Evaluation indicators for the selection of solar photovoltaic module laminators

Oct 18, 2025

Key performance and technical parameters are at the core of evaluating the quality of the laminator.
1. Temperature uniformity: This is the most important indicator. The temperature difference at each point inside the cavity should be controlled within ±1.5℃. Excessive temperature differences can cause serious problems such as warping, bubbling and delamination of components.
2. Pressure control accuracy: The lamination process requires precise vacuum and pressure curves. The system should be capable of stably maintaining a high vacuum degree, and the pressurization process should be smooth and adjustable.
3. Control System:
A. PLC (Programmable Logic Controller) : Brand and performance are key.
B. HMI (Human-Machine Interface) : Whether the operation is simple and convenient, and whether multiple sets of process formulas can be stored and called up to adapt to different products.
C. Data Recording and Traceability: Can the lamination time, temperature and pressure curves of each component be recorded to facilitate quality traceability and problem analysis?
4. Heating method:
A. Electric heating: Precise control, simple structure, clean, but relatively high operating cost.
B. Oil heating: It requires an external thermal oil furnace, making the system complex, but the operating cost may be lower.
C. Lamination cycle: The time from feeding to discharging to complete one cycle. The shorter the cycle, the higher the production capacity per unit time.
5. Core component brand:
A. Vacuum pump: It is the key to energy consumption and reliability.
B. Seals and cylinders: They are related to the long-term stability and vacuum retention capacity of the equipment.
C. Sensors: Ensure the accuracy of data collection.
