First we need know how does the plastic film producing.
1.Heat the plactic resin granula.
2.Extruder the film by screw.
3.Cooling and rewinding.
Second we need know there are various type accoding to diffirent material, just like PE, POF, PP, PVC and so on. If you use the new resin material, the blowing film will be very clean and smooth and strong.
Then we discuss how to heat film blowing machine before production.
1.Pull down the original heating ring of the modified part.
2.Measure the size of the barrel. Include the primeter. The calculate the heat insulation cotton quantity. And confirm if the winding space is enough according to the heating ring power.
3.Packaging the heat insulation cotton on the barrel by high temperature bandage, keep the heat insulation cotton thickness between 1.5-2.0CM.
4.Package one layer 0.5mm insulating resin plate on the heat insulation cotton to make the it beautiful.
5.Winding the electromagnetic wire on the barrel strainly.
6.Install the electromegnetic heating control cabinet.
