Principles and Application Analysis of Digital Mold Technology for Double-Curved GRC Forms

When architectural aesthetics collide with digital technology, double-curved GRC forms are using digital mold technology as their brush to outline the limitless possibilities of future architecture.

In the field of contemporary architectural decoration, GRC (Glass Fiber Reinforced Concrete) has become an ideal material for shaping complex architectural forms thanks to its lightweight, high-strength, and flexible shaping characteristics. In particular, double-curved GRC components, with their smooth curved lines and unique spatial expressiveness, are widely used in high-end buildings such as grand theaters, museums, and commercial complexes. However, traditional mold-making processes have long faced challenges in the precision, production efficiency, and cost control of double-curved shapes. As an industry-leading enterprise with 28 years of experience in deepened design and production of UHPC/GRC/GRG/GRP materials, Qinglong Group has successfully solved this challenge through the innovative application of digital mold technology, providing technical support for the large-scale application of double-curved GRC.

Double-Curved GRC Digital Mold Technology: A Full-Process Innovation from Design to Manufacturing

The core difficulty of double-curved GRC forms lies in the complexity of curved surfaces and precision control. Traditional wooden or steel molds not only involve long production cycles and high costs, but also struggle to meet the replication requirements of complex curved surfaces. Digital mold technology achieves the precise transformation from virtual models to physical molds through the deep integration of parametric design, 3D scanning, and CNC machining. Leveraging the technical advantages of its provincial-level R&D center, Qinglong Group combines BIM technology with parametric design tools such as Rhino and Grasshopper to quickly generate digital models of double-curved surfaces, and uses algorithms to optimize mold segmentation schemes, reducing material waste. In the production stage, large CNC engraving machines perform high-precision machining on mold base materials (such as high-density foam and resin panels), ensuring that mold surface errors are controlled within ±0.5mm and perfectly reproducing the design intent.

Technical Principles and Core Advantages: Redefining the Production Paradigm of Double-Curved GRC

The core of digital mold technology lies in "digitally driven manufacturing." Its technical principles can be summarized in three stages: first, parametric modeling based on architectural design drawings, constructing precise 3D models through the digital definition of key parameters such as surface curvature and arc; second, digital machining of molds, using CAM (Computer-Aided Manufacturing) technology to convert digital models into machining instructions that drive CNC equipment to complete automated mold engraving; third, modular reuse of molds, achieving rapid adaptation to different double-curved shapes through parametric adjustment of standard modules. Compared with traditional processes, this technology offers three major advantages: first, improved precision, with surface forming errors reduced from the traditional ±3mm to within ±1mm; second, increased efficiency, with mold production cycles shortened by more than 50%; third, optimized costs, with modular design reducing mold consumables by 30%, making it especially suitable for multi-batch, small-batch customized projects.

Engineering Applications and Industry Value: Practical Achievements of Qinglong's Digital Technology

Qinglong Group has successfully applied double-curved GRC digital mold technology to multiple landmark projects. For example, in the double-curved exterior wall system of a grand theater in a provincial capital city, digital molds enabled the precise assembly of more than 1,200 special-shaped GRC components, with surface smoothness matching the design drawings at 99%. In another commercial complex project, the technology helped complete an 18-meter-diameter double-curved atrium ceiling, with mold making and component production finished in just 28 days, saving 40% of the construction period compared with traditional processes. These cases confirm the significant value of digital mold technology in improving the engineering quality of double-curved GRC and shortening construction periods. As a national high-tech enterprise and a participant in formulating GRC industry standards, Qinglong Group has not only provided customers with full-chain services from deepened design to after-sales maintenance through technological innovation, but has also driven the industry's transformation from "experience-driven" to "digitally driven."

In the field of architectural decoration materials manufacturing, technological innovation is the core driving force for the sustainable development of enterprises. Building on 28 years of industry experience, Qinglong Group has not only solved the production challenges of complex shapes through the R&D and application of double-curved GRC digital mold technology, but has also fulfilled its corporate mission of "creating aesthetically beautiful architecture." In the future, with the deep integration of technologies such as BIM and AI, digital mold technology will further expand the application boundaries of materials such as GRC/GRG/UHPC, opening up new paths for the integration of architectural aesthetics and engineering practice. As a leader in the field of new decorative building materials, Qinglong Group will continue to focus on innovative breakthroughs in material technology, providing designers and owners with more professional and efficient solutions, and driving the industry toward green and intelligent development.
