Method for controlling the extruder head pressure of plastic sheet production line

Release time:2022-08-09 16:04

The use of plastic sheet production lines greatly facilitates many of our factories and the production of enterprises. The following article explains in detail how to effectively control the extruder head pressure when using this technical equipment. Let's take a look.

In order to reflect the extrusion condition of the extruder head, the pressure of the extruder head needs to be measured. Because the domestic equipment does not have the extruder head pressure sensor, and usually uses the screw after extrusion thrust measurement instead of the head pressure measurement, the screw load meter (ammeter or voltmeter) can correctly reflect the size of the extrusion pressure.

The fluctuation of extrusion pressure is also one of the important factors that cause the instability of the extrusion quality of enterprise equipment. The fluctuation of extrusion pressure is closely related to extrusion temperature, the use of the cooling devices, the length of the continuous operation time, and other factors. When the abnormal phenomenon of change occurs, Can be eliminated, quickly eliminated, must be reorganized production should be decisively shut down, not only we can effectively avoid the increase of waste, more can prevent the occurrence of safety accidents. 

When the plastic sheet production equipment was used for research, The control of the extruder head pressure we can carry out the actual operation practice of the enterprise according to the content explained in the article. In future use, this development requires very high equipment to improve the operating system only their own specific standard operation, in order to effectively avoid the occurrence of various failures, and prolong the service life of the equipment.
