The on-line coating process line is completely closed, and the in-line coating process is performed after the vehicle body is baked at 204°C and then the plastic parts are mounted on the vehicle body, and then the primer and topcoat are processed together. There is a danger of dust sticking in the installation of the plastic parts of the in-line painting process, and the cost of parts mounting on the painting line is relatively high. Therefore, for the car factory, the best process should be online coating. At this time, the plastic is required to withstand a high temperature of 180 to 204° C. and it can be coated with the same paint and process as the metal.
In addition, reducing the drying temperature of the electrophoretic paint can save energy, lower electrophoretic paint has been achieved 10min, 120 ~ 140 °C curing electrophoretic paint is to explore the middle line coating process is to separate the metal body and plastic parts of the coating. The painting of plastic parts can be done in a plastics processing plant. The automobile factory will assemble the painted plastic parts. This process avoids high temperature issues and is a very good solution for parts that do not have color consistency requirements. However, when the plastic parts are required to have the same color as the metal body, it takes a very long time and economic cost to meet the automotive industry's high requirements for color tone. BASF Coatings believes that off-line coating is a promising process, and the problem of color consistency will be solved by the uniform deployment of metal and plastic basecoats.
Body parts must provide flawless visual effects. For the exterior of the car body, the entire structure is integrated, and the visual effect “looks like a single casting†remains a mainstream trend. For example, the new Beetle cannot be seen at all from the outside, and its fenders, bumpers and fuel tank flaps are all made of plastic. Therefore, Class A surface requirements can be achieved, and online coating is possible. The main direction of development.
the Lipstick Tube was produced by PC/ABS/PMMA/SAN/PCTA/PP, and we can adjust any color for client during plastic injection. The surface also can be different treatment color. Its size is 22.8*83.2MM, and surface treatment is electronic plating. There is also a bullet version. The capacity can be changed at 4.7g, 4,4g, 4.2g by use different inner cup. The molds are existed, so we can produced for client at anytime. And it is good for us to control the quality and timing.
