Acrylic Bending Tips for Light Boxes and Illuminated Letters

Light boxes and illuminated letters need clean visible surfaces and consistent curves. Use a heating width that matches the radius, protect cosmetic faces and verify the fit with the frame or LED structure. Why it matters A sharp line is not suitable for every illuminated design. Wider arcs can reduce whitening and create smoother light transitions. Long parts also need full-length support to prevent waves. Practical checklist Test with the same color and sheet grade used in production. Use a radius template for repeated letters or corners. Check clearance for LEDs, wiring and assembly hardware. Which machine fits? Both models support straight and 10-70 mm arc work. The Factory Bender's longer 1.6 m stroke benefits medium-large components. Frequently asked question Does clear acrylic need different care from opaque sheet?
