide machine compared, has following advantages: in must of Center from Xia, allows installation larger diameter of hydraulic cylinder, to can reduced hydraulic cylinder number, and structure simple, maintenance volume less; Shang beam by force reasonable, by needed of section die volume far than live type of small, can reduce weight; manufacturing installation simple, pipeline configuration hidden, machine shape neatly beautiful. Frame type flat vulcanizing machine lateral stiffness of a single box plate worse than post, but due to the frame type flat vulcanizing machine frame are combined into multiple boxes on the Board, so the machine has enough lateral stiffness.
