Abstract: This paper studies the physical prototype performance of electrical screw tire vulcanizing machine and the radial tire produced by industrial prototype, which proves the working principle of electrical screw tire vulcanizing machine is feasible and can be applied to manufacture. At the same time, it has the advantages such as simple structure, convenient manufacture, reliable work, convenient operation and high precision in producing radial tires. Therefore, this technology has a broad application future, and should be popularized during improvement.

Abstract: Through the experimental comparison of free feeding technology, roller feeding technology and spiral engagement feeding technology, it can be seen that the spiral engagement feeding technology has significantly increased production capacity, improved extrusion stability, reduced the energy consumption and does not hold shaft, not leak rubber, etc; at the same time, industrial application research on spiral engagement cold feeding extruder was carried out, as well as expanding its application research on this extruder with short fiber compound and environmental protection plate compound which is composed by waste plastic, rubber compound and waste oil. It proves that the work principle of spiral engagement cold feeding technology is feasible, also demonstrates that this extruder has a broad prospect of application.
