Custom Projects
We turn your ideas into reality. Whether it’s a small custom order or a large-scale production. Our team works closely with you to manufacture products exactly to your specifications, ensuring top-quality results every time.
Unique challenges are welcomed and we will provide flexible manufacturing options tailored to your needs. In most cases, no minimum order quantity (MOQ) applies, making it easy for designers, engineers, and OEMs to develop new products, or innovative lighting solutions.
Description
The process begins with a detailed review of your design requirements, drawings, or performance goals. Our engineering team then recommends the most suitable materials, optical structures, and fabrication methods. Once specifications are finalized, samples or prototypes are produced for validation. After approval, production scales up to full manufacturing, maintaining consistent quality through precision cutting, machining, and optical testing. Throughout every stage, you receive dedicated technical support and clear communication to ensure your project achieves the desired light diffusion, reflection, or transmission performance.
Bellow are some examples of recent projects:
Diffusers And Prism
UGR>19 prismatic sheet with TP(b) fire rating and anti UV coating.
- Prismatic sheet with opal appearance according to custom light transmittance and thickness.
- Custom extrusion roller to manufacture the prism type required by the customer.
- Flexible opal diffuser lens with TPE hooks for linear light fixture up to 30M long.
- Thermoformed diffuser sheet.
Lights Guides
Laser engraved light guide in long format: 19ft long with a narrow width.
- Large area light guide with high uniformity: 6x2meters including the back reflective sheet and the front diffuser. All bonded to an aluminum plate for easy assembly.
Special Lenses
VO fire rated polycarbonate, tinted color, anti-scratch surface for medical device.
- Linear light with batwing light distribution linear.
- Black diffuser lens. When the light is turned on, the black sheet turns opal as any standard white diffuser.

Available options include:
- Milling to create steps, grooves, or custom profiles
- CNC machining for precise shapes and patterns
- Laser cutting for smooth edges and complex geometries
- Saw cutting for standard sizing and trimming
- Bonding and assembly of multiple sheet layers
- Edge finishing with chamfers, bevels, and rounded edges
Materials: Comparison of PMMA, PC, and PS
Use this comparison table to quickly understand the differences and find the best option for your lighting project.
| Property / Feature | PMMA (Acrylic) | PC (Polycarbonate) | PS (Polystyrene) |
|---|---|---|---|
| Light Transmission | Very high | High | High |
| Impact Resistance | Low – brittle, can crack under stress | Very high – shatter-resistant | Low – brittle |
| Heat Resistance (Continuous Use) | 80–90°C | 120°C | 70°C |
| Maximum Short-Term Heat | ~100°C | ~135°C | ~80°C |
| UV Resistance / Weathering | Good (can yellow over long-term) | Moderate UV stability (However we add UV stabilizer) | Fair (Prone to yellowing)However we add UV stabilizer. |
| Flammability / Safety | Moderate (UL94 HB) | Better (UL94 V-2/V-0 with additives) | Moderate (UL94 HB) |
| Chemical Resistance | Good (resistant to mild acids/alkalis) | Excellent – resists most chemicals | Poor – sensitive to solvents |
| Weight / Density | 1.18 g/cm³ | 1.2 g/cm³ | 1.05 g/cm³ |
| Processing / Fabrication | Thermoforming, laser cutting, CNC. | Good for thermoforming, no laser cutting, CNC. | CNC. |
| Cost | Medium | High | Low |
| Durability / Lifespan | Moderate – good indoor use | Very high – suitable for harsh/industrial environments | Fair – medium-term indoor use |
| Common Applications | Office LED panels | Industrial/warehouse lighting, outdoor luminaires, impact-prone areas | Cost sensitive projects |
Product Tolerances
The 3 material (PMMA, PC and PS) have similar tolerances.
| Property | Value |
| Thickness | ±3% |
| Mother board Length / Width | ±3.0 mm |
| Cut-to-Size Length / Width | ±0.3 mm |
| Light Transmittance & Haze | ±2% |
Note: PMMA has the highest thermal expansion coefficient among diffuser materials. This means it can expand in hot conditions and contract in cold conditions. Use our Thermal Expansion Calculator to predict the final dimensions before installation.
Packing
At Hexatron Technologies, we take great care in packing our diffuser sheets to ensure they reach our customers in perfect condition. Proper packaging is critical for maintaining surface quality, optical performance, and dimensional accuracy during storage and transportation.
1. Standard Sheet Packing
- Mother Sheets: Large sheets (up to standard extrusion sizes) are stacked on pallets or crates.
- Final Cut / Cut-to-Size Sheets: Smaller sheets are carefully wrapped and separated with protective films or kraft paper, then bundled to avoid bending or warping.
2. Protection Methods
- Surface Protection Film: All diffuser sheets are supplied with a removable protective film to prevent scratches and contamination.
- Edge Guards / Corner Protectors: To prevent chipping or denting during handling and shipping.
3. Palletization & Securing
- Sheets are stacked on pallets or crates with interleaving layers and secured with straps or stretch film to prevent movement during transit.
- Maximum stack height is calculated based on sheet thickness and material to avoid warping or deformation. A pallet of 1.5 tons is the maximum weight.
4. Shipping & Handling Recommendations
- Flat Storage: Sheets should be stored flat and supported evenly to maintain flatness.
- Climate Considerations: Avoid prolonged exposure to extreme temperatures or humidity, especially for PMMA, to prevent dimensional changes.
- Handling: Use gloves when removing protective film to prevent fingerprints.
