Lamp is one of the important parts of the car, and lamp reflector surface treatment, can enhance its functionality and decorative, common lamp cup surface treatment process has chemical plating, painting, vacuum coating.
Paint spraying process and chemical plating is the more traditional lamp cup surface treatment process.
(1) Paint spraying process is simple to operate, low equipment costs, applicable to a variety of shapes and sizes of the lamp cup, but the coating is susceptible to erosion by the external environment, resulting in fading, peeling and other phenomena, reducing the service life of the lamp.
(2) Electroplating is to form a layer of metal plating on the metal surface of the headlight cup through electrolysis, which can improve the corrosion resistance, abrasion resistance and appearance quality of the headlight cup. However, the plating process may have pores in the coating, long-terexposure to harsh environments may lead to corrosion. The process also has a certain impact on the environm produce harmful wate water and exhaust gas.
With the market for automotive decorative and functional performance is getting higher and higher, as well as people’s awareness of environmental protection, at present, the most in line with the lamp reflector environmental and technological requirements of the surface treatment process is characterized by environmental protection vacuum coating process. The lamp reflector plated by vacuum coating process has the advantages of high reflectivity, good weather resistance, excellent film uniformity and more stable and consistent reflective effect.
Zhenhua lamp coating solution–ZBM1819 lamp protection film equipment
Zhenhua developed the lamp protective film equipment to solve the PC / ABS lamps have long been required to spray paint trouble, can make the lamp injection molded parts directly into the vacuum chamber to complete a one-time vapor deposition as well as the protective film plating process, to prevent secondary pollution, without the need for bottom spraying or surface spraying. Equipment plating film uniformity is good, its acid resistance, alkali resistance, salt spray resistance, waterproof and other indicators are in line with international standards, this equipment has been widely used in the market by domestic and foreign brands of headlights manufacturers, the production of a number of brands of headlights.
Equipment process
Substrate (PC/ABS/PMMA) – Cleaning – Deposition of protective film layer – Immersion of metal plating layer -Deposition of protective film layer.
Test index
1.Adhension testing：no shedding after direct gluing; the shedding area after cross- cutting is less than 5%;
2. Silicone Oil Performance: the thickness of the water-based marker pen changes;
3. Corrosion resistance test：wfter 10min titration with 1%NaOH, the coating is non- corrosive.
4.Water immersion test：immersing into warm water at 50 for 24h, the coating does not fall off
