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

In the field of architectural decorative materials, efficiency is the core of enterprise competitiveness. As an industry expert with 28 years of deep engagement in UHPC/GRC/GRG/GRP materials, Qinglong Group fully understands the critical significance of improving the production efficiency of double-curved GRC panels for project delivery. Thanks to their unique curved surface design advantages, double-curved GRC panels are widely used in high-end buildings such as grand theaters and commercial complexes, but complex production processes often become an efficiency bottleneck. From the dual perspectives of technological innovation and management optimization, this article explores how to break through production constraints and achieve efficient intelligent manufacturing of double-curved GRC panels.

I. Technological Innovation: Decoding the Production Processes of Double-Curved GRC Panels

Improving the production efficiency of double-curved GRC panels first depends on breakthroughs in material formulations and forming processes. Through 28 years of technical accumulation, Qinglong Group has developed unique advantages in material modification: by combining high-purity alkali-resistant glass fibers with special cement, it has developed a high-performance GRC substrate with flexural strength exceeding 20MPa. Combined with its proprietary patented modified additives, material fluidity has increased by 30%, greatly shortening pouring and forming time. In terms of forming processes, the introduction of 3D scanning and parametric design technology has reduced traditional manual mold-flipping errors from ±5mm to ±2mm; in a landmark project, the production cycle of double-curved curtain wall panels was shortened by 40% compared to the industry average.

Innovation in mold technology is equally critical. To address the complexity of double-curved shapes, Qinglong has developed a modular adjustable mold system. Through combinations of CNC-machined aluminum alloy modules, it enables rapid switching between different curvature radii (down to a minimum of 300mm), increasing mold reuse rates to over 85%. In the Nanjing East Road Century Plaza renovation project, this technology successfully achieved standardized production of 3,000㎡ of double-curved light-transmitting GRC panels, saving 60% in mold costs compared to traditional wooden mold processes and compressing the construction period by 50 days.

II. Management Optimization: Building an Efficient, Fully Coordinated Production System

Improved production efficiency is inseparable from the support of a scientific management system. Qinglong Group has established a full-chain digital management platform covering everything from detailed design to after-sales maintenance, using BIM technology to seamlessly connect design parameters with production data. In the Dongguan Women and Children's Activity Center project, pre-assembly simulations using BIM models identified and resolved 12 complex node conflicts in advance, improving on-site installation efficiency by 35%.

The implementation of lean production concepts is another engine driving efficiency improvements. At its production base in Nanning, Guangxi, Qinglong has adopted a "cellular production model," breaking down double-curved GRC panel production into standardized units such as mold preparation, material mixing, pouring and forming, and curing and demolding, with an intelligent dispatching system matching the rhythm of each stage. Data shows that this model has increased production site utilization by 25% and per capita output by 40%, achieving efficient operation at an annual capacity of 600,000 square meters.

III. Industry Empowerment: Leading GRC Industry Upgrading with Technological Strength

As a co-contributor to the Technical Standard for the Application of Glass Fiber Reinforced Cement (GRC) in Buildings, Qinglong Group has always driven industry progress through technological innovation. To address common challenges in double-curved GRC panel production, the company's "digital production line for double-curved components" was selected as a Ministry of Housing and Urban-Rural Development scientific and technological achievement promotion project, and its core technologies have passed the Guangdong Province scientific and technological achievement appraisal. The production line integrates advanced equipment such as automated material distribution, robotic spraying, and intelligent curing, raising the production yield of complex double-curved components from 75% to 98% and setting a new industry benchmark for efficiency.

From material R&D to intelligent manufacturing, from process innovation to management upgrades, Qinglong Group, grounded in 28 years of full-chain experience, continues to explore breakthrough paths for improving the production efficiency of double-curved GRC panels. In the future, as demand for personalized architectural decoration grows, double-curved GRC panels will shine in more landmark projects, and the dual improvement of efficiency and quality is the best practice of Qinglong's mission to "create beautiful architecture" as an industry leader.
