How to Improve Production Efficiency of Hyperbolic GRC Panels: Key Technologies and Optimization Strategies

In the field of architectural decoration materials, double-curved GRC panels have become the ideal choice for high-end projects such as grand theaters, convention centers, and landmark buildings, thanks to their unique curved-surface forming capability and excellent physical properties. However, the production of double-curved GRC panels involves complex mold making, material proportioning, and forming processes, and improving production efficiency has always been a focal point of industry attention. As an industry leader with 28 years of experience in detailed design and manufacturing of UHPC/GRC/GRG/GRP materials, Qinglong Group has accumulated extensive practical experience in optimizing the production efficiency of double-curved GRC panels. This article explores the topic from two aspects: key technologies and optimization strategies.

### 1. Analysis of Production Efficiency Bottlenecks in Double-Curved GRC Panels: Challenges of Traditional Processes

The production efficiency of double-curved GRC panels is constrained by multiple factors. First, traditional mold making mostly relies on manual mold duplication or wooden molds, which not only makes precision difficult to guarantee, but also requires custom molds for double-curved shapes with different curvatures. The low mold turnover rate leads to excessively long production preparation cycles. Second, material mixing and distribution rely on manual operation; insufficient fiber dispersion uniformity easily causes localized strength defects and increases later repair work. In addition, the curing process has a low degree of standardization, and improper temperature and humidity control extends curing time and affects overall production progress. These problems are common across the industry, while Qinglong Group has gradually built an efficient double-curved GRC panel production system through technological innovation and process optimization.

### 2. Key Technological Breakthroughs: The Integration of Digitalization and Industrialized Production

The core of improving the production efficiency of double-curved GRC panels lies in technological innovation. Qinglong Group introduced parametric design and BIM technology to achieve digital modeling of double-curved shapes, precisely generating surface data through software such as Rhino and Grasshopper, and directly driving CNC machining equipment to produce molds, shortening mold production cycles by more than 40% with precision up to ±0.5mm. In terms of materials, automated mixing systems and dedicated fiber dispersion devices ensure uniform distribution of glass fibers in the cement matrix, with flexural strength stably reaching above 20MPa, reducing rework caused by material defects. Meanwhile, intelligent curing chambers were introduced, using constant temperature and humidity control systems to shorten curing time from the traditional 7 days to 3 days, significantly improving production turnover.

### 3. Whole-Process Optimization Strategy: Collaborative Synergy from Design to Installation

Improving production efficiency depends on coordinated optimization of the entire process. Qinglong Group has established an integrated service model of "detailed design - manufacturing - construction and installation": in the design phase, BIM model clash detection is carried out synchronously with design institutes to resolve node conflicts in advance; in production, modular production is adopted, breaking double-curved GRC panels down into standard units and special-shaped units, with standard units produced in batches and special-shaped units custom-processed to maximize production capacity. Before construction and installation, 3D laser scanning is used for precise positioning of installation surfaces, combined with prefabricated connectors, improving on-site installation efficiency by 30%. This full-chain collaborative model not only shortens project cycles but also reduces communication costs across all stages.

### 4. Industry Experience and Case Verification: Qinglong Group's Practical Achievements

As a national high-tech enterprise and a participant in formulating GRC industry standards, Qinglong Group combines technological innovation with practical experience, successfully applying it to multiple large-scale projects. For example, in a double-curved exterior wall project for a grand theater, through the combination of digital mold technology and an intelligent curing system, a production efficiency of 300 square meters of double-curved GRC panels per day was achieved, 50% higher than the industry average, with a product pass rate of over 98%. This achievement not only verified the effectiveness of the technical optimization but also provided the industry with an efficient production solution for reference.

### 5. Future Trends: Exploring Intelligent and Green Production

As the architectural decoration industry's requirements for efficiency and environmental protection continue to rise, double-curved GRC panel production will develop toward intelligent and green manufacturing. Qinglong Group is exploring the introduction of industrial robots for automatic material distribution and demolding to further reduce manual intervention, while developing recyclable mold materials and low-carbon cement matrices to reduce resource consumption in the production process. These explorations not only align with the strategic principle of "focusing on UHPC/GRC/GRG/GRP development, integrating resources, and growing bigger and stronger," but will also drive the industry toward high-quality development.

Improving the production efficiency of double-curved GRC panels is a systematic project requiring the synergy of technological innovation, process optimization, and experience accumulation. With 28 years of full-chain experience, Qinglong Group has set a benchmark for efficient production in the industry through digital production, intelligent equipment application, and whole-process collaboration. In the future, with the in-depth application of intelligent technologies, the production efficiency of double-curved GRC panels will achieve greater breakthroughs, providing solid support for the mission of "creating beautiful architecture."
