FIDAR System's cast clear acrylic sheets are manufactured using the cell-cast process, which produces superior optical clarity and tighter thickness tolerances compared to extruded acrylic. The result is a sheet with excellent surface quality, minimal internal stress, and outstanding machinability.
Cast acrylic is the preferred choice for applications where appearance and precision matter. Unlike extruded acrylic, the cast process allows for:
Cast clear acrylic is used across a wide range of industries and applications:
Cast clear acrylic can be cut, drilled, routed, laser-cut, and thermoformed. It bonds well with acrylic cements and can be polished to a high gloss finish. Remove protective masking only when the fabrication process is complete.
Cast acrylic is the industry standard for laser-engraved awards and recognition plaques. When the laser engraves the surface, the material turns a bright, clean white - creating sharp contrast for logos, text, and fine detail. The 2.8mm and 4.3mm thicknesses are most common for desktop awards.
Clear acrylic front panels for illuminated channel letter signs, cabinet signs, and backlit light boxes. The 92% light transmission allows interior LED strips or modules to project through the face evenly. Typically 2.8mm to 5.5mm depending on sign cabinet depth.
4.3mm (3/16") and 5.5mm (1/4") cast acrylic are the most common thicknesses for counter-mounted and freestanding sneeze guards in restaurants, pharmacies, reception desks, and checkout counters across Canada.
Thicker gauges - 9mm, 12mm, 18mm, and 25mm - are used by custom aquarium builders for panel tanks, display aquariums, and vivarium enclosures. Cast acrylic is preferred over glass for larger installations due to its lighter weight and ability to be fabricated with solvent cement joints.
Retail fixture fabricators use cast clear acrylic for brochure holders, product risers, shelf dividers, and countertop display cases. The material's optical clarity and ease of fabrication make it a go-to for custom retail display shops across Ontario and British Columbia.
Clear acrylic panels (9mm–12mm) are commonly used as machine guard panels on CNC equipment, presses, and automated assembly lines - allowing operators to see the process while being protected from chips and debris.
How to Fabricate Cast Clear Acrylic Sheets
Measure and mark
Mark cut lines on the protective masking film using a fine-tip marker or scoring tool. Keep the masking on throughout fabrication to protect the surface.
Cut to size
Use a circular saw with a fine-toothed carbide blade, a table saw, or a jigsaw with a plastic-cutting blade. Score-and-snap works for straight cuts on thinner sheets (up to 4.3mm).
Drill holes
Use standard HSS or brad-point drill bits at moderate speed. Apply light pressure and back the sheet with scrap wood to prevent chipping on exit.
Laser cut or engrave
For CO2 laser cutting, cast acrylic produces flame-polished edges and clean white engrave results. Use air assist to clear debris and reduce edge discolouration.
Bond with solvent cement
Apply acrylic solvent cement (such as IPS Weld-On 3 or 4) to join pieces. Capillary action draws the cement into the joint. Hold the joint in place for 30–60 seconds, then allow 24 hours for full cure.
Remove masking
Remove the protective masking film last, after all cutting, drilling, and bonding is complete. Polish edges with a buffing wheel and polishing compound if a clear, polished edge is required.
Thickness Selection Guide
| Thickness | Best For |
|---|---|
| 1mm – 1.5mm | Thin display overlays, framing inserts, light-duty protective covers |
| 2mm – 2.8mm (~1/8") | POP display panels, brochure holders, thin acrylic frames, small sign faces |
| 4.3mm (~3/16") | Sneeze guards, medium-duty display cases, light box faces, picture frame glazing |
| 5.5mm (~1/4") | Counter guards, retail display cases, partition inserts, signage panels |
| 9mm (~3/8") | Machine guards, thick display cases, safety barriers, heavy-duty framing |
| 12mm (~1/2") | Structural display units, thick panel glazing, aquarium side panels |
| 18mm – 20mm (~3/4") | Thick architectural panels, aquarium front and bottom panels, load-bearing displays |
| 25mm (~1") | Large aquarium panels, structural glazing, specialty architectural applications |
| Property | Cast Clear Acrylic Sheets | Extruded Acrylic |
|---|---|---|
| Thickness tolerance | ±0.4mm (tight, precise) | ±0.8mm (looser) |
| Surface hardness | Higher - more scratch-resistant | Slightly softer surface |
| Heat deflection | 95°C | 80°C |
| Laser engraving | Produces clean white/frosted result | Possible, but less consistent result |
| Chemical resistance | Better resistance to solvents | Adequate for most uses |
| Price (per sheet) | Higher - premium material | Lower cost |
| Thin gauge availability | 1mm minimum | 2mm minimum, but lower cost at 2–3mm |
Cast acrylic is manufactured by pouring liquid PMMA monomer into glass molds and curing it slowly. This produces tighter thickness tolerances (±0.4mm), better surface hardness, a higher heat deflection temperature (95°C vs. 80°C), and superior laser engraving results. Extruded acrylic is pushed through a die at high speed, making it lower cost but with slightly looser tolerances and a softer surface. For professional fabrication, signage, and aquariums, cast is the standard choice. For high-volume laser cutting where cost matters, extruded is a reasonable alternative.
Yes - cast clear acrylic is one of the best materials for CO2 laser cutting. The laser produces a smooth, flame-polished edge that requires no secondary finishing, unlike machined edges. When laser engraving (rather than cutting), cast acrylic produces a clean, bright white frosted result - ideal for awards, nameplates, and engraved signage.
The most commonly used thicknesses for counter-mounted sneeze guards in Canada are 4.3mm (3/16") and 5.5mm (1/4"). The 4.3mm is suitable for most retail counter and reception desk applications. The 5.5mm is preferred for wider panels or freestanding barriers where additional rigidity is required.

There is no minimum order quantity on standard-size cast clear acrylic sheets. You can purchase a single sheet at the listed per-sheet price. Volume pricing is available for orders of 10 or more sheets of the same SKU - contact us for a bulk quote.
Yes. Cast acrylic can be thermoformed using a strip heater, line-bending tool, or oven. The material becomes pliable at approximately 140°C–180°C and holds its formed shape once cooled. It is suitable for creating bends, curves, and simple formed shapes. Thinner sheets (2mm–5.5mm) are most commonly thermoformed.
Cast acrylic has moderate UV resistance but it is not UV-stabilized unless specifically noted. For extended outdoor exposure, we recommend using a UV-resistant protective coating or selecting a UV-stabilized variant. For outdoor signage in direct sun, cast acrylic is commonly used with the understanding that it may yellow slightly over many years without UV protection.
