ZHENHUA Vacuum’s ZBM1819 Headlamp Protective Film Solution
In the wave of vehicle electrification and smartization, headlamps have evolved from mere “illumination devices” into key components for brand identity. Automakers and their suppliers are now pursuing higher gloss, finer texture, and more stable finish. At the same time, stricter regulations on VOCs, hazardous substances, and energy consumption are being enacted worldwide. Traditional spray-painting processes are lengthy, energy-intensive, costly to control, and prone to defects such as color deviation — making consistent yield and stability hard to guarantee. The industry urgently needs a headlamp coating solution that balances environmental compliance with mass-production efficiency.
1. One Machine Completes Aluminum Coating + Protective Film — Streamlined Process
To address the drawbacks of traditional spray painting — including long process chains, numerous steps, heavy pollution — ZHENHUA Vacuum introduces the ZBM1819 headlamp protective film system. In a vacuum environment, it integrates aluminum evaporation coating and subsequent protective film deposition in a single equipment, building a high-quality reflective and protective structure for headlamps in one step.
Traditionally, headlamp reflectors and related components require multiple wet-process steps: primer, base coat, baking, aluminum spraying, and protective top coat. This complex chain occupies large floor space, requires extensive labor and energy, and generates significant VOCs and paint mist. In contrast, the ZBM1819 system performs:
Vacuum evaporation aluminum coating and protective film deposition in the same chamber with a single clamping;
Entirely vacuum-based processing — no wet spray painting — drastically reducing organic solvent usage and exhaust emissions, enabling a cleaner and more environmentally friendly production method.
By adopting ZHENHUA Vacuum’s ZBM1819 headlamp protective film solution, manufacturers can shorten the production chain, save plant space and labor, and — while complying with environmental regulations — significantly improve coating uniformity and coating reliability.
Test indicators:
Adhesion: 3M tape adhesion test shows no peeling; cross-cut adhesion test reveals less than 5% coating removal.
Silicone oil resistance: After marking with water-based ink pen and wiping, line thickness remains unchanged.
Corrosion resistance: After 10 minutes exposure to 1% NaOH solution, coating shows no signs of corrosion.
Water immersion test: 24 h immersion in 50 °C water — no delamination observed.
2. Tailored for PC / PC+ABS High-gloss Injection Molding — One Solution for Mainstream Headlamp Substrates
The ZBM1819 solution is designed specifically for high-gloss injection molded parts made of PC or PC+ABS. While ensuring a high-gloss finish and fine appearance, it also provides a dependable metallic reflective layer and protective film. Even under challenging conditions — high temperature, high humidity, chemical exposure — the headlamp remains bright, maintains its texture and visual quality, and retains structural integrity.
3. Conclusion
In the current era of accelerating intelligent vehicles and tightening environmental regulations, simply being able to produce is no longer sufficient. “High quality, low emissions, and high efficiency” have become the new standard for the headlamp industry. ZHENHUA Vacuum’s ZBM1819 headlamp protective film solution, employing an integrated vacuum “evaporative aluminum coating + protective film” process, simplifies traditional spray-paint sequences, reduces VOC emissions and overall costs, and — after stringent tests of adhesion, corrosion resistance, and water/humidity resistance — delivers both environmental compliance and quality upgrades. Looking ahead, as headlamp designs evolve toward more complex shapes and functional integration, ZHENHUA Vacuum’s headlamp protective film solution will offer automakers and supply-chain partners stable coating quality and greater peace of mind in environmental compliance
