How to Improve the Production Efficiency of Double-Curved GRC Panels: Analysis of Key Technologies and Optimization Strategies

In the field of architectural decoration materials, balancing efficiency and quality has always been a core issue in industry development. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group understands that improving the production efficiency of double-curved GRC panels not only concerns corporate competitiveness, but also directly affects the realization of designers' creativity and project delivery timelines. This article will analyze the key paths to improving double-curved GRC panel production efficiency from three dimensions—technological breakthroughs, process optimization, and intelligent upgrading—providing practical solutions for the industry.

I. Material and Process Innovation: The Technical Foundation for Double-Curved GRC Panel Production Efficiency

Improving the production efficiency of double-curved GRC panels relies first on breakthroughs in material formulations and molding processes. Through 28 years of technical accumulation, Qinglong Group has developed high-performance glass fiber reinforced cement composite materials with a flexural strength exceeding 20MPa, significantly reducing molding difficulty while maintaining the panels' thin and lightweight characteristics (weighing only 1/4 of traditional stone). To address the complexity of double-curved shapes, 3D scanning and parametric design technology (Rhino+Grasshopper platform) is adopted, shortening the traditional manual modeling cycle by 50% and achieving seamless transformation from design drawings to production molds. In mold technology, the innovative use of reusable flexible silicone molds, combined with an automated grouting system, has compressed the production cycle of a single double-curved panel from 72 hours to 48 hours, while reducing the mold loss rate by 30%, greatly improving material utilization and production continuity.

II. Full-Process Intelligent Management: Building an Efficient Production System for Double-Curved GRC Panels

Efficiency improvement is inseparable from refined management across the entire chain. Leveraging its national-level R&D center and provincial engineering technology center, Qinglong Group has built an integrated intelligent management platform covering "design-production-installation." In the detailed design phase, BIM technology integrates structural mechanics analysis with production process parameters, proactively avoiding shape conflicts and process difficulties and reducing rework rates during production. In the production stage, industrial robots are introduced for automatic material distribution, vibration, and curing. Combined with an RFID chip traceability system, real-time monitoring of production data for each double-curved GRC panel is achieved, keeping the defect rate below 0.5%. To meet the concentrated delivery needs of large projects, modular production and parallel operation modes are adopted. For example, in the Nanjing East Road Century Plaza renovation project, multi-line synchronized production and optimized logistics scheduling shortened the delivery cycle of 12000㎡ double-curved light-transmitting GRC panels by 25%, setting the industry's fastest record for similar projects.

III. Industry Collaboration and Standards Leadership: Ecosystem Empowerment for Double-Curved GRC Panel Efficiency Improvement

As a vice-chairman unit of the China GRC Association and a participant in drafting the "Technical Standard for Architectural Application of Glass Fiber Reinforced Cement (GRC)" (JGJ/T423-2018), Qinglong Group understands the driving role of industry standards in efficiency improvement. By joining hands with universities and peer enterprises (such as Guangdong Shiji Shangpin and Shantaixin Industrial) to build technology innovation alliances and share mold optimization solutions and production management experience, it promotes the standardization and modularization of double-curved GRC panel production. Meanwhile, in response to the core needs of designers and owners, it provides "customized design + full-cycle technical support" services. For example, in the Dongguan Women and Children's Activity Center project, early involvement in the design phase kept the installation precision of double-curved GRC exterior wall panels within ±2mm, achieving "zero-error" jointing and indirectly reducing the overall project schedule cost.

Improving the production efficiency of double-curved GRC panels is a comprehensive result of material technology, intelligent manufacturing, and industry collaboration. With the mission of "creating beautiful architecture," Qinglong Group, through continuous technological innovation and full-chain service optimization, not only provides efficient solutions for high-end architectural projects (such as grand theaters, commercial complexes, and landmark buildings), but also drives the high-quality development of the UHPC/GRC/GRG/GRP materials industry. In the future, with the in-depth application of digitalization and green production technologies, double-curved GRC panels will play an even greater role in balancing artistic aesthetics and engineering efficiency, injecting new vitality into the field of architectural decoration.
