What are the dimensional deviation control standards for UHPC components?

Dimensional deviation control of UHPC components is a key indicator of a manufacturer's technical capability. In accordance with industry standards and its internal control requirements, Qinglong Group classifies dimensional deviations into four categories: length deviation (±2mm), flatness deviation (≤3mm/2m), thickness deviation (±1.5mm), and angle deviation (≤1°), ensuring precision through whole-process control.

Mold precision is the foundation of control. Mold dimensional deviation is ≤±0.5mm, with surface roughness of Ra≤3.2μm. Qinglong Group uses CNC machining centers to produce molds and conducts regular inspection and maintenance. In the Shenzhen Yirui Biotechnology Building project, the molds maintained precision within ±1mm even after 200 uses, ensuring product consistency.

Production processes affect dimensional stability. Mix proportion design keeps water-binder ratio fluctuation within ≤±0.02 to reduce shrinkage. The curing regime balances heating and cooling to prevent deformation. Through statistical process control, Qinglong Group keeps the dimensional dispersion coefficient within 3%. An online inspection system provides real-time monitoring to promptly identify deviations.

Inspection methods guarantee final precision. 3D laser scanning replaces traditional measurement, improving efficiency fivefold. Qinglong Group creates a digital archive for each panel, making dimensional data fully traceable. This refined dimensional control lays the foundation for perfect installation.
