Paths to Improving Production Efficiency of Double-Curved GRC Panels: Technological Innovation and Management Optimization

The production efficiency of double-curved GRC panels directly affects project schedules and overall costs. As double-curved GRC panels are increasingly used in high-end architecture, how to improve production efficiency while ensuring product quality has become a core concern of the industry. This requires efforts across multiple dimensions—including technological innovation, process optimization, and management upgrades—to achieve dual improvements in production efficiency and product quality.

The complex curved surfaces of double-curved GRC panels make their production process more complicated than that of flat GRC panels, placing higher demands on production technology and management. As an enterprise with a GRC production capacity of 600,000 square meters, Qinglong has, through a series of innovative measures in long-term project practice, significantly improved the production efficiency of double-curved GRC panels and successfully ensured the on-time delivery of multiple large-scale projects.

Mold Technology Innovation: The Core Support for Double-Curved GRC Panel Production Efficiency

Modular molds and standardized design are key to improving efficiency. Qinglong adopts modular fiberglass molds, designing universal modules for different double-curve parameters and quickly assembling dedicated molds through module combinations to reduce mold fabrication cycles. Meanwhile, a mold library has been established to uniformly manage and reuse molds for common double-curved shapes, raising the mold turnover rate to more than 50 uses. In addition, 3D printing technology has been introduced to produce master molds, shortening mold fabrication cycles by more than 30%, which is particularly suitable for rapid prototyping and small-batch production of complex double-curved shapes. In the Shanghai Astronomy Museum public art project, the application of 3D-printed mold technology greatly improved the production efficiency of double-curved GRC sculptures.

Production Process Optimization: Streamlining Workflows and Increasing Automation

The introduction of automated production equipment is at the core of process optimization. Qinglong uses an automated slurry mixing system that precisely controls mix proportions and mixing time, increasing production efficiency by more than 2 times while delivering more stable slurry quality. For the laying of fiberglass mesh on double-curved GRC panels, semi-automatic mesh-laying equipment combined with curved-surface positioning technology is used to ensure precise and efficient fiberglass mesh placement and reduce manual operation errors. In addition, the curing process has been optimized by combining steam curing with natural curing, shortening the curing cycle of double-curved GRC panels from 7 days to 3 days and greatly improving production turnover. In the Hainan International Convention and Exhibition Center project, this optimized process successfully achieved rapid batch production of double-curved GRC panels.

Production Management Upgrade: Refined Control and Coordinated Operations

Refined management is an important guarantee for improving efficiency. Qinglong has established a full-process digital management system that tracks the design, production, inspection, and other stages of double-curved GRC panels in real time, optimizing production plans and reducing waiting time. Adopting a "zoned operations, assembly-line production" model, the production process is divided into multiple stages, including mold preparation, slurry pouring, fiberglass laying, and curing and demolding, with clear time milestones and quality requirements for each stage to achieve coordinated and efficient operations. Meanwhile, employee skills training is strengthened to cultivate versatile production personnel and improve the operational efficiency and quality control of individual processes. Through these management measures, the unit production efficiency of Qinglong's double-curved GRC panels has increased by more than 40%.

The improvement in double-curved GRC panel production efficiency is the result of collaborative innovation in technology, processes, and management. With 28 years of industry experience, Qinglong continues to explore optimization paths and has achieved continuous improvements in production efficiency while ensuring product quality. As a national high-tech enterprise, Qinglong has always been innovation-driven, leading the development of double-curved GRC panel production technology, providing customers with efficient, high-quality products and services, and helping projects advance rapidly.
