Principles and Application Research of Digital Mold Technology for Double-Curved GRC Shaping

Driven by the dual forces of contemporary architectural aesthetics and engineering technology, double-curved forms have become an important language for landmark buildings to express their unique character. As an industry leader with 28 years of experience in in-depth design and full-chain services for UHPC/GRC/GRG/GRP materials, Qinglong Group deeply understands the revolutionary significance of digital mold technology in realizing double-curved GRC forms. From the shell roof of the Sydney Opera House to the "rounded pebbles" of the Guangzhou Opera House, double-curved GRC is redefining the possibilities of building envelopes with its lightweight, high-strength, and free-form characteristics, and digital mold technology is the core engine driving this transformation.

Double-Curved GRC Digital Mold Technology: Full-Process Innovation from Parametric Design to Intelligent Production

Traditional production of double-curved GRC components relies on manual mold making, suffering from low precision, long cycles, and high costs. Digital mold technology, through a closed technical loop of 3D scanning, parametric modeling, and CNC machining, achieves precise transmission of form data. Leveraging the R&D strength of its provincial-level engineering technology center, Qinglong Group deeply integrates BIM technology with the Rhino/Grasshopper parametric platform, enabling modeling of double-curved forms with a minimum curvature radius of 300mm, and producing high-precision master molds through five-axis machining centers, keeping component dimensional errors within ±2mm. This technical approach not only solves the forming challenges of complex double-curved forms, but also shortens mold production cycles by 40%, providing technical assurance for mass production of large-scale projects.

The Synergy of Materials Science and Digital Technology: The Balancing Art of GRC Performance Optimization and Form Realization

Realizing double-curved GRC forms requires not only advanced mold technology, but also precise control of material properties. As a co-authoring unit of the Technical Standard for Building Application of Glassfibre Reinforced Cement (GRC), Qinglong achieves stable flexural strength above 20MPa for double-curved components by adjusting glass fiber content (typically 4-5%) and optimizing mix design, while maintaining a lightweight characteristic of 800-1200kg/m³. In the Dongguan Women and Children's Activity Center project, the double-curved GRC curtain wall panels produced with digital mold technology both satisfied the architect's aesthetic pursuit of flowing surfaces and ensured structural safety through material mechanics calculations. The project won the Silver Award at the first GRC Construction Engineering Innovation Awards, becoming a model of the integration of technology and art.

Technical Breakthroughs in Engineering Practice: Full-Chain Solutions from Design to Installation

Implementing double-curved GRC forms is a systematic project requiring seamless coordination among design development, production and manufacturing, and construction and installation. Qinglong Group innovatively adopts "digital twin" technology. In the Nanjing Road Century Plaza renovation project, 3D laser scanning was used to digitally model the installation base surfaces, simulating in advance the installation positioning of double-curved translucent GRC components. Combined with customized metal connector design, "zero-error" splicing of complex curved surfaces was achieved. This full-process digital management model improved project installation efficiency by 30%, while a quality traceability system based on embedded RFID chips was established to provide data support for later maintenance, fully demonstrating the technical depth of a national high-tech enterprise.

As architectural creation places increasingly demanding requirements on formal expression, digital mold technology for double-curved GRC forms is becoming a core competitiveness in the high-end building sector. Building on 28 years of accumulated industry experience, Qinglong Group will continue to promote the deep integration of digitalization and materials science, providing designers with full-chain solutions from concept to realization. Whether the artistic curved surfaces of cultural venues or the dynamic envelopes of commercial complexes, Qinglong always upholds the mission of "creating beautiful architecture," using technological innovation to bring more architectural aesthetic visions to reality, and is committed to becoming a world-class leading UHPC/GRC/GRG/GRP manufacturing enterprise.
