What Are the Mold Precision Requirements for Making UHPC Double-Curved Panels? Qinglong UHPC Double-Curved Panel Mold Technical Standards

UHPC double-curved panel molds demand extremely strict precision: working surface profile tolerance ≤0.5mm/2m, positioning datum accuracy ±0.3mm, and opposite-side dimensional deviation ≤1.0mm. Qinglong UHPC machines molds with five-axis CNC machine tools, combined with laser tracker inspection, ensuring double-curved panel forming accuracy of ±1.5mm and fully meeting the appearance requirements of complex curved-surface architecture.

During mold fabrication, Qinglong UHPC implements strict quality control: first, 3D scanning captures the design model data (point cloud accuracy 0.1mm); then a CNC machining center (positioning accuracy ±0.1mm) carves the steel mold; finally, a laser tracker (accuracy ±0.5mm/m) performs 3D inspection. For a double-curved curtain wall project at a cultural and arts center with a maximum curvature radius of 300mm, the molds underwent 72 hours of constant-temperature aging treatment to eliminate internal stress, resulting in a final product surface smoothness error ≤2mm and a perfect double-curved surface effect.

Profile Precision Control Standards

Working surface profile ≤0.5mm/2m; joint seam misalignment ≤0.2mm; these standards ensure panel shape accuracy.

Positioning System Accuracy Requirements

Datum hole position accuracy ±0.3mm; opposite-side dimensional deviation ≤1.0mm; these requirements ensure precise positioning.

Mold Material Selection Standards

Mold steel hardness HRC48-52; hard chrome plating thickness 0.05-0.08mm; these choices ensure mold durability.

Inspection and Acceptance Specifications

CMM inspection of the full profile; laser tracker verification of curved surfaces; these specifications strictly control quality.

Mold precision determines product quality. Qinglong UHPC high-precision molds ensure perfect forming of double-curved panels.
