Changshu smoothly extruder da plastic products factory to talk about how to correctly use

Extruder is PVC plastic pipe material for the production of PVC plastic pipe production line depends on the necessary machinery and equipment, and ensure product quality and production efficiency the important influence factors of extruder used correctly becomes an important factor in the production of PVC plastic pipe material. Changshu well below da plastic products factory talk about how to correct use of extruder.



extruder equipped with quantitative loading equipment, make out in and add the shoes to match, to ensure that products stable extrusion. Due to the characteristics of the conical screw, charging period has larger diameter, the heat transfer area of raw material and the shear velocity is large, is advantageous to the raw material of plasticizing, metering section of the screw diameter is small, reduces the heat transfer area and the shear rate of melt, can make the melt extrusion under low temperature. Screw within the barrel rotates, the plasticization of PVC plastic pipe fitting mixture into the nose, so as to achieve compaction, melting and mixing homogenization; And achieve the purpose of the exhaust, dehydration. Feeding device and the screw driving device adopts frequency control of motor speed, which can realize synchronous speed.



extrusion die head part is PVC plastic pipe forming close to build parts, it will be after compaction, melting and mixing homogenization of PVC, the following materials by the screw to the die head, to finalize the design and quality control of products.
