What is the main advantage of extruded acrylic over cast acrylic for signage?

Extruded acrylic offers more consistent thickness tolerances across the sheet and a lower cost per square meter compared to cast acrylic. This makes it ideal for high-volume signage projects like channel letters and LED lightboxes where budget matters and the optical differences between extruded and cast are not critical.

What thickness options are available for Luminao extruded acrylic?

Luminao and Just Extruded Acrylic are available in thicknesses ranging from 1.5mm to 6.0mm. The most commonly used thicknesses for channel letter faces are 2mm and 3mm, while 4mm–6mm is used for structural or framed display panel applications.

Can extruded acrylic be cut with a laser cutter or router?

Yes. Extruded acrylic is compatible with CO2 laser cutters and CNC routers. It cuts cleanly with polished edges using laser, and can be routed or scored-and-snapped for straight cuts. Note that extruded acrylic has a lower heat resistance than cast acrylic, so laser settings should be adjusted to avoid excessive melting.

What Are Luminao & Extruded Acrylic Sheets?

Luminao and Just Extruded Acrylic are continuous-extrusion acrylic sheets that offer a more economical alternative to cell-cast acrylic. The extrusion process produces sheets with very consistent thickness tolerances, excellent surface flatness, and good optical clarity — making them a reliable choice for channel letters, LED lightboxes, and general signage applications.

Available in Clear and Diffuser White finishes, thickness from 1.5mm to 6.0mm, and standard 4×8ft (1220×2440mm) sheet size.

Cast vs. Extruded Acrylic: When to Choose Which

Property	Just Cast Acrylic	Luminao / Extruded
Optical Clarity	Superior	Good
Thickness Consistency	Good	Excellent
Chemical Resistance	Higher	Standard
Thermoforming	Excellent	Good (lower temp)
Price	Higher	More affordable
Best For	Premium displays, high-end signage	High-volume signage, everyday channel letters

Practical tip: For high-volume LED channel letter orders, extruded acrylic's consistent thickness ensures predictable light diffusion — making production runs faster and more uniform.
