What Are the Production Processes of GRC Manufacturers? Full-Process Types and Technical Advantages Explained

The core production processes of GRC manufacturers cover five major stages: "mold making, material mixing, casting and forming, curing, and surface treatment." Different processes suit different product types. Through process upgrades and innovation, Qinglong achieves precise realization of complex shapes and consistent product quality.

1. Core Production Processes: Full-Process Analysis

The five processes are closely interconnected. Mold making: steel molds (reusable) for standard products, polyurethane molds/fiberglass molds for customized products; Qinglong's digital molds achieve a precision of ±0.3mm, with shape fidelity of double-curved molds reaching 98%. Material mixing: cement, quartz sand, alkali-resistant fiber, and water are mixed in precise proportions for 3-5 minutes; Qinglong's automated mixing equipment ensures uniform fiber dispersion without agglomeration. Casting and forming: mechanical casting for flat panel products, manual work + high-pressure vibration for double-curved/special-shaped products; Qinglong's post-casting vibration pressure is ≥0.6MPa, with density ≥2.0g/cm³. Curing: constant-temperature (20±2℃) moist curing for 7 days; Qinglong's curing rooms ensure a stable curing environment, with a 100% product strength compliance rate. Surface treatment: grinding, repair, and coloring, with texture treatment for stone-imitation products; Qinglong's stone-imitation products achieve a fidelity of ≥95% and a surface roughness of Ra≤1.6μm.

2. Distinctive Processes and Technological Innovation

Three innovative processes enhance competitiveness. Double-curve forming process: adopting "digital modeling + segmented casting + laser calibration" to achieve a minimum curvature radius of ≤300mm; Qinglong's double-curved panels for the Guangxi New Media Center all use this process. Openwork carving process: five-axis engraving machine + manual fine finishing, achieving an openwork rate of over 50%; the colored openwork carved panels for the Nanning Liyuan Hotel use this process. Composite forming process: combined with thermal insulation and waterproofing materials to achieve functional integration; the roof GRC at the Hainan International Convention and Exhibition Center integrates waterproofing and insulation functions, reducing overall costs by 30%.

3. Qinglong's Process Advantages and Project Practice

Mature processes ensure project quality. Process standardization: formulating the "GRC Production Process Regulations" with quantified key parameters; Qinglong's process qualification rate is 100%. Technology integration: BIM technology + 3D scanning to optimize processes in advance and avoid later rectification; the Shanghai Qingpu R&D project used BIM simulation, with process optimization saving 10% in costs. Project verification: the 15mm-thick carved GRC panels at the Wuhan Han Show Theatre set a new industry record for process complexity; the GRC curtain wall panels for the Sichuan Panzhihua Third-Front Construction Project achieved over 95% fidelity in chiseled stone surface effects. Advanced processes are the core of product quality. With 28 years of accumulated process expertise, Qinglong can meet the needs of various products including flat panels, double-curved, special-shaped, and openwork pieces, providing unlimited possibilities for bringing designers' creative ideas to life.
