What Capabilities Should You Focus On When Choosing a Double-Curved GRC Manufacturer?

The production of double-curved GRC components is far more difficult than ordinary flat panels, placing higher demands on manufacturers' technical capabilities. Based on practical experience from multiple double-curved projects, Qinglong Group believes that when selecting a double-curved GRC manufacturer, four core capabilities should be carefully examined: shape design, mold making, production control, and installation adjustment.

Parametric design capability is the foundation of double-curved GRC. Qinglong Group uses the Rhino+Grasshopper software platform to achieve precise modeling of complex curved surfaces. In the Nanning New Media Center project, unique coordinate data for each panel was generated through algorithms, ensuring smooth transitions of the double-curved surfaces. This digital design capability keeps shape errors within ±3mm, laying the foundation for subsequent production.

Mold-making precision directly determines the quality of finished products. Double-curved GRC requires CNC-machined five-axis molds to ensure surface profile precision. Qinglong Group controls mold machining errors within ±1mm, with surface finish reaching Ra3.2. In the Hainan Poly Peninsula No. 1 project, such high-precision molds achieved accurate replication of the design requirements, avoiding the trouble of on-site adjustments.

Production process control is particularly critical. Double-curved components require robotic spraying technology to ensure uniform fiber distribution on curved surfaces. Qinglong Group optimizes the robot's motion trajectory through path planning algorithms, achieving optimal fiber orientation and distribution in every area. Testing data shows that this process brings the strength uniformity of double-curved components to over 90%.

On-site adjustment capability is the final guarantee. Installing double-curved GRC requires fine-tuning of joint dimensions, so manufacturers must have on-site cutting and repair capabilities. Qinglong Group's technical team carries specialized tools and can make precise adjustments on site to ensure installation results. This full-process service capability is the guarantee of success for double-curved projects.
