What Are the Production Processes of GRC Manufacturers? A Complete Analysis of Qinglong GRC Process Technology

GRC production processes directly affect product performance and appearance quality. Through 28 years of technical accumulation, Qinglong has developed multiple mature processes including spray-up, premix, and mesh laying, and can select the optimal solution based on product requirements.

In the "Guancao" woven texture project at the Dongguan Women and Children's Activity Center, Qinglong innovatively combined the spray-up process with engraving technology to perfectly reproduce the delicate texture of traditional Guancao grass. The project first produced high-precision molds using CNC engraving machines, then applied an improved spray-up process to ensure directional fiber distribution in the surface layer, and finally enhanced the details through hand finishing. This process combination achieved over 95% fidelity in the finished product and received high praise from designers. The process used in the project has now been submitted for a national patent.

Spray-up Process Advantages

Uniform fiber distribution and high strength. Suitable for complex shapes and capable of achieving rich surface effects. The process is technically demanding, requiring specialized equipment and expertise.

Premix Process Characteristics

High production efficiency, suitable for standard products. Fiber length is limited and strength is slightly lower. Lower cost, suitable for large-volume production.

Special Process Innovations

Light-transmitting GRC requires special mix ratios and processes. Stone-simulating effects require multi-layer spray technology. These special processes reflect a manufacturer's technical strength.

Process selection requires professional judgment. It is recommended to communicate in depth with the manufacturer's technical team to determine the best process solution.
