Custom Acrylic Bending & Forming

P&M Plastics specialises in custom acrylic bending and forming, transforming flat acrylic sheet into precision-curved components for industrial, commercial, and architectural applications. Whether you need a simple 90° guard, a multi-bend machine cover, a sweeping architectural curve, or a custom boat windscreen, our Gold Coast facility has the equipment and expertise to deliver.

Large-format and complex compound curves

The jobs that need real expertise are the big ones: a full-size boat windscreen, a curved architectural panel, a wrap-around display, a domed cover. Large sheets hold heat unevenly, sag under their own weight, and show every ripple or stress mark once they cool. Our oven takes sheets up to 3 x 2 metres, so we can form large panels in a single piece, with optical clarity from edge to edge, rather than joining smaller sections.

We form large-format acrylic and Perspex over custom-built moulds and bucks, matching compound (double) curvature, tight sightlines, and existing profiles. Where a screen or canopy already exists, we can reverse-engineer the curve and reproduce it. Whether it is a one-off replacement or a short production run, the process is controlled end to end: pattern, former, heat, form, cool, trim, and polish.

This is the work behind marine windscreens and hatches , architectural glazing and feature panels, retail and museum display curves, lighting diffusers, and transport glazing. If it is large, clear, and curved, it is exactly the kind of custom fabrication we are set up for.

Acrylic bending is about more than just heating and folding plastic.

Done poorly, it results in cracking, hazing, bubbles, and internal stress that leads to premature failure. Our process controls the heating rate, forming temperature, bend radius, and cooling cycle to produce stress-free bends with crystal-clear optical quality.

We use three primary forming methods depending on your application.

Strip heating (line bending) uses a narrow heating element to create precise straight-line bends: ideal for guards, machine covers, brochure holders, display stands, and box-style enclosures. We strip-bend acrylic from 2mm to 25mm thick with angle accuracy of ±0.5°.

Oven forming heats the entire sheet uniformly, allowing complex compound curves, domes, and free-form shapes. This method is used for boat windscreens, light diffusers, curved architectural panels, and display features that require smooth, flowing curves rather than sharp fold lines.

Drape forming uses gravity and moulds to create controlled curves over a specific shape: perfect for repeatable production parts like curved guards, covers, and light lenses.

Acrylic is the preferred material over polycarbonate when optical clarity matters. Cast acrylic transmits 92% of visible light (compared to ~88% for polycarbonate), doesn't yellow under UV exposure, and is easier to polish to a glass-clear finish.

For applications like retail displays, museum cases, light diffusers, and architectural glazing, acrylic's clarity and longevity make it the superior choice.

We regularly produce custom guards for machinery, curved covers for electrical and mechanical equipment, formed light diffuser panels, boat windscreens in clear and tinted acrylic, architectural feature panels, display curves for retail and hospitality, and sneeze guards with formed edges. Every formed component is inspected for optical clarity, dimensional accuracy, and surface quality before dispatch.

Recent project: a curved perspex boat windscreen

We recently reproduced a compound-curved boat windscreen from scratch in optically clear acrylic, building a custom MDF mould to match the original screen and drape-forming the heated sheet over it. See the full curved perspex boat windscreen case study for how the job came together, from former to finished, polished screen.
