Control system

Adopt programmable PLC control system control, combined with man-machine interface (touch screen), to achieve stable action and easy circuit maintenance.

Exit System

Adopt fast and slow speed and segmented injection design, change the required data according to different product requirements, and cooperate with the analog data of the potentiometer to achieve accurate and stable feeding and injection positions.


It is used to control the temperature of the feeding system and the storage system to ensure that the temperature is controlled within the temperature range you set.

Storage System

Using automatic constant temperature design, setting the required temperature according to different rubber formulations can save vulcanization time, improve work efficiency, save electricity and labor, reduce production costs, and increase profits.

Formwork agency

The mechanism can be customized according to the needs of customers, and plays the role of mold splitting and ejection.

Clamping potentiometer

The potentiometer is used to control the switch function, so that it can achieve real digital movement control, and the fast and slow position is more accurate.

Pressure Control System

The system uses a pressure sensor to control the clamping pressure, which truly achieves digital control. You only need to input the clamping pressure and speed you need on the touch screen, and the computer will automatically complete your instructions and display it on the touch screen. If it is lower than the set value When the system will automatically make up the pressure.
