I The cause


1. Improper adjustment of the throttle valve for slow mold closing


2. The position of the slow-speed mold closing actuator is improper, the actuator does not touch the proximity switch, or the proximity switch at the slow mold closing speed and the end point of mold closing is broken.


3. The clamping pressure is too high


4. The actuator does not touch the proximity switch after the mold is closed
