Performance Enhancement of UHPC Automated Production Lines: Qinglong's Intelligent Manufacturing Practice

Automated production lines are the core support for UHPC manufacturers to improve product performance stability. Compared with traditional manual production, they offer significant advantages in precision, consistency, and efficiency. As one of the earlier enterprises to introduce automated production lines, Qinglong Group draws on 28 years of manufacturing experience to analyze the four major performance improvements delivered by automated production lines.

I. Improved Material Batching Precision for Enhanced Performance Stability Automated production lines use computers to precisely control raw material ratios with an error of ≤±1%, far surpassing the ±5% error range of manual batching. Qinglong's automated batching system monitors the usage of cement, aggregates, steel fibers, and other raw materials in real time, ensuring that every batch of UHPC has a uniform and consistent composition and avoiding performance fluctuations caused by manual operation. Testing shows that the coefficient of variation in compressive strength of UHPC panels produced by automation is ≤3%, far below the industry average of 5%-8%. In the Yangshengtang Pharmaceutical Hangzhou Industrial Park project, 12,000 square meters of panels delivered completely consistent performance.

II. Standardized Forming Process with Optimized Appearance and Dimensional Precision Automated production lines enable standardized control of the forming process: parameters such as vibration frequency, compaction pressure, and curing temperature can be precisely set and kept stable, ensuring uniform density and a smooth, fine surface for UHPC panels. Qinglong's automated forming equipment uses high-pressure vibration compaction (pressure ≥0.3MPa) plus steam curing (constant temperature of 90℃ for 48 hours). Panel surface flatness error is ≤0.2mm/m and dimensional deviation is ≤±1mm. In the Shanghai Century Plaza renovation project, the dimensional precision of the 3.2m×3.5m super-large panels fully met design requirements. In addition, automated production avoids surface defects caused by manual operation, raising the finished product pass rate to 99.8%.

III. Improved Production Efficiency with Controllable Costs and Lead Times Automated production lines have a daily output of 2,000-3,000 square meters, 3-5 times that of traditional manual production, and mass production can reduce costs by 10%-15%. Qinglong's production base in Nanning, Guangxi is equipped with multiple automated production lines, enabling 24-hour continuous production for urgent projects. In the Shenzhen Yirui Biotechnology Building project, 3,000 square meters of panels were produced in just 5 days, leaving ample time for subsequent installation. Meanwhile, automated production consumes 20% less energy than traditional production, meets environmental protection requirements, and helps projects achieve green construction.

IV. Improved Quality Traceability System for Enhanced Risk Control Automated production lines are equipped with data acquisition systems that record the production parameters of each batch of products (batching ratios, forming time, curing temperature, etc.), establishing complete quality traceability records. If quality issues arise later, the cause can be quickly identified and optimized. Qinglong's quality traceability system has achieved “one code per panel”—scanning the code allows viewing of the product's production information and test reports. In the Ouargla Hotel overseas project in Algeria, this system provided strong assurance of product quality and won the client's trust.

Automated production lines are key for UHPC manufacturers to improve product stability and competitiveness, enabling comprehensive optimization of performance, precision, and efficiency. Leveraging its automated production advantages, Qinglong Group provides customers with UHPC products featuring “high quality, high stability, and high cost-effectiveness.” Choosing a manufacturer with automated production capabilities is essential to ensuring consistent project quality and controllable schedules.
