What Is the Principle of Digital Mold Technology for Double-Curved GRC Shapes? — Qinglong Group's Digital Twin Mold System

Digital mold technology for double-curved GRC shapes is the key to achieving complex geometries. Qinglong Group combines 3D scanning, parametric design, and CNC machining to control mold precision within ±1mm, perfectly reproducing the design intent.

3D scanning captures precise data. Laser scanners are used to acquire point cloud data of the design model with an accuracy of 0.1mm. In the Wuhan Hanxiu Theater project, Qinglong Group scanned a 1:1 model and generated 20 million data points to ensure shape fidelity. The data is processed through reverse engineering to optimize surface smoothness and avoid machining defects.

Parametric design optimizes mold structure. Algorithms generate rib layouts to ensure mold rigidity. Qinglong Group developed adaptive mesh segmentation technology that divides large curved surfaces into machinable units, with seam errors ≤0.5mm. Epoxy resin is the preferred mold material, with a heat deflection temperature ≥60°C, ensuring precision in repeated use.

CNC machining achieves precise forming. Five-axis machining centers use tool paths optimized through simulation. Qinglong Group's Nanning production base achieves machining precision of ±0.1mm and surface roughness Ra≤3.2μm. This digital mold technology increases the production efficiency of double-curved GRC by 3 times and reduces costs by 20%.
