A manufacturing company specializing in curtain walls for supertall buildings and safety glass for high-end hotels faced a major challenge after securing a project for a landmark building in Southeast Asia: they needed to mass-produce extra-large laminated glass panels measuring 3m x 8m, requiring zero air bubbles, bulletproof-level impact resistance, and compliance with both REACH and CE certification standards, all within a delivery period of just 45 days. Their existing production equipment, due to insufficient precision in temperature and pressure control, resulted in an unacceptable bubble rate exceeding 8%, failing to meet project requirements. Ultimately, they opted for an upgrade to an intelligent temperature-controlled autoclave production line.

During project implementation, the core process flow was precisely executed:

1. Pre-treatment stage:

After ultrasonic cleaning and drying, the glass was precisely laminated with SGP high-strength interlayer film. A vacuum pre-pressing device was used to remove surface air, preventing residual bubbles in the interlayer;

2. Autoclave core treatment:

The laminated glass was placed into a 4m diameter, 15m long intelligent autoclave. A GPC three-phase power controller linked with a TK pressure sensor precisely executed a closed-loop "heating-pressurizing-constant temperature-cooling-depressurizing" process: heating to 145℃ to completely soften the interlayer film, pressurizing to 1.2MPa to ensure tight bonding between the film and the glass, maintaining constant temperature and pressure for 3 hours to ensure bonding strength, and finally slowly cooling and depressurizing to avoid stress concentration;

3. Post-treatment quality inspection:

The produced glass was inspected using professional equipment. The bubble rate was reduced to below 0.3%, and the impact resistance was improved by 3 times compared to the original process, fully meeting the project's bulletproof requirements.

The results of this application were significant: the intelligent temperature and pressure control technology of the autoclave not only solved the bonding problem of extra-large glass but also increased single-batch production efficiency by 40%, and the finished product pass rate jumped from 92% to 99.7%, successfully helping the company deliver the landmark project on time. Currently, the equipment has been operating stably for 18 months, and the laminated glass produced is widely used in high-end buildings, bank counters, and other applications. Thanks to its zero-defect quality and ultra-long durability, it has received repeat orders from international customers.
