What Are the Production Processes of GRC Manufacturers? A Comprehensive Analysis of the GRC Manufacturing Process and Technical Features

The GRC production process is a key factor determining product performance and quality. With technological advances, various distinctive production processes have been developed. Mainstream processes include the spray process, premix process, and mesh-laying process, each suited to different product types and production conditions. Understanding the characteristics of these processes helps in selecting the most suitable production solution.

The spray process is a traditional method of GRC production, in which fibers and slurry are sprayed simultaneously onto molds using specialized spraying equipment. This method offers controllable fiber orientation and high product strength, making it suitable for producing complex-shaped components. Qinglong Group has improved spray process parameters, controlling fiber content at 4-5% and achieving flexural strength above 20MPa. Surface quality is controlled through fine operation, reducing air bubbles and defects to enhance aesthetics. The spray process requires skilled technicians and involves higher labor costs, making it suitable for high-end custom products.

The premix process involves pre-mixing fibers with slurry before casting into shape. It offers high production efficiency and is suitable for large-scale standardized production. Uniformity of fiber distribution is difficult to control, and fiber length generally does not exceed 12mm, which affects the reinforcement effect. Through formulation optimization and process adjustments, Qinglong Group has brought premix product performance close to spray-process levels. Good flowability makes it suitable for thin-walled components, and its uniform, consistent surface quality makes it suitable for producing panel products.

The mesh-laying process first places fiber mesh in the mold and then casts the slurry, combining the advantages of the spray and premix processes. The fiber mesh provides uniform reinforcement and stable mechanical properties, making it suitable for flat plate components. Qinglong Group has developed new mesh structures to improve fiber utilization efficiency. It offers high production efficiency, low labor intensity, and competitive costs, making it suitable for large-volume orders.

Hybrid processes combine the advantages of different processes to meet special requirements. For example, the spray process is used for the surface layer to ensure aesthetics, while the premix process is used for the structural layer to control costs. Qinglong Group designs process combinations based on the load-bearing characteristics of components to optimize the performance-cost ratio. Special processes such as vacuum dewatering improve density, and high-pressure molding improves strength, suitable for high-performance applications.

Process selection requires comprehensive consideration of multiple factors. Product shape and size determine process feasibility, and complex curved surfaces are suited to the spray process. Qinglong Group provides process consulting to help customers choose the best solution. Through process innovation and parameter optimization, product performance and production efficiency are continuously improved, driving industry development.
