What Is the GRC Production Process? Analysis of 2024 Standardized Processes and Technological Innovation

The GRC production process is the core guarantee of product quality. The standardized procedures and technological innovations of high-quality manufacturers enable precise control from design to finished product. As an industry leader with 28 years of experience, Qinglong GRC has established a fully standardized process covering "design - mold making - production - curing - inspection," while incorporating multiple technological innovations to ensure consistent product quality.

Preliminary Design Development: Precisely Matching Requirements

The first step in production is design development. Based on customer requirements and project drawings, Qinglong's technical team applies BIM technology for parametric design, optimizing component structures and installation joints. For components with complex shapes, such as the hyperbolic GRC panels of the Guangxi New Media Center, 3D modeling is used to simulate production and installation, avoiding clash risks in advance; for conventional components produced in batches, such as Roman columns and decorative moldings, standardized design ensures mold versatility and product consistency. The design development stage also defines key parameters such as raw material ratios and fiber content, providing a precise basis for production. For example, the GRC relief components of Shenzhen Xinghewan achieved precise rendering of pattern details through design development.

Mold Making and Raw Material Preparation: The Foundation of Quality

Molds are key to GRC shaping. Qinglong makes molds according to design drawings: conventional components use steel or GRP molds, which are reusable and reduce costs; components with complex shapes use custom silicone or polyurethane molds to ensure shaping precision. For example, the GRC sculptures of the Shanghai Astronomy Museum used custom molds to achieve complex shapes over 3 meters. Raw material preparation strictly follows mix ratio requirements: cement, quartz sand, alkali-resistant glass fiber, and other materials are weighed proportionally, and admixtures are precisely metered. Qinglong uses an automated batching system with a batching error of ≤±1%, ensuring consistent performance in every batch.

Forming, Curing, and Finished Product Inspection: The Core Process

The forming process uses spray-up or premix forming, and Qinglong selects the appropriate process for different products: thin-walled components use spray-up forming to ensure even fiber distribution; thick-walled components use premix forming to improve density. After forming, components enter standard curing kilns, where Qinglong controls the curing temperature at 20-25°C and humidity at ≥90% for 7-14 days, ensuring steady strength development and preventing early cracking. Finished product inspection is the final checkpoint: Qinglong tests every product for dimensional accuracy, strength, and appearance quality, with dimensional error ≤±2mm, flexural strength ≥12MPa, and no obvious appearance defects; only products that pass inspection may leave the factory. For example, the GRC cladding panels of Guangzhou Dongzhu Shangdu Commercial City undergo strict inspection to ensure installation accuracy meets standards.

The GRC production process is a systematic project. Qinglong GRC, based on standardized procedures, incorporates technological innovations such as BIM design, automated batching, and precision curing; behind an annual capacity of 600,000 square meters lies strict control over every step. Understanding the production process helps customers better evaluate a manufacturer's strength. Only by choosing a manufacturer like Qinglong, with mature craftsmanship and advanced technology, can customers obtain GRC products of reliable quality.
