1 The machine is equipped with inner tube and tire tread extrusion heads, and can also be equipped with other extrusion heads as required by users.
2 A machine body temperature measuring and indicating device is installed. The feeding zone over 150 is equipped with side rolls for the enhancement of feeding capability.
3 The screws and bushes are subjected to nitrogenation treatment to get enough strength and wear-resistance.
4 The reducer has a forced lubrication unti, which is featured by high transmission efficiency, long service life and low noise.
5 The machine over 150 is driven by a variable-speed motor.
6 The side rolls are designed as side-open type for easy rubber removal
