What Is The Working Principle Of HDPE Insulation Pipe Production Line?

The working principle of the HDPE insulation pipe production line mainly involves the following key steps:

1. Raw material preparation and transportation: high-density polyethylene

(HDPE) particles are transported to the extruder through an automatic feeding system, which is usually equipped with a drying system to ensure the drying of raw materials and avoid the impact of moisture on product quality.

2. Extrusion molding: The raw material is heated and plasticized in the extruder, and the molten HDPE is uniformly extruded through an efficient screw extruder to form a tubular shape. The unique mold design used in the production line ensures stable extrusion pressure and uniform thickness of thin-walled tubes.

3. Vacuum sizing and cooling: The extruded tube passes through the vacuum styling tank, and it is shaped by vacuum adsorption to ensure the accuracy of the pipe diameter and wall thickness. The tube is then cooled into the spray cooling tank to solidify its shape.

4. Traction and cutting: the cooled pipe is pulled by the tractor at a constant speed to ensure the continuity of the production process. When the pipe reaches the predetermined length, the cutting machine automatically cuts to complete the production of a single pipe.

5. Stacking and quality control: the pipe after cutting is collected by the stacking rack, and the PLC control system monitors the production process throughout the process to ensure the accuracy of each step and the consistency of the product.

Through this series of steps, the HDPE insulation pipe production line can efficiently and stably produce high-quality insulation pipes, which are widely used in heating, chemical industry, central heating and other fields.
