In the past ten years, under the influence of auto parts suppliers, the auto industry has also adopted UV LED curing technology. The current application of UV LED curing technology in the automotive industry mainly involves: automotive headlight lenses, reflectors, seat belts, center consoles, instrument panels, car interior wooden decorations, instrument panels, screen printing on measuring instruments, cylinder heads Part gaskets, steering wheels, adhesives for sound insulation pads, dark box parts, brake linings, clutch pads, wheels and windows, etc. The above mentioned are not all the application parts of UV LED curing technology in the automotive industry, but also include some three-dimensional objects and some parts outside the car. UV LED light curing of car headlight lens varnish because polycarbonate lens has high elasticity, is easy to design and light weight, it replaced the traditional glass lens many years ago. However, polycarbonate has poor wear resistance and yellowing, so varnish must be applied to its surface during use. The UV LED curing coating just meets this demand, such as high hardness, chemical resistance, and light resistance. Compared with traditional thermal curing, UV LED curing technology has many advantages, such as greatly reducing the processing time, reducing the footprint of the equipment, and increasing the anti-fouling ability of the coating film and the substrate during curing. The car headlight lens coating curing system has successfully achieved a breakthrough in the application of this technology to the exterior parts of the car.
Mirror varnish UVLED curing
Automobile mirrors are generally made of plastic and must have a light emitting surface. The completion of the painting of the automotive reflector usually requires a multi-step UV LED processing process. First, the plastic surface is irradiated by UV LED light to increase its surface tension, so that the varnish has good fluidity and adhesion on the plastic surface. The surface of the varnish in the non-reflective area after the coating is cured by UV LED light is very smooth, which makes the metal treatment of the surface in the vacuum deposition chamber very convenient. If the metal-treated surface does not have a vacuum deposited protective layer, it can be painted again with UV LED. It can be seen that the application of UV LED varnish to the above treatment process is very effective. Moreover, UV LED curing not only takes a short time, but also has a small production area and excellent coating performance. The varnish UV LED curing of the instrument panel The instrument panel and various parts like the center console also need UV LED curing technology for coating for aesthetics. Wood material looks very familiar with plastic after being treated in this way. In addition, the UV LED cured film has effective high mechanical strength. After the coating of each component, it passes through the area of several LED UV curing equipment and is cured by UVLED light.
