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

When architectural aesthetics collide with digital technology, double-curved GRC forms are reshaping city skylines with astonishing visual impact. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group has witnessed how digital mold technology has broken through traditional process bottlenecks, turning architectural curves once deemed unachievable from drawings into reality.

Digital Technology Breakthroughs in Double-Curved GRC Forms: From Geometric Challenges to Precise Realization

Traditional GRC mold making relies on manual mold casting, which often results in dimensional deviations and insufficient surface precision when dealing with complex shapes such as double-curved surfaces. Digital mold technology, through the synergy of parametric design (such as the Rhino+Grasshopper platform), 3D scanning, and BIM modeling, transforms designers' creative concepts into quantifiable digital models. Taking a double-curved curtain wall project at a cultural center as an example, Qinglong's technical team used digital twin technology to simulate the stress deformation of components, controlling mold errors within ±0.5mm—a 300% improvement in precision over traditional processes—and perfectly achieving the "flowing curved surface" effect required by the architects.

Full-Chain Digital Empowerment: Seamless Integration from Design to Installation

The digital mold technology system built by Qinglong Group covers the entire process from detailed design to after-sales maintenance. On the production side, a composite process combining CNC engraving and 3D printing solves the rapid prototyping challenge of double-curved molds; on the construction side, 3D laser scanning and modular installation technology enable "zero-error" assembly of complex components. This technical approach not only shortens the production cycle by 40% but also raises material utilization to over 95%, reducing overall costs for clients. Notably, the Technical Standard for Architectural Application of Glass Fibre Reinforced Cement (GRC) (JGJ/T423-2018), which Qinglong participated in formulating, has incorporated digital mold technology as a recommended process, driving technological upgrades across the industry.

Technological Innovation in Engineering Practice: Proven Strength Through Projects

In the renovation project of Century Plaza on Nanjing East Road, the Qinglong team applied a composite technology of translucent concrete and double-curved GRC to create an artistic curtain wall that is crystal clear by day and flows with light and shadow by night. The project used digitally molded precast components, achieving a weight of only 85kg per square meter (one-quarter that of traditional stone) and doubling installation efficiency, winning the Silver Award of the First UHPC Construction Engineering Innovation Award (AALBORG WHITE Cup). Similar cases confirm the core advantages of digital mold technology in achieving aesthetic effects, controlling costs, and ensuring safety, while also demonstrating Qinglong's technical accumulation as a National High-tech Enterprise.

From classical European lines to modern double-curved skins, the development of GRC materials has always advanced in step with technological innovation. Building on 28 years of full-chain experience, Qinglong Group has deeply integrated digital mold technology into its UHPC/GRC/GRG/GRP product system, not only providing designers with greater creative freedom but also delivering solutions for owners that combine aesthetic value with economic benefits. In the future, as parametric design and intelligent manufacturing become more deeply integrated, double-curved GRC forms will shine in more landmark buildings, and Qinglong will continue to pursue its mission of "Creating Beautiful Architecture," pushing forward the boundaries of new architectural decorative material technology.
