Custom Polycarbonate Windshield

Manufacturers’ Insight and Tips

Introduction

As the automotive industry races toward light weighting and enhanced safety, polycarbonate (PC) windshields are emerging as a game-changer—offering 250x the impact resistance of glass at half the weight.

Why choose polycarbonate (PC) as the material for windshields?

Except the light weight and supper impact resistance, polycarbonate sheet is with excellent light transmittance ≥ 90% and weather resistance (optional UV coating to prevent yellowing).
What’s more, the polycarbonate sheet is easy to process, and design flexibility, can be injection molded and hot-bent into complex curved surfaces( such as racing streamlined windshields)

What factors should be considered when manufacturing polycarbonate windshield?

To ensure the durability and protection, some key technologies are important for manufacturing polycarbonate windshields.

1. Production process

Injection molding: suitable for mass production (such as motorcycle windshields, like nationalcycle, the biggest company of motorcycle windshields), high-precision molds are required to control thickness uniformity.
Hot bending: used for curved glass of boat window/racing cars, precise temperature control is required to avoid internal stress( such as golf windshields).
Multi-layer composite technology: PC+PU interlayer improves bulletproof performance (military-grade application)( such as bulletproof glass).

2.Surface treatment

Abrasion resistant coating: Improve surface hardness. EXCELITE’s hard coating provides scratch resistance, long-lasting durability and superior performance even in the most extreme conditions, our abrasion resistance polycarbonate sheet support thermoforming process.
Anti-fog/anti-ultraviolet coating: Nano-coating technology meets special environmental requirements (such as polar vehicles). EXCELITE’s performance anti-fog polycarbonate sheet can withstand harsh weather.

3.Quality control

Optical inspection: Automated system detects bubbles and impurities (in accordance with ISO 9001 standards).
Environmental testing: Salt spray test, high and low temperature cycle (-40℃~120℃) to verify durability.

How to Choosing a Polycarbonate (PC) Windshield Manufacturer?

By following below 5 tips can help you choose the best manufacturer of windshiled.

1. Material Grade & Traceability
Raw Materials: Virgin (non-recycled) PC resin from top-tier suppliers with UL certification and full batch traceability

2. Manufacturing Precision, make sure your post-assembly.

Method	Application	Tolerance
Injection Molding	Complex geometries (e.g., motorcycle windscreens)	±0.05mm wall thickness
Multi-layer Co-extrusion	Bulletproof/soundproof laminates	Layer deviation <0.02mm
Thermoforming	Aircraft curved canopies	Arc error <0.3°

3. Surface treatment: Anti-scrach/ anti-fog coating etc, also if your windshield also involve silk-printing process, make sure the functional coating are compatible with your post-process.

4. Testing & Validation: like optical distortion /environmental aging /chemical resistance /thermal cycling etc

5. After-Sales Support
Warranty: like 5-year coverage (yellowing/coating failure)
Emergency Response:
▪ 24/7 technical support
▪ <72-hour air freight for urgent orders
