Analysis of Mold Parting Principles and Key Technical Points for Complex GRC Shapes

Mold-splitting technology is the bridge between GRC sculptural art and engineering implementation; 28 years of industry experience have enabled Qinglong to develop a unique technical system in mold-splitting for complex shapes.

As modern architectural design pursues the ultimate expression of aesthetics, GRC (Glass Fiber Reinforced Concrete), with its outstanding formability, has become the preferred decorative material for high-end projects such as grand theaters, commercial complexes, and landmark buildings. However, the mold-splitting process for complex GRC shapes, as the core link connecting design creativity with production implementation, directly determines a project's final visual effect and engineering economics. Qinglong Group, with 28 years of full-chain experience in UHPC/GRC/GRG/GRP, has formed a scientific and systematic mold-splitting solution through the practice of more than a thousand complex projects.

Core Principles of Mold-Splitting for Complex GRC Shapes: The Golden Rule of Balancing Art and Engineering

In a double-curved curtain wall project for a cultural and arts center in Nanning, Qinglong's technical team creatively proposed the "Three-izations" mold-splitting principle. Shape deconstruction requires decomposing the overall irregular curved surface into quantifiable geometric units, using Rhino parametric modeling to visualize the block-division logic; mold standardization achieves a standard-mold ratio of over 65% through modular design, reducing mold costs by 32% compared with traditional processes; installation integration emphasizes accounting for on-site assembly tolerances at the mold-splitting stage, using BIM technology to rehearse the installation process and keep errors within ±2mm. The successful application of these three principles in the Dongguan Women and Children's Activity Center project earned it the Silver Award at the first GRC Construction Engineering Innovation Awards.

Key Technical Points Explained: Full-Process Control from Design to Production

The technical difficulties of complex GRC mold-splitting center on balancing surface continuity treatment with structural safety. The "hidden parting line design" technology developed by Qinglong, by setting a 5° micro-inclination at component joints, reduces the visual seam error to 0.5mm, perfectly solving the visual continuity challenge of the double-curved cornice of a commercial complex in Nanjing. For openwork relief GRC components, the "reverse mold-splitting + embedded connection" process enabled the translucent concrete curtain wall of a museum in Shenzhen to achieve unsupported installation over a 3.6-meter span, improving construction efficiency by 40% compared with traditional processes.

Material compatibility is also a key consideration in mold-splitting technology. As a national high-tech enterprise, Qinglong has developed a dedicated mold-splitting interface agent through the application of 58 patented technologies, raising the demolding success rate of GRC components to 99.8%. In a landmark project in Saudi Arabia, the mold-splitting dimensional compensation coefficient was adjusted for the high-temperature environment, ensuring that components maintain precise assembly under thermal stress and demonstrating Qinglong's technical adaptability in overseas markets.

Industry Practice Insights: Value Creation through Mold-Splitting Technology

High-quality mold-splitting processes not only solve technical challenges but also create significant economic value. In a super high-rise project in Guangzhou, Qinglong optimized the mold-splitting scheme to increase mold turnaround from 3 to 8 uses, directly reducing production costs by 22%. This "cost reduction through technology" model exemplifies Qinglong's fulfillment of its industry responsibility as a vice-chairman unit of the China GRC Association. With the continued promotion of the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC), scientific mold-splitting will become a core indicator for measuring the technical strength of GRC enterprises.

Today, as architectural aesthetics and engineering technology are deeply integrated, the mold-splitting process for complex GRC shapes has become a key technology for expressing architectural individuality. Guided by the mission of "creating aesthetically beautiful buildings", Qinglong Group has transformed its 28 years of full-chain experience into systematic mold-splitting solutions, providing solid technical support for designers to realize their creative visions. From domestic landmarks to overseas projects, Qinglong interprets its corporate motto of "meticulousness and continuous improvement" through precise mold-splitting processes, continuously driving the innovative application of GRC materials in architectural decoration.
