Turn on the power supply and air supply switch of the casting film machine, unscrew the emergency stop button; start the heating and cooling system of the casting film machine mainframe, and start the extrusion after the temperature of the standby cylinder reaches the set value and stabilizes for a period of time (about 20 to 30 minutes). Before starting the cast film machine for the first time, it must be determined whether the motor rotates correctly. The method of determining the rotation direction of the motor is: open the hopper, drive the motor of the jog extruder, observe the rotation direction of the screw from the feed port, and look from the tail of the screw to the head of the screw. The correct rotation direction of the screw should be counterclockwise. Otherwise, any two-phase wires of the power connector need to be replaced;

After confirming that the cast film machine is turned correctly, run it at a low speed for a short time to determine whether all parts have been installed correctly; if abnormal phenomena are found during operation, such as abnormal sound, it must be stopped immediately to check until the cause is found and excluded. Restart the cast film machine and pour the test material into the hopper.

It is recommended to set a lower speed at the beginning, such as 10 ~ 15 rpm, until the melt is extruded, the speed of the screw can be increased.
