The difference between PVC cold extrusion and thermolplastic extrusion
PVC cold- extrusion processing is a commonly used PVC extrusion production method for the production of PVC high-calcium pipes and PVC high-calcium hard profiles. PVC high-calcium pipe cold-top extrusion is also called internal pressure extrusion, directly on the machine Cooling and shaping inside the head, no shaping mold is needed, and the production speed is slow.
The production process is to directly enter the water tank for immersion or spray water cooling after being discharged from the die of the machine head, so that the PVC material is quickly cooled from the die outlet to achieve the effect of cooling and shaping. The appearance of the product processed by the pvc cold extrusion method is more Bright, good gloss.
Our company specializes in producing pvc cold extrusion processing equipment and molds.
PVC hot drawing extrusion is that the PVC material comes out of the die and is cooled and shaped by the shaping die or the soft PVC is directly fed into water for cooling and shaping.
