1. The extruder body, machine head and die head are heated, and the temperature of each point is controlled within the index range.
2. If the vehicle starts after a long stop, the heating temperature at each point should be kept constant for 10-30 minutes after reaching the target range. If the car starts within half an hour of stopping, no constant temperature is needed.
3. Start the air compressor and stop when the cylinder pressure is 6-8kgcm.
4. According to the diameter and thickness requirements of the film and the consumption of the extruder, the processing can be stopped and the traction speed and foam diameter can be estimated.
5. After the temperature of each point reaches the requirements, wear labor protection products, and start the tractor, blower and extruder according to the next time.
6. When the average difference at the outlet of the mold is reached, put on gloves and slowly pull the tube blank, block the end of the tube blank, gently open the intake regulating valve, blow a small amount of compressed air into the center hole of the mandrel, carefully guide the foam cage and herringbone plate, and insert the pull roller and guide roller into the coiling.
7. Check the thickness and width of each film and adjust to meet the requirements.
