What Are the Fabrication Differences Between Single-Curved and Double-Curved GRC Panels? Analysis of GRC Curved Surface Fabrication Technology

The machining differences between single-curved and double-curved GRC panels are mainly reflected in three aspects: mold making, forming process, and curing requirements. Single-curved panel molds can be machined with three-axis machine tools, with precision ≤1mm/2m; double-curved panels require five-axis machine tools, with precision ≤0.5mm/2m. During forming, single-curved panels can be mechanically vibrated, while double-curved panels require manual assistance. During the curing stage, double-curved panels require special supports to prevent deformation.

Machining cost comparison: the mold cost of double-curved panels is 1.5-2 times that of single-curved panels, production hours are 30% higher, and the yield rate is 5% lower. For the double-curved GRC panels of an art center, precise molds and hand finishing achieved the smooth curves required by the design, with errors controlled within ±2mm.

Mold Making Differences

Single-curved panels use three-axis machining; double-curved panels use five-axis machining; these differences affect precision.

Forming Process Differences

Single-curved panels use mechanical vibration; double-curved panels require manual assistance; these differences affect efficiency.

Curing Requirement Differences

Double-curved panels require special supports; these differences prevent deformation.

Cost Difference Analysis

Double-curved panel costs are 50%-100% higher; this analysis guides selection.
