How to Judge a GRC Manufacturer's Mold Development Capability?

In the field of architectural decoration, GRC (Glass Fiber Reinforced Concrete) has become the ideal choice for high-end projects such as grand theaters, commercial complexes, and landmark buildings thanks to its lightweight, high-strength, and flexible shaping characteristics. As the core link in GRC production, molds directly determine product precision, efficiency, and cost. For real estate developers, architectural designers, and public project leaders, accurately assessing a GRC manufacturer's mold development capability is key to ensuring project quality and schedule. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP, Qinglong Group will analyze the core criteria for evaluating GRC manufacturers' mold development capabilities from three dimensions: technical strength, production experience, and innovation capability.

### I. Mold Design and Detailing Capability: The "Translator" from Drawings to Finished Products

The first step in mold development is converting design drawings into producible physical molds, which requires the manufacturer to have strong detailing design capabilities. A professional GRC manufacturer should have a technical team proficient in parametric design (such as Rhino and Grasshopper), BIM technology, and 3D scanning, capable of handling special shapes such as complex double-curved surfaces, hollow reliefs, and oversized irregular components. For example, in the Nanjing Road Century Square renovation project, Qinglong Group achieved precise mold making for light-transmitting concrete components through the coordination of 3D scanning and BIM, ensuring the minimum radius of curvature was controlled within 300mm and surface treatment precision reached the millimeter level. In addition, the manufacturer must also be able to optimize the mold structure based on material characteristics (such as GRC's shrinkage rate and strength development curve) to avoid problems such as difficult demolding and component deformation.

### II. Mold Manufacturing Processes and Equipment: The "Safety Net" for Precision and Efficiency

The material selection and processing techniques of molds directly affect product quality and production efficiency. High-quality GRC manufacturers typically use high-performance mold materials such as steel molds and fiberglass molds (GRP molds). Steel molds are suitable for large batches of standardized components, while fiberglass molds are better suited to the customized production of complex shapes. Taking Qinglong Group's Guangxi production base as an example, it is equipped with advanced equipment such as CNC machining centers and large hydraulic presses, enabling automated cutting, welding, and polishing of molds and ensuring a mold dimensional error of ≤0.5mm. Meanwhile, the manufacturer must also establish a strict mold quality inspection system, such as precision verification with coordinate measuring machines and testing mold durability under simulated production environments—this is also an important support behind Qinglong's ability to handle an annual production capacity of 600,000 square meters.

### III. Mold Innovation and Cost Control: The "Wisdom Bank" for Balancing Art and Economy

While meeting design effects, mold development capability is also reflected in cost optimization and technological innovation. Experienced GRC manufacturers reduce costs through modular design, reusable mold structures, and other approaches—for example, breaking irregular components down into standard modules and combining them to achieve complex shapes, which improves mold utilization while shortening production cycles. In the Dongguan Women and Children's Activity Center project, Qinglong Group adopted an innovative design of "universal mold frame + interchangeable panels," raising the mold reuse rate by 40% and reducing project costs by 15%. In addition, manufacturers should also focus on the research and development of new mold materials, such as eco-friendly resins and lightweight composite materials, reducing energy consumption while ensuring strength—this aligns closely with Qinglong's philosophy of "professional innovation and environmental protection."

### IV. Project Cases and Industry Certifications: The "Touchstone" of Strength

The most intuitive way to judge a GRC manufacturer's mold development capability is to examine its past project cases and industry qualifications. For example, as a contributing member of the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018), Qinglong Group has completed overseas projects such as the Malaysia airport and Saudi Arabian commercial complexes, as well as supplying GRC components for multiple domestic landmark buildings, with its mold development capability recognized by the International GRC Association and the Huaxia Award of the Ministry of Housing and Urban-Rural Development. Customers should pay close attention to whether the manufacturer holds qualifications such as "National High-Tech Enterprise" and "Specialized, Refined, Distinctive, and Innovative Enterprise," and whether it owns invention patents related to molds (for example, among Qinglong's 58 patents, many involve mold structure optimization).

### Conclusion: Choosing a GRC Manufacturer with Excellent Mold Capability Is Choosing the Cornerstone of Project Success

Mold development capability is a concentrated reflection of a GRC manufacturer's comprehensive strength. It not only determines the artistic expressiveness of products but also affects project cost, schedule, and safety. As an industry leader dedicated to the UHPC/GRC/GRG/GRP field for 28 years, Qinglong Group has always taken "creating aesthetically beautiful architecture" as its mission. Through technological research and development and accumulated experience, it has built a full-chain advantage from mold design to production and installation. Whether it is the cost control needs of real estate developers or the challenge of bringing designers' creativity to life, Qinglong can provide expert-level solutions, joining hands with partners to create architectural masterpieces that stand the test of time.
