  18. The height of the equipment worktable is 850mm ± 50mm;
  19. The customized high-temperature resistant servo motor automatically lifts the backplate close to the surface of the backplate of the solar panel, and the vacuum straw absorbs the backplate. The lifting distance can be adjusted through the parameters set on the man-machine interface;
  20. It is controlled by computer + PLC, which can save a variety of parameter settings and program calls;
  21. The temperature control adopts SSR + PID control mode, with temperature control accuracy of ± 1 ℃; The temperature control part is controlled by solid-state relay;
  22. Size of removable battery panel: L500 * w500-l1100 * w2100mm (vacuum adsorption tube clamp or claw clamp shall be customized according to the specific size and the price shall be calculated separately except those included with the purchase);
  23. Body size: l1800 * w3600 * h2200mm (subject to the actual size);
  24. Emergency stop, safety protection device, high temperature, electrified and other safety warning signs;
  25. The size of the attached vacuum pipette clamp and claw clamp is 1000 mm, which can meet the film tearing of the 985mm wide backplate;
  26. The plate entry device provided by the buyer must have the function initially determined, and the deviation of initial positioning shall be ≤ 3mm.

Features of China Gwell’s PVDF PP Solar Panel Extrusion Line


  1. Extruder: China Gwell, as an Extruder Supplier, uses a single-screw extruder for PVDF PP, the temperature difference between the screw and barrel is ±1°C, and the circulating water cooling system ensures the uniform thickness of PVDF in the longitudinal direction. And better plasticization and non-crosslinking.
  2. T-die: Manual T-die can modify the PVDF PP plate thickness because the Fluid speed influences the thickness. China Plastic Extruder Supplier – GWELL can use high precision T-die and well-known brands.
  3. Calendar: The strength of the roller shall ensure that the temperature fluctuation accuracy of the roller surface is ≤± 1 degree, and the straightness and radial runout of the roller surface are ≤± 0.01mm.The roller body adopts double-sided embossing and solves the technical difficulties of the sheet sticking to the roller.
  4. Cooling bracket: A cooling bracket at a distance cools the PVDF PP plate better.
  5. Conveyor: Move the plate from one side to another side.
  6. Stacker: Accumulate some plates then move to the other side.
  7. Automatic operation: GWELL, as a China Plastic Extruder manufacturer, adopts PLC automatic control to realize human-machine interface operation, and the operation is simple and automatic.

The finished product of Gwell PVDF PP Solar Black Sheet Extrusion Line, used for solar back sheet. The solar backplane is located on the back of the solar panel, which plays a role in protecting and supporting the battery, and has reliable insulation, water-resistance, and aging resistance. At the initial stage, the solar backplane has a three-layer structure (PVDF / PET / PVDF), the outer protective layer PVDF has good environmental erosion resistance, the middle layer is PET polyester film, which has good insulation performance, and the inner PVDF and Eva have good adhesion performance. Later, in order to reduce costs and consider environmental protection, some fluorine-free backplane structures appeared, such as ape backplane.
