What Equipment Embodies GRC Manufacturers' Automated Production Lines? Core Equipment Analysis and Application Scenarios

Amid the wave of industrialized production of architectural decoration materials, automated production lines have become a key indicator of a GRC manufacturer's core competitiveness. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group has built a digital production system covering everything from design to delivery by integrating intelligent production equipment with full-chain service capabilities, providing customized solutions that combine artistic texture and engineering quality for high-end construction projects.

Core Equipment Matrix of the GRC Automated Production Line: An Intelligent Manufacturing Closed Loop from Raw Materials to Finished Products

Automated production of GRC materials relies on the coordinated operation of key equipment. The production line deployed by Qinglong at its production base in Nanning, Guangxi achieves intelligent management and control of the entire process—from raw material proportioning to forming and curing—through five core equipment systems. The first is the intelligent batching system, which uses PLC-controlled fully automatic metering equipment to mix cement, glass fiber, additives and other raw materials in precise proportions, with errors controlled within ±1%, ensuring the performance stability of each batch of GRC mix. Compared with traditional manual batching, this system reduces the standard deviation of material strength by 40%, laying a solid foundation for subsequent forming.

In the forming stage, the CNC spray forming machine is the "heart" equipment of GRC production. The German-imported spray unit introduced by Qinglong uses high-pressure spray guns to uniformly mix glass fiber with cement mortar and spray it onto the mold surface, working with a six-axis robotic arm to achieve one-step forming of complex curved components. Taking the translucent concrete components in the East Nanjing Road Century Plaza renovation project as an example, this equipment successfully completed hyperbolic shapes with a minimum radius of curvature of 300mm, achieving surface flatness at the industry's high standard of 2mm/2m, with production efficiency more than 3 times higher than manual casting.

For the production needs of large GRC components, the automated compression molding line demonstrates powerful advantages. Qinglong's independently developed hydraulic compression molding equipment, with a programmable pressure control system (adjustable from 0-500 tons), enables mass production of standardized components such as exterior wall cladding panels and sunshades. In the Dongguan Women and Children's Activity Center project, this line produced 200 meters of GRC decorative profiles per day, with product flexural strength stably above 20MPa, far exceeding the requirements of the JGJ/T423-2018 standard.

In the curing stage, the intelligent steam curing kiln solves the pain point of traditional natural curing being heavily affected by environmental conditions. Through precise control of temperature (20-60°C), humidity (85%-95%), and curing cycles, Qinglong has increased the early strength of GRC components by 50% and shortened the curing period from 7 days to 3 days. Combined with the robotic palletizing system, automated transfer and warehouse management of finished components is achieved, improving logistics efficiency by 60% and significantly reducing labor costs and product damage rates.

Application Scenarios Empowered by Equipment: Diverse Applications from Landmark Buildings to Custom Decoration

The technical advantages of automated production equipment enable Qinglong's GRC products to demonstrate outstanding performance in various scenarios. In a commercial complex project in Guangzhou, the openwork relief GRC exterior wall panels produced by the CNC spray forming machine achieved seamless splicing of an 8,000㎡ curtain wall through parametric design, with surface faux stone texture realism reaching 95%, while weighing only 1/4 of natural stone, significantly reducing the building load. The project took only 45 days from detailed design to delivery, setting the fastest record for similar projects.

In the field of municipal landscape, GRC benches, planters and other components manufactured by the automated compression molding line achieve mass production through standardized molds while retaining artistic details with handcrafted texture. In a coastal park project in Shenzhen, the 1,200 GRC landscape components supplied by Qinglong showed no cracking after 5 years of use in an extreme temperature range of -15°C to 60°C, and their weather resistance passed 1,000 freeze-thaw cycle tests, confirming the reliable quality assurance of automated production.

As a national high-tech enterprise, Qinglong Group will continue its mission of "creating beautiful architecture," promoting the industrialization of new decorative materials such as GRC through equipment upgrades and technological innovation. Whether it is the complex curved ceilings of grand theaters or the special-shaped exterior walls of commercial buildings, the automated production lines of Qinglong's GRC factory, with the craftsmanship of "meticulous attention to detail and constant pursuit of excellence," are injecting new momentum into the high-quality development of the architectural decoration industry. In the future, with the deep integration of BIM technology and intelligent manufacturing, Qinglong will further achieve the leap from "manufacturing" to "intelligent manufacturing," providing global customers with more valuable material solutions.
