Plastic Film Blowing Machine

Steps to start the film blowing machine normally:

1.Heating the Blown Film Extrusion Machine body, head, die head, and control the temperature of each point within the index.

2. If you drive after a long stop, the heating temperature of each point needs to be kept constant for 10-30 minutes after reaching the target range.

3. Start the air compressor and stop when the cylinder pressure is 6-8kg/cm.

4. According to the film folding diameter, thickness requirements and extruder production capacity for processing, estimate the pulling speed and stable bubble diameter.

5. After the temperature of each point meets the requirements, put on labor protection supplies and start the tractor, blower, and extruder in order.

6. When the die outlet is uniform and uniform, you can slowly pull up the tube blank while wearing gloves, and at the same time, close the end of the tube blank and slightly open the air inlet regulating valve to blow in a small amount of compressed air from the center hole of the mandrel. Carefully guide the foam stabilizer, herringbone plate, and penetrate the traction roller and guide roller until it is taken up.

7. Check the thickness and width of the film everywhere, and adjust them to meet the requirements.
