What Are the Steps in the Production Process of UHPC Exterior Wall Decorative Lines?

The production process of UHPC exterior wall decorative lines can be distilled into a seven-step workflow: "detailed design, mold making, batching and mixing, casting and forming, curing and demolding, surface treatment, and quality inspection." Each step directly affects the precision and aesthetics of the finished product. In the European-style lines project for Wuxiang China Resources MixC One in Nanning, Qinglong Group applied full-process control: optimized segmentation based on BIM models (to avoid stress concentration), CNC-carved high-precision molds (tolerance ≤0.1mm), automatic batching plant (precision ±0.5%), robotic spray forming (fiber uniformity ≥95%), steam curing (80℃×24h), manual polishing or sandblasting, and full 3D scanning inspection. This process ensures that tens of thousands of meters of lines achieve dimensional tolerances of ≤±1.5mm, realizing perfect joints. The production process is a fusion of art and technology.

Detailed Design and Mold Making Are the Starting Point

Structural optimization is carried out based on architectural drawings to determine joint positions and embedded part locations. Molds are made of steel or resin, with CNC machining ensuring smooth profile surfaces. Qinglong Group's mold library stores hundreds of line profiles for quick retrieval.

Production and Forming Determine Intrinsic Quality

Materials are fed strictly according to the mix proportions and mixed until uniform. Spray or casting methods are used for forming, with vibration assistance to compact complex lines. Qinglong Group's production lines maintain constant temperature and humidity to ensure consistent workability.

Curing and Surface Treatment Enhance Value

Steam curing promotes strength development, and imperfections are repaired after demolding. Surfaces can be polished, bush-hammered, or colored to achieve different effects. For a project in Hainan, we used stone-effect coatings to blend the UHPC lines seamlessly with the stone curtain wall.

Inspection and Packaging Ensure Factory Quality

Each product undergoes dimensional measurement, visual inspection, and sampled strength testing. After passing, products are labeled and packaged to prevent bumps and scratches. Qinglong Group controls its factory pass rate at above 99%.

Refined craftsmanship is the guarantee of beautiful and durable UHPC lines. Qinglong Group standardizes and digitizes every step to provide customers with high-quality decorative components.
