PVC pipe, PE pipe production process of surface pitting may be due to impurities in the molten material, the caliber of water flow is not appropriate or the water contains impurities and other reasons.
Screws have to be scrapped is generally due to that the clearance between screw and barrel is so large after a long-term abrasion that the material can’t be normally extruded， and also there’re examples that the machine's working ability goes beyond the limit because of improper design or operation. The following is a brief description of the causes of screw abrasion.
Let’s quickly look at some components of the machine. A plastic extruder consists of four major zones. Though plastic extruder comes in different designs and manufacturers, the primary zones are the same.
Besides, by modifying the traction speed, the plastic pipe's wall thickness may be adjusted to match the standard. According to practice, the overall tensile strength of plastic pipes generated without traction is clearly lower than that produced with traction. However, and the yield can be enhanced when manufactured with traction devices.
To use the PCV granulating line longer, there are things you must implement. These are according to the minimum standards required by the manufacturers. Meanwhile, it is essential to source your machine from a reputable manufacturer. It will save you the stress of incessant breakdown.
