Analysis of the Equipment in GRC Manufacturers' Automated Production Lines and Their Technical Features

In the architectural decoration materials industry, production efficiency and product precision are important manifestations of a company's core competitiveness. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong has achieved the leap from traditional manufacturing to intelligent manufacturing through comprehensive deployment of automated production lines. This article provides an in-depth analysis of the key equipment and technical features of GRC manufacturers' automated production lines, offering designers and owners an in-depth reference on modern building materials production.

Core Equipment Configuration of GRC Automated Production Lines

The construction of GRC automated production lines revolves around three major goals: precision, intelligence, and efficiency, mainly covering three stages: material preparation, molding and processing, and quality inspection. In the material mixing stage, the fully automatic batching system achieves precise proportioning of raw materials such as glass fiber, cement, and additives through a PLC control system, with errors controlled within ±1%, ensuring the stability of the mechanical properties of GRC materials. In the molding stage, the CNC spray-up machine uses high-pressure air atomization technology to uniformly mix fibers with cement mortar and spray them onto the mold surface, working with robotic arms to achieve one-step forming of complex curved components, with production efficiency over 300% higher than traditional manual methods.

To meet the production needs of large GRC components, Qinglong has introduced a robotic laying system that achieves automated laying of glass fiber mesh through 3D visual positioning technology, solving problems in manual operation such as uneven overlap and residual air bubbles. In the curing stage, the intelligent steam curing kiln uses closed-loop control of dual temperature and humidity parameters to shorten the curing period of GRC components from 7 days under traditional natural curing to 3 days, while increasing compressive strength by 20%. In addition, the automated cutting and grinding equipment is equipped with laser contour scanning to precisely process special-shaped components, controlling dimensional errors within ±0.5mm to meet the precision requirements of high-end buildings.

Technical Features and Industry Value of Automated Production

The technical advantages of Qinglong's GRC automated production lines are first reflected in the deep integration of parametric design and intelligent manufacturing. Through real-time data interaction between BIM technology and production equipment, seamless connection from design models to production instructions can be achieved, supporting mass production of complex shapes such as double-curved surfaces and openwork reliefs. For example, in the Nanjing East Road Century Plaza renovation project, the production of translucent concrete components achieved a precise balance between light transmittance and structural strength through this system, winning the AALBORG WHITE Cup UHPC Construction Engineering Innovation Award.

Secondly, automated production significantly improves material utilization and environmental performance. The precise batching system reduces raw material loss by 15%, and the dust collection device combined with bag filter dust collectors achieves a dust recovery rate of over 95%, in line with national green factory standards. Meanwhile, the AI quality inspection system equipped on the production line uses machine vision to identify surface defects of components in real time, with a detection accuracy of 99.2%, effectively preventing non-conforming products from entering the construction stage.

As a national high-tech enterprise, Qinglong's automated production lines serve not only the domestic market—its GRC components have been exported to overseas markets such as Malaysia and Australia. By integrating full-chain advantages in detailed design, manufacturing, and construction installation, Qinglong, with the mission of "creating beautiful architecture," is promoting the innovative application of UHPC/GRC/GRG/GRP materials in the high-end building sector and setting a benchmark for intelligent manufacturing in the industry. In the future, with the deeper application of Industry 4.0 technologies, automated production lines will further achieve flexible production, meeting the dual needs of personalized customization and large-scale production, and injecting new momentum into the high-quality development of the architectural decoration industry.
