Research on the Principles and Applications of Digital Mould Technology for Double-Curved GRC Shapes

When architectural aesthetics collide with digital technology, double-curved GRC shapes are reshaping the artistic expression of building envelopes with a disruptive stance. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP, Qinglong Group has witnessed how digital mold technology transforms imaginative design concepts into architectural reality with millimeter-level precision.

Digital Breakthrough of Double-Curved GRC Shapes: A Technological Revolution from Drawing to Reality

Traditional GRC component production relies on manual mold making, and when faced with complex shapes such as double-curved surfaces and hollowed-out textures, it often falls into the predicament of insufficient precision and out-of-control costs. Through the deep integration of parametric design (Rhino+Grasshopper), BIM collaboration, and CNC machining, digital mold technology has established a closed-loop system of "design-simulation-manufacturing." Taking a double-curved curtain wall project of a grand theater as an example, Qinglong's technical team generated a point cloud model through 3D scanning, converting the designer's fluid curves into machinable digital models, keeping mold errors within ±0.5mm—a 300% efficiency improvement over traditional processes.

Core Technical Principles: The Symphonic Resonance of GRC Materials and Digital Molds

The core of this technology lies in the precise match between material properties and digital processes. The high fluidity and fiber-reinforcement characteristics of GRC materials (glass fiber reinforced concrete) provide the physical foundation for complex shapes, while digital molds, with their modular assembly and reusability, solve the pain points of traditional wooden molds that are prone to deformation and high cost. Qinglong's independently developed mold library system has accumulated over 2,000 double-curved shape parameters, capable of rapidly responding to diverse demands from single-curved to double-curved variable curvature, demonstrating unique advantages especially in scenarios such as irregular envelopes of commercial complexes and museum art walls.

Practical Applications: Aesthetic Realization from Landmark Buildings to Cultural Spaces

In the Dongguan Women and Children's Activity Center project, Qinglong applied digital mold technology to achieve seamless splicing of 3,000㎡ double-curved GRC curtain walls, and its gradient texture effect won the Silver Award of the AALBORG WHITE Cup GRC Innovation Award. More notably, this technology reduced the project's overall cost by 18% and shortened the construction period by 25%, confirming the positive cycle of "technological innovation-cost optimization-aesthetic enhancement." Currently, Qinglong's digital mold technology has been widely applied in the real estate, municipal, and cultural venue sectors—from the double-curved sunshades of a commercial complex in Guangzhou to the hollowed-out relief walls of the Nanjing Art Center—continuously expanding the application boundaries of GRC materials.

Industry Value: Defining a New Benchmark for GRC Manufacturing

As a contributing author of the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC), Qinglong feeds its digital mold technology experience back into industry standard development. By establishing a "digital twin" production model and achieving full-process visualized management from design to construction, it not only solves designers' pain point of "difficulty in realizing creative ideas" but also provides developers with a solution for "achieving high premiums at low cost." This ability to deeply integrate material properties, digital technology, and engineering experience is precisely Qinglong's core competitiveness as a national-level high-tech enterprise.

When buildings are no longer constrained by straight lines, digital mold technology is turning GRC materials into "liquid stone" for sculpting space. With 28 years of industry accumulation as its foundation, Qinglong Group interprets its mission of "creating beautiful architecture" through technological innovation, continuously empowering designers and shaping more flowing artistic landmarks for cities on the specialized UHPC/GRC/GRG/GRP track.
