 Plastic pipe extrusion, plastic hose extrusion temperature is generally higher than the hard plastic pipe extrusion temperature is lower. If the die temperature is too high, then the injection molding machine plastic pipe appears scorch phenomenon; if the injection molding machine die temperature is too low, then the plastic tube surface brightness difference phenomenon.

If the extruder screw speed is too slow, then the plastic tube surface prone to moire; if pulsation extrusion, injection molding machine plastic pipe so prone to the phenomenon of bamboo-like; if the injection molding machine screw speed is too fast, then the surface of the plastic pipe mouth friction between the mold overheating can cause the product surface scorch phenomenon. Therefore, the screw speed can be selected within 20-40r / min range.


Similarly, if you pull too fast or too slow will make the horizontal and vertical injection molding machine plastic pipe contraction increased, the surface will be prone to wrinkles. Thus, pulling speed according to the different diameter plastic pipe, make appropriate adjustments. For example, the diameter of 9-16MM plastic tube traction line speed can be selected within 8-12m / min range; 19-25mm diameter plastic tube traction line speed can be selected within 4-8m / min range.

Plastic pipe extrusion, we want to pay particular attention to the injection molding machine die temperature, extruder screw speed and traction speed and other factors, so as to prevent the injection molding machine plastic pipe extrusion scorch the surface, the appearance of wrinkles.
