What Are the Key Steps in the Factory Prefabrication Stage of UHPC Curtain Wall Panel Production? Process Flow and Qinglong Group's Smart Manufacturing

The factory precasting stage of UHPC curtain wall panels comprises six key steps: "digital design – raw material proportioning – mold preparation – casting and forming – curing and hardening – inspection and packaging," with precise control required throughout the entire process. Qinglong Group has introduced a fully automated production line from Germany, employing advanced processes such as BIM modeling (error ≤0.1mm), automatic batching (precision ±0.5%), robotic casting (fiber distribution uniformity ≥95%), and intelligent curing (temperature control ±2°C), shortening the production cycle to 3–5 days with a product pass rate stably above 99.5%. In the 120,000 m² roof panel project at the Hainan International Convention and Exhibition Center, standardized precasting improved installation efficiency by 50% and kept errors within ±2mm. Factory precasting is the optimal model for balancing quality, efficiency, and cost.

Digital Design Is the Starting Point

Rhino+Grasshopper parametric design is adopted to automatically generate machining data. Qinglong Group's BIM center has tripled design efficiency. Models go directly to CNC machines for seamless connection.

Production Control Is the Core of Quality

The batching system weighs materials with precision, keeping the water-cement ratio at 0.20–0.22; vacuum dewatering expels air bubbles; steam curing promotes strength development. Qinglong Group's MES system monitors in real time to ensure every step meets standards.

Inspection and Packaging Safeguard Factory Quality

Each panel undergoes inspection for dimensions, strength, and appearance; custom packaging prevents transport damage. Qinglong Group's standardized processes deliver reliable products to customers. Intelligent manufacturing is the future of the industry.
