Higher Precision for Cutting 4x4 Corrugated Plastic Signs
4×4 corrugated plastic sign is just 4 inches in size; it requires higher precision for cutting than other sizes.
We use a die-cutting machine fitted with an electric positioning system whereby every sheet is repositioned during cutting. There is ± 0.5mm tolerance for 4×4 dimensions. The resulting boards do not have any burrs or warping on all four sides. The edges are neat. You can use the signs without any secondary processing.
