Precise Positioning Technology for Embedded Parts of Double-Curved GRC Panels: Qinglong GRC Precision Embedded System

The positioning of embedded parts for double-curved GRC panels adopts triple control of "mold datum + digital measurement + adjustable system". Positioning error ≤±2mm, angular deviation ≤0.5°, and gap between embedded parts and the curved surface ≤1mm. Through CNC mold machining (precision ±0.1mm), laser tracker measurement (precision ±0.5mm), and 3D adjustable positioning frames (adjustment range ±10mm), precise positioning of embedded parts is ensured.

Positioning process: datum hole system set on the mold (spacing 500mm); embedded parts with adjustment threads (fine adjustment ±3mm); 100% inspection before casting (pass rate 100%); final inspection records after curing. In a curved curtain wall project, all 2560 embedded parts were precisely positioned, with a first-time installation success rate of 99.8%. Qinglong GRC's precision embedding technology lays the foundation for complex curved surface installation.
