Buyers of sports cars often are willing to spend significant sums of money for a more customized ride. BMW is showing off a new overspray-free painting process that allows the automaker to use several different paint colors and designs without using stencils or having to mask the vehicle off. Without resorting to stencils or masking, the painting process is much faster and less time-consuming, and expensive.
The first use of the new paint technology is being conducted with 19 different BMW M4 coupes rolling off the assembly line at the Dingolfing assembly plant. The run of cars has custom two-tone paintwork with M4 identification on the hood and trunk. BMW developed the EcoPaintJet Pro application process for waterborne base coats and 2K clearcoat with help from mechanical and plant engineering company Durr.
Innovative Painting Technology
The new process doesn’t require electrostatics, which is required in conventional painting processes. Rather, the new process relies on jet application with the paint applied using an orifice plate that allows high definition with variable paint thickness between one and approximately 50 millimeters. This innovative method enables two different paint colors to be used to create contrasting roofs, stripes, and other intricate designs. The precision of the jet application ensures that the paint is applied only where needed, reducing waste and environmental impact.
The EcoPaintJet Pro technology is not only about aesthetics but also about sustainability. Traditional painting methods often result in significant paint waste due to overspray, which can be harmful to the environment. By eliminating overspray, BMW’s new process minimizes the amount of paint used and reduces the need for extensive ventilation and filtration systems in the paint shop. This leads to lower energy consumption and a smaller carbon footprint.
Customization and Efficiency
Customization is a key selling point for luxury and sports car buyers. The ability to offer unique paint jobs without the need for stencils or masking means that BMW can provide a higher level of personalization for its customers. For example, a buyer could choose a custom two-tone paint job with intricate designs that reflect their personal style. This level of customization was previously only available through aftermarket modifications, which can be costly and time-consuming.
The efficiency of the new painting process also translates to cost savings for BMW. By reducing the time and labor required for painting, the automaker can produce customized vehicles more quickly and at a lower cost. This efficiency can be passed on to the customer in the form of more competitive pricing or additional customization options.
Moreover, the EcoPaintJet Pro process is versatile and can be adapted for use with different types of paint, including metallic and matte finishes. This flexibility allows BMW to experiment with new colors and textures, further enhancing the appeal of their vehicles.
In addition to the environmental and economic benefits, the new painting process also improves the quality of the paint job. The precise application of paint ensures a smooth, even finish with fewer defects. This results in a higher-quality product that meets the high standards expected by BMW customers.
In conclusion, BMW’s new overspray-free painting process represents a significant advancement in automotive painting technology. By eliminating the need for stencils and masking, the process is faster, more efficient, and more environmentally friendly. The ability to offer highly customized paint jobs without the associated costs and time constraints is a major selling point for luxury and sports car buyers. As BMW continues to refine and expand the use of this technology, it is likely to set a new standard for the industry.
