Reasons for the unstable current of the main machine of plastic extruder: (1) Uneven feeding. (2) The main motor bearing is damaged or poorly lubricated. (3) A section of heater fails and does not heat. (4) The screw adjusting pad is wrong, or the phase is wrong, and the components interfere.
Read MoreWhat is the function of the barrel in the extrusion system? The barrel includes a screw, which rotates in the barrel. When the screw rotates and the thread is pushed, the heat is transmitted to the material by heating outside the barrel. In addition, the volume of the thread is gradually reduced,......
Read MoreIn most extruders, the change of screw speed is realized by adjusting the motor speed. The driving motor usually rotates at full speed of about 1750 rpm, which is too fast for an extruder screw. If it rotates at such a fast speed, too much friction heat will be generated, and the uniform and well st......
Read MoreFirstly, the twin-screw extruder has the extruder principle of single screw extruder: solid conveying, melt pressurization and pumping, mixed stripping and devolatilization, but it is not simply so. The research of twin-screw extrusion theory began late, coupled with its many types, complex screw ge......
