Qingdao Shuangxing Rubber Machinery Co., Ltd. developed a fully-independent semi-steel four-mode active die-casting vulcanizing machine successfully developed and successfully went offline. DoubleStar broke through more than 120 comprehensive technical problems including manipulator opening and closing, and active mode adjustment. Nearly 20 of them were world-class technical problems and finally succeeded. The on-site test proves that the double-star semi-steel four-mode active die set-type vulcanizing machine can fully meet the requirements of users, and has the advantages of high technological content, high production efficiency, space saving, etc. compared with the common double-mode vulcanizer currently produced in China. , Car Seat Cover Co., Ltd. , http://www.nscarmat.com
