Function Of PVC Corner Bead Extruder

Oct. 12, 2018

Part of the PVC Corner Bead Extruder is equipped with a dosing device to match the amount of extrusion with the amount of feed to ensure stable extrusion of the product. Due to the characteristics of the conical screw, the feeding section has a larger diameter. The heat transfer area and the shearing speed of the material are relatively large. The plasticizing metering section of the material has a small screw diameter, which reduces the heat transfer area and the shear rate of the melt. The melt can be extruded at a lower temperature. When the screw rotates of PVC Crusher in the barrel, the PVC mixture is plasticized and pushed to the machine head to achieve compaction, melting, mixing and homogenization, and achieve the purpose of exhausting and dehydrating. The feeding device and the screw driving device adopt synchronous frequency regulation to realize synchronous speed regulation.
