The 70/80 Photovoltaic Double-Layer String Extrusion Production Line is a high-efficiency manufacturing solution designed for the precise production of photovoltaic string products with a double-layer structure. Built for modern solar component fabrication, this production line combines stable extrusion performance, accurate material control, and continuous automated operation to meet the demanding quality requirements of the photovoltaic industry.This production line is typically used to produce insulated or encapsulated string materials that are essential in solar energy applications. The double-layer extrusion design allows two different materials to be processed and formed simultaneously, creating a composite structure with improved mechanical strength, better electrical insulation, and enhanced environmental resistance. This is especially important for photovoltaic products that must perform reliably under long-term outdoor exposure, including high temperatures, UV radiation, humidity, and mechanical stress.One of the key advantages of this line is its high-precision extrusion system. The 70/80 configuration provides excellent compatibility with different raw materials and production requirements, offering stable output and uniform layer thickness. The optimized screw and barrel design ensures thorough plasticization of materials, smooth flow, and consistent product quality. In addition, the extrusion system is engineered to reduce material waste and improve energy efficiency, helping manufacturers lower operating costs while maintaining high production standards.The line is equipped with advanced temperature control, speed synchronization, and tension regulation systems. These functions work together to maintain accurate process conditions throughout production, ensuring that each layer is formed with precision and that the final product meets strict dimensional and performance specifications. The integrated control system also supports easy operation and monitoring, allowing operators to adjust parameters quickly according to different production needs.Another notable feature is its automation capability. From feeding and extrusion to cooling, traction, and winding, the production process can be managed efficiently with minimal manual intervention. This not only improves productivity but also reduces the risk of human error, enhancing product consistency and reliability. The line is designed for continuous operation, making it suitable for large-scale photovoltaic manufacturing environments where stability and output efficiency are critical.The double-layer structure produced by this line offers significant functional benefits. The outer layer can provide protection against abrasion, weathering, and mechanical impact, while the inner layer can ensure electrical insulation or improve bonding properties depending on the application. This multilayer approach makes the final product more durable and adaptable for use in solar module assembly and related photovoltaic systems.With its compact layout, reliable performance, and flexible production capability, the 70/80 Photovoltaic Double-Layer String Extrusion Production Line is an ideal choice for manufacturers seeking to improve product quality and production efficiency. It represents a practical and advanced solution for the growing demand in the renewable energy sector, supporting the development of high-performance photovoltaic products with consistent and stable manufacturing output.
