1. The PE pipe production line uses specialized extrusion machines for HDPE and PP pipes, with screws equipped with barriers and mixing heads. The machine barrel adopts a new type of slotted machine barrel, which has good plasticization and mixing effects, large extrusion volume, and is very stable.
2. The PE pipe production line is designed with spiral die heads for HDPE and PP large-diameter thick walled pipes. This die head has the characteristics of low melt temperature, good mixing performance, low mold cavity pressure, and production.
3. The PE pipe production line adopts proprietary technology for sizing and cooling systems, using water film lubrication and water ring cooling to meet the requirements of HDPE and PP materials, ensuring the stability of diameter and roundness in high-speed production of thick walled pipes.
4. The PE pipe production line adopts a specially designed multi-stage vacuum sizing box to control the vacuum degree, ensuring the dimensional stability and roundness of HDPE and PP pipes. The extruder and traction machine are controlled by imported speed controllers, which have good stability, high accuracy, and high reliability.
5. The operation and time of the PE pipe production line are programmatically controlled by PLC, with a good human-machine interface. All process parameters can be set and displayed through the touch screen. A dedicated extruder for marking lines can be assembled to produce pipes with colored markings that meet national standards.

Startup inspection and maintenance of plastic film blowing machine
A plastic film blowing machine heats and melts plastic particles before blowing them into a thin film. There are many types of plastic blow molding machines, including PE, POF, and so on. Next, let me talk about the inspection and maintenance of plastic blow molding machines before starting up.
1. The temperature control of the plastic film blowing machine is intact, and the heating appliances are intact. Pay attention to adjusting the heating temperature at each point in a timely manner within the specified range.
2. Check the traction speed and control the thickness of the film.
3. Observe and adjust the uniformity of the film thickness, and ensure that the bending diameter meets the standard.
4. Check the pressure of the air storage cylinder. The plastic film blowing machine should not be too high, but there should be a backup pressure.
5. Check and control the raw material ratio and mix evenly.
6. Check for impurities in the raw materials, especially by promptly using a magnet to check for iron mixing.
7. Check the gearbox position of the plastic film blowing machine and the lubrication of the air compressor cylinder lubricating oil.
8. Regularly check the temperature rise and mechanical transmission of each operating motor.
