Introduction of the heating method and power of the screw barrel of the granulator
Introduction of the heating method and power of the screw barrel of the granulatorIn the plasticizing process of the injection molding machine, a large part of the screw barrel of the granulator mainly depends on the heating of the barrel.
Pelletizer screw barrel heating method:
Jane heating widely adopts the method of resistance heating, and uses thermocouples to achieve segmented temperature control and inspection side. Resistance heating is the use of resistance to generate heat to heat the barrel, and then transfer the heat to the plastic in the barrel. Resistance heating mainly includes band heaters, cast aluminum heaters, ceramic heaters, etc. These heaters have the advantages of small size, easy manufacturing and maintenance.
Granulator barrel heating power:
When determining the heating power of the barrel, in addition to considering the heat required for plasticization, it also needs to meet the productivity requirements of the injection molding machine to ensure that the barrel has a sufficiently fast heating rate. The heating time of the machine heating does not exceed 30min for small machines, and generally about 1h for large and medium-sized machines.
