Empowering the Future of the PV Industry Through Laminator Technology Innovation

At this pivotal moment of the PV industry's transition toward higher efficiency and intelligence, laminators—as core equipment for module encapsulation—play a decisive role in determining PV module yield rates and power generation efficiency. ChinTiyan New Energy has become an industry benchmark for technological advancement through its independently developed laminator technology. Featuring high-precision temperature control, dynamic pressure regulation, and end-to-end automation solutions, the company is propelling photovoltaic manufacturing toward a new era of high-quality development.

Technological Breakthrough: Comprehensive Innovation from Material Compatibility to Process Closed-Loop Control

Laminator employs an electric heating system with PID closed-loop control technology. Through 40 independent temperature control points, it achieves temperature uniformity ≤±1℃, meeting the process parameter-sensitive material requirements for thin-film cells, flexible modules, and other applications. The heating plates are crafted from high-thermal-conductivity aluminum alloy. Combined with zone-specific control and density gradient design, this prevents EVA film degradation or hidden cracks in cells caused by localized overheating. It ensures precise matching of thermal expansion coefficients for encapsulation materials throughout preheating, lamination, and curing stages.

The pressure system employs dual-mode hydraulic and pneumatic drive. The hydraulic system achieves pressure deviation ≤±1% through multi-cylinder synchronized motion, with pressure retention stability maintaining fluctuations ≤±2% over several hours. This ensures uniform compaction for novel structures like double-glass modules and perovskite tandem cells. The pneumatic system offers cost advantages for small-scale production lines, accommodating diverse manufacturing needs. The equipment supports dynamic vacuum adjustment from 100 to 40 Pa. Combined with a compressed air flow rate of 1200 L/min, it rapidly removes air and moisture between materials, reducing module breakage rates to below 0.3%.

Parameter Analysis: Defining Efficient Production Standards Through Data

The core parameter design of laminators directly addresses industry pain points:

• Temperature Control Precision: ±1℃ temperature uniformity, supporting multi-stage temperature curve settings to accommodate process requirements for different materials like monocrystalline silicon and thin-film cells;

• Pressure Stability: Hydraulic systems deliver thousands of tons of stable pressure, while pneumatic systems enable rapid response, meeting cross-scenario applications from lab R&D to mass production;

• Production Efficiency: Single lamination cycles reduced to 6.5-20 minutes—a 30% improvement over traditional equipment. Combined with fully automated loading/unloading systems, achieving annual production capacity of 500MW per line;

• Energy Consumption Control: Far-infrared heating system boosts thermal efficiency by 20% while reducing energy consumption by 15%, compliant with EU CE certification and domestic green manufacturing standards.

As demonstrated by a leading photovoltaic enterprise, the introduction of ChinTiyan New Energy laminators elevated double-glass module encapsulation yield from 92% to 98.5%. Optimized structural stability boosted power generation efficiency by 1.2%, while annual energy cost savings per production line exceeded RMB 500,000.

Industry Outlook: Technological Iteration Drives Paradigm Shift in PV Manufacturing

As next-generation technologies like N-type cells and perovskite tandem modules accelerate commercialization, PV modules impose higher demands on encapsulation equipment: thinner cells require more precise pressure control to prevent microcracks; more complex tandem structures rely on uniform temperature distribution to ensure interfacial bonding; and stricter reliability standards mandate equipment with full lifecycle data traceability.

ChinTiyan New Energy has initiated R&D for next-generation laminators, planning to implement real-time material deformation monitoring via AI vision systems and achieve intelligent process parameter optimization through digital twin technology. Its R&D team is collaborating with research institutions like Wuhan University and Hubei University of Technology to explore nanomaterials for heating plate thermal layers, aiming to achieve temperature control precision of ±0.5°C. Simultaneously, modular designs are being developed to accommodate encapsulation needs for novel cell types such as heterojunction (HJT) and IBC.

Driven by dual carbon goals and the global energy transition, the photovoltaic industry is shifting from scale expansion to quality-first development. It builds competitive barriers through deep technological expertise. Its laminators transcend mere production tools, becoming key engines propelling the industry toward high efficiency, intelligence, and sustainability. As China's PV equipment evolves from “manufacturing” to “intelligent manufacturing,” ChinTiyan is poised to secure more pivotal technological influence within the global supply chain.
