Detailed operating procedures of the cast film machine:
1. Prepare related tools, such as copper sheet, alcohol, mold release agent, etc.

2. Check whether the die head, rollers, etc. of the casting machine and their surroundings are clean, then clean the die head with alcohol, paraffin wax and gauze, or clean it with a copper sheet and spray it with release agent.

3. Check whether the rotation and pressure of each roller of the cast film machines are normal, and whether the heat exchange system, pump and pressure gauges can work normally.

4. Wear each roller with a thick film through film, and then put the chilled roller in a closed state to press the film.

5. Start the cast film machine, check whether the thick sheet and the melt have been adhered firmly and smoothly, and then pull the thick sheet tightly toward the person standing at the exit.

6. Adjust the appropriate working position and carefully complete all operations.

7. After the production is over, manually adjust the cast film machine to the non-working position, and then introduce the material into the receiving tray, and stop the machine.
