L'innovation en matière d'efficacité de la conception à double station de la machine laminée à sec à double station

Le Machine laminée à sec à double station occupe une position importante avec ses performances efficaces et stables, et son système précis de contrôle de la température et de pression est l'élément central pour garantir la qualité du laminage. Le laminage sous vide vise à obtenir une combinaison étroite de plusieurs couches de matériaux et est utilisé pour fabriquer divers produits composites. Sa qualité affecte directement les indicateurs clés du produit, tels que les propriétés mécaniques et l'isolation électrique. Qu'il s'agisse de la fabrication de circuits imprimés dans l'industrie électronique ou de la production de matériaux composites hautes performances dans le domaine aérospatial, un léger écart dans le contrôle de la température et de la pression lors du processus de laminage peut entraîner des problèmes tels qu'un délaminage du matériau, des bulles résiduelles ou une déformation excessive.
Mécanisme de réglage précis du système de contrôle intelligent de la température
Le temperature control system of the Dry double-station laminated machine adopts advanced intelligent control technology, which can accurately adjust the temperature according to the characteristics of different materials. The thermal stability, melting point and softening point of various materials vary significantly. The temperature control system monitors the temperature of the lamination environment in real time through the built-in sensor and compares it with the preset parameters. With the help of the PID (proportional-integral-differential) control algorithm, the power output of the heating element can be quickly and accurately adjusted. This process not only ensures that the material reaches the ideal melting or softening state during lamination, promotes the diffusion and fusion between molecules, but also effectively avoids the problem of material decomposition and carbonization due to excessive temperature, or loose interlayer bonding due to insufficient temperature, thus laying the foundation for high-quality lamination. ​
Principe de pression uniforme du système de contrôle de pression
Le pressure control system plays an indispensable role in the dry double-station laminated machine. Its core is to achieve uniform and stable pressure application. The system distributes the pressure evenly in the lamination area through precise hydraulic or pneumatic transmission devices. During the lamination process, every part of the material surface can be subjected to consistent pressure, prompting the material molecules to break through the obstacles of surface tension and fully penetrate into the adjacent layers. Taking the lamination of multiple layers of fiber fabrics and resin as an example, the pressure control system can ensure that the resin completely infiltrates the fibers, fills the gaps between layers, and eliminates bubbles and gaps. Precise control of pressure can also avoid material deformation and uneven thickness caused by excessive pressure, or loose interlayer bonding caused by insufficient pressure, further strengthen the interlayer bonding force, and improve the overall strength and stability of the composite material.​
Le synergistic operation efficiency of temperature control and pressure system​
Le temperature control and pressure control systems do not operate independently, but form a highly coordinated working mode in the dry double-station laminated machine. At the beginning of lamination, the temperature control system first raises the temperature to the processing range suitable for the material, so that the material has good fluidity and plasticity; the pressure control system starts synchronously to set the pressure and evenly apply pressure to promote the fusion between material molecules. During the lamination process, the two continue to dynamically adjust parameters according to the actual working conditions. For example, when the temperature fluctuates slightly, the pressure control system will make corresponding fine adjustments to maintain the stable bonding state of the material. This synergistic mechanism runs through the entire lamination cycle, from heating, insulation to cooling stages, ensuring that all links are closely coordinated to achieve perfect lamination of materials and effectively improve the yield and consistency of products. ​
Le superimposed advantages of double-station design and precise control​
Le unique double-station design of the dry double-station laminated machine, combined with precise temperature control and pressure control systems, further releases the efficiency of the equipment. The two stations can perform lamination operations alternately. While one station is performing vacuum lamination, the other station can complete preparations such as loading and parameter setting, which significantly shortens the production cycle. The precise temperature control and pressure control system ensures that the lamination quality of each station is always stable, and standardized production can be achieved regardless of changes in material batches.
