How to Improve the Production Efficiency of Double-Curved GRC Panels? Process Optimization and Qinglong Group's Intelligent Manufacturing System

Improving the production efficiency of double-curved GRC panels is a systematic engineering task that requires coordinated optimization across four dimensions: mold design, material formulation, production processes, and organizational management. Through 28 years of practice, Qinglong Group has built a highly efficient production system featuring "modular design, standardized processes, parallelized operations, and intelligent control," reducing the average production cycle of double-curved panels from the traditional 45 days to 25 days. In the Hainan International Convention and Exhibition Center project, we achieved a daily output of 120 double-curved panels by optimizing mold design (reducing mold types by 30%), improving material formulations (shortening curing time), and implementing assembly-line operations, meeting the schedule requirements for a 120,000-square-meter roof. Efficiency improvement is a comprehensive reflection of technical accumulation and management innovation.

Mold Optimization Is the First Step in Improving Efficiency

Parametric design breaks down double-curved surfaces into reusable standard units, greatly reducing the number of molds. We developed a combined mold system in which base modules can quickly swap profile liners, achieving "one mold, multiple uses." In the Wuhan Hanxiu Theater project, modular design reduced the number of molds from an estimated 300 sets to 80 sets, cutting mold costs by 40%.

Material Innovation Shortens Process Cycles

We developed a rapid-hardening GRC mix with an initial setting time controlled at 45 minutes and demolding time shortened to 8 hours. Using a low-temperature steam curing process (60°C × 12h), the strength development rate increased 3-fold while energy consumption dropped by 20%. The intelligent curing kilns at the Nanning production base enable precise temperature control, with a curing pass rate of 99.9%.

Process Reengineering and Automation

Traditional sequential operations were converted to parallel operations: mold preparation, reinforcement fabrication, and slurry mixing proceed simultaneously. Robotic spraying systems were introduced, delivering 5 times the efficiency of manual work with stable quality. One of our automated production lines requires only 6 operators and achieves a daily output of 200 square meters.

Digital Management Enables Full-Process Optimization

The MES production execution system monitors the time consumption and quality data of every stage in real time. Big data analysis identifies bottleneck processes for continuous optimization. Through system optimization, the Shenzhen Pingshan project increased capacity by 35% and shortened delivery times by 30%.

There is no end to improving production efficiency. Through continuous technical innovation and management optimization, Qinglong Group makes it possible to produce even complex double-curved GRC panels at scale and economically.
