PE aluminum-plastic composite panel production line, customized solutions meet diverse production needs

Qingdao EASTSTAR's complete PE aluminum-plastic panel production line consists of an SJ150×33 single-screw extruder, a composite die, a three-roll calender, a double-sided aluminum coil unwinder, a two-roll thermal laminator, an eight-roll thermal laminator, a six-roll cooling guide roll stand, a laminator, a four-roll haul-off, and a cutter. A PLC system enables intelligent control of the entire line.

The SJ150×33 single-screw extruder, the core equipment of this PE aluminum-plastic panel production line, boasts numerous technological advantages. The extruder's screw and barrel are made of 38CrMoAlA material and undergo a nitriding treatment, achieving a nitrification depth of 0.50-0.70 mm, ensuring wear resistance and stability under long-term high-speed operation. The extruder is equipped with seven heating zones and a heating power of 42 kW, achieving a maximum extrusion output of 800 kg/hour, meeting the needs of high-efficiency production. The main motor uses a 160 kW Siemens AC motor, coupled with a helical gear reducer, enabling stepless speed regulation from 0 to 70 rpm.

                                                                                                                              Precision configuration ensures product quality.                                                                                                                                                     

The production line's composite die head features a T-shaped structure and is manufactured from P20 mold steel, with a flow channel surface roughness of Ra 0.05 μm. The die head has nine heating zones, a heating power of 27 kW, and a maximum production width of 1,300 mm, enabling precise control of the extruded PE core layer's thickness and flatness. The three-roll calender has an effective working surface dimension of 500 × 1,500 mm. The line speed can be precisely adjusted from 0.5 to 8 m/min using an ABB variable speed control system, ensuring a smooth sheet surface.

The two-roll thermal laminator utilizes a combination of rubber and steel rollers, measuring 320 × 1,480 mm. An automatic hot oil heating system ensures precise temperature control. The coordinated operation of the eight-roll laminating unit and the six-roll cooling and setting machine further ensures the smoothness and bonding strength of the aluminum-plastic panel during the lamination process. The entire line is equipped with a vacuum dehumidification system, achieving a vacuum level of -0.04 MPa, effectively removing moisture from the raw materials and preventing defects such as bubbles in the finished product.

                                                                                                                                          Customized Services Meet Individual Needs                                                                                                                                                

To meet the specific requirements of different customers, PE aluminum-plastic panel production lines offer non-standard customization services. Parameters such as line width, number of laminating layers, and heating methods can be adjusted to meet customer needs. The equipment's modular design allows for flexible configuration based on factory conditions and production processes. The Siemens PLC control system enables automated operation of the entire line, significantly reducing manual operation.

As the construction industry's requirements for decorative materials continue to rise, technological advancements in PE aluminum-plastic panel production lines will continue to drive improvements in product quality. Equipment manufacturers are helping aluminum-plastic panel manufacturers gain a broader market share by continuously optimizing equipment performance and providing customized solutions.
