Recent Technical Trends of Automotive Painting

Abstract

In today's automotive painting, further reduction of carbon dioxide, volatile organic compound (VOC) emissions and multi-color paint is required. As a solution to contribute in the solving the problem, recent automotive paint technologies are described. For the atomizer, four technologies are described: high paint flow technology by high performance air motor, spray pattern width control technology which can contribute to reduction amount of over spray paint, flushable cartridge system which can contribute to reduction of the paint booth area and multi-color paint and the contamination proof system for the electrostatic atomizer with water borne paint. The paint robot, a wall-mounted robot which has wide moving area and high acceleration is described. This robot can contribute to reduction of the paint booth area. The painting control technology, a general configuration, the basic control methods, the delay compensation and recent monitoring system are also described.
