What Preparations Does PVC Ceiling Panel Extruder Machine Need To Do?

Pulished on Nov. 23, 2018

First, press the “Prepare to drive” button on the PVC Ceiling Panel Extruder Machine, then the “Drive” button, then slowly rotate the screw speed adjustment knob, and the screw speed starts slowly. Then gradually increase, while feeding a small amount. Pay close attention to the change of the indicator of the main current meter and various indicator heads when feeding. The screw torque cannot exceed the red mark (typically 65%-75% of the torque table). Before the plastic profile is extruded, no one should stand in front of the die to prevent injury due to bolt breakage or wet foaming of raw materials.

After the plastic is extruded from the die, the extrudate is slowly cooled and introduced into the traction device and the sizing die, and the devices are activated. The extruder from PVC Skirting Board Extrusion Machine Supplier is then based on the indicated values of the control instrument and the requirements for the extruded product. The parts are adjusted accordingly to bring the entire extrusion operation to a normal state. And according to the need to add sufficient material, the plastic extruder uses a metering feeder to feed evenly and at equal speed.

When the die is discharged uniformly and the plastic is good, the manding sleeve can be pulled. The degree of plasticization needs to be judged by experience. Generally, it can be judged according to the appearance of the extruded material, that is, the surface is shiny, free of impurities, no foaming, coke and discoloration, and the extrusion material of the plastic extruder is squeezed by hand to There is no burr or crack in a certain degree, and there is certain elasticity. At this time, the material is plasticized well. If the plasticization is poor, the screw speed, barrel and head temperature can be adjusted appropriately until the requirements are met.
