Issues and Solutions in the Production of PVC Pipe 16-32mm Four-out Production Line

PVC tube is mainly used for water supply and drainage, and 16-32mm PVC small tubes are also commonly used as electric power threading pipes, widely used in the power industry.   

Jwell machinery company focuses on variousPVC, HDPE, PP, PPR pipe extrusion equipment (Plastic Pipe Extrusion Line Extruder Machine Manufacturer Factory China | Jwell Machinery (jwellextruderglobal.com)) manufacturing technology for more than 30 years, and exports high-quality plastic pipe production equipment to countries around the world every year.

Our independently developed and manufactured PVC  pipe 16-32mm four-out production line (PVC Double-cavity/Four-cavity Pipe Extrusion Line Extruder Machine Manufacturer | Jwell Machinery (jwellextruderglobal.com) features high output, with the highest linear speed of a single pipe up to 25m/min, fast speed, energy-saving and efficient. The production speed of the four pipes can be independently controlled. The entire pvc pipe extrusion machine line is equipped with automated coiling and packing machines, with high production efficiency, which greatly saves labor costs.

Our PVC pipe production line adopts a specially designed screw and die structure to ensure that the plastic raw materials reach a stable melting state and plasticization, improve the quality and production stability of the pipes.

In response to common problems encountered by customers during the PVC four-out pipe production process, jwell extruder have adopted quality plastic extrusion equipment and summarized the following solutions:

1. After the PVC raw material comes out of the mold, the color becomes yellow and soft. Possible reason: the screw mechanism does not match the raw material, which causes the PVC raw material to be over-melted. Solution: adjust the screw structure; or adjust the raw material ratio; or add some stabilizers. Try these methods repeatedly until the PVC pipe meets the requirements.

2. The production speeds of the four PVC pipes are very uneven. Possible reason: the screws on the PVC pipe mold are not tightened uniformly or the internal structure of the mold is unreasonable. Solution: adjust the screws on the PVC pipe mold or adjust the PVC pipe die core rod.

3. After the PVC pipe is produced, the cross-section of the pipe material is powdery. Possible reason: the vacuum on the shaping table is not sufficient, affecting the quality of the pipes. Solution: check whether the vacuum pump on the shaping table works properly and can provide sufficient vacuum.

4. After producing for some time, one of the PVC pipes is found to be bent. Possible reason: the raw material ratio is not suitable, or there is a problem with the vacuum on the shaping table. Solution: adjust the PVC pipe raw material ratio; check whether the vacuum pump on the pipe shaping table is running normally, and whether there is air leakage at the position where the pipe enters the vacuum box.
