This technology involves melting and extruding PE granules and forming them, and includes an extruder, die, cooling system, sizing device, traction device, and cutting device. With increasing demands for energy conservation and intelligent manufacturing, extrusion equipment is gradually developing towards higher efficiency, energy saving, and intelligent operation. Multi-layer co-extrusion technology is also being applied to improve the quality and functionality of pipes. In the future, PE pipe extrusion technology will play a role in even more fields.
