What Are the Production Processes of GRC Manufacturers? — Process Flow and Technical Key Points Explained

The production process of GRC manufacturers covers four major stages: batching, forming, curing, and machining, and the technical essentials of each stage directly affect product quality. Based on 28 years of process experience, Qinglong Group has developed a core process system of precise batching, uniform spraying, scientific curing, and fine machining, ensuring that product strength, durability, and aesthetics reach industry-leading levels.

The batching process is the foundation of quality. Raw materials are precisely weighed, and the water-binder ratio is strictly controlled. Qinglong Group uses an automated system with an error of ≤±0.5% to ensure accurate mix proportions. Fibers are added uniformly to avoid clumping. Ordinary manufacturers may rely on manual operations, resulting in large fluctuations. High-quality processes ensure consistency from the source and stable performance.

The forming process determines product shape. Robotic spraying ensures uniform fiber distribution and high density. In its Hainan project, Qinglong Group adopted vacuum dewatering, reducing porosity to below 5%. The curing process is critical, with temperature and humidity control promoting strength development. Scientific processes enhance product performance and extend service life.

The machining process completes the final treatment. Cutting, drilling, surface treatment, and more ensure smooth installation. Qinglong Group has introduced CNC equipment with high precision and efficiency. Continuous process innovation is constantly optimized to provide customers with better products.
