In automotive manufacturing, the quality of surface treatment is critical to both corrosion protection and overall finish. Jiangsu Suli Machinery Co., Ltd. addresses the coating requirements of automotive parts and BIW structures with a cutting-edge automated powder coating solution. This integrated system combines PT, ED, and intelligent robotic spraying to help automakers build efficient, environmentally friendly, and smart coating lines for the modern factory.
To meet the automotive industry's stringent requirements for corrosion resistance, Suli Machinery employs a multi-stage PT process—including degreasing, pickling, and phosphating—to efficiently remove oils and oxides from the workpiece surface, laying a solid foundation for subsequent electrophoretic coating. The supporting ED system utilizes high-performance cathodic electrophoretic deposition technology, forming a dense, uniform, and strongly adhesive protective film even in complex areas such as weld seams, edge flanges, and crevices. This significantly extends the vehicle's corrosion protection lifespan, enhances product reliability, and improves overall market competitiveness.
During the powder coating process, Suli Machinery integrates high-precision six-axis spraying robots and other advanced robotic systems e quipped with intelligent recognition and 3D trajectory planning. This enables precise and consistent coating of parts with varying sizes and complex geometries. Compared to traditional manual spraying, robotic coating delivers superior consistency and repeatability, minimizes powder waste, and eliminates solvent emissions. These benefits not only enhance coating quality but also significantly boost environmental sustainability and reduce operational costs, helping clients meet their net-zero carbon commitments and broader sustainability goals.
To date, Suli Machinery’s intelligent automotive coating lines have been widely adopted for the automated mass production of key components such as vehicle frames, chassis parts, doors, and bumpers. With a proven track record serving leading OEMs and suppliers, Suli is at the forefront of driving the automotive industry’s swift shift toward smarter, greener, and more flexible manufacturing.
We warmly invite partners from the automotive sector to visit Suli Machinery to explore innovative paths toward high-quality, sustainable manufacturing and to collaborate on shaping the future of intelligent, smart production.
