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

In the field of contemporary architectural decoration, double-curved GRC panels have become the preferred material for high-end projects such as landmark buildings and cultural venues, thanks to their unique curved aesthetics and structural performance. However, their complex forming processes often create production efficiency bottlenecks, and how to break through this limitation has become a topic of common concern across the industry. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP, Qinglong Group has drawn on the practice of hundreds of complex projects to deeply explore the core paths for improving the production efficiency of double-curved GRC panels, providing the industry with practical technical solutions and management strategies.

I. Analysis of the Core Constraints on Double-Curved GRC Panel Production Efficiency

The production efficiency of double-curved GRC panels is affected by multiple factors, with the primary bottleneck lying in mold development and forming processes. Traditional wooden or GRP molds suffer from insufficient precision and low turnover (typically only 10-15 uses); in particular, for the complex curvature of double-curved surfaces, mold adjustment often accounts for more than 30% of the total production cycle. Second, material mix proportions and mixing processes directly affect product consistency—manual proportioning easily leads to uneven fiber dispersion, causing later strength fluctuations and increasing rework rates. In addition, the production process lacks digital coordination, with information gaps between design development, mold machining, forming and curing, further extending delivery times.

II. Key Technological Breakthroughs: From Mold Innovation to Intelligent Forming

Technological innovation is the core driving force for improving the production efficiency of double-curved GRC panels. In mold technology, Qinglong Group has combined 3D scanning with CNC machining to develop a high-precision adjustable steel mold system, raising mold turnover to more than 50 uses, while modular design enables rapid reconfiguration of molds with similar curvatures, cutting mold development time by 40%. In material processes, the introduction of an automated proportioning system and high-speed shear mixing technology ensures uniform dispersion of glass fibers (with fiber length deviation controlled within ±2mm); combined with a specially modified cement-based material, product curing time has been compressed from the traditional 28 days to 14 days, while flexural strength remains stable at above 20MPa.

The application of intelligent forming technology further unlocks production capacity. Through the combination of BIM parametric design and robotic lamination technology, the forming precision of double-curved panels is controlled within ±3mm, with efficiency 3 times higher than manual lamination. For complex double-curved shapes, a "pre-forming + on-site assembly" process breaks oversized components down into standardized modules, reducing transportation difficulty while enabling assembly-line production. In one cultural center project, the production cycle for a 3,000㎡ double-curved GRC curtain wall was shortened to 45 days, 50% faster than the industry average.

III. Full-Process Optimization Strategies: Collaborative Efficiency Gains from Design to Delivery

Improving production efficiency also depends on full-chain management optimization. At the design stage, Qinglong Group uses the Rhino+Grasshopper parametric platform to simulate the formability of double-curved panels in advance, reducing rework caused by design changes. For production planning, an MES system performs intelligent scheduling with real-time monitoring of mold status, material inventory, and equipment utilization, raising overall equipment effectiveness (OEE) to above 85%. In quality control, RFID chip traceability technology records production data from raw materials to finished products; combined with an AI visual inspection system, the product pass rate has been raised from 92% to 98%, greatly reducing efficiency losses caused by defective products.

As a national high-tech enterprise and a participant in formulating GRC industry standards, Qinglong Group has always driven industrial upgrading through technological innovation. Through mold innovation, intelligent forming, and full-process coordination, the production efficiency of double-curved GRC panels has achieved a qualitative leap—not only meeting modern architecture's demand for complex shapes, but also, through an integrated "design-production-construction" service model, providing designers and owners with full-cycle solutions from concept to realization. In the future, as digital and green manufacturing technologies become deeply integrated, double-curved GRC panels will inject more possibilities into the architectural decoration industry by balancing efficiency and aesthetics.
