Digital Printing on Aluminum

Digital Printing Machine

Digital printing of water-based inks on the surface of aluminum sheet

The digital printing machine for aluminum is an industrial-grade device specifically designed for surface decoration and functional coatings on aluminum sheets. It combines digital inkjet technology with high-temperature curing processes. Its core technology uses high-precision printheads to spray special ceramic or metallic-based inks onto the aluminum surface. The printed aluminum is then subjected to high-temperature treatment (200-500℃), enabling the ink to fuse with the substrate, creating a highly adhesive, weather-resistant coating. This technology surpasses the limitations of traditional spraying and anodizing processes, allowing for complex patterns, gradient colors, and small-batch customization. It is widely applied in architectural facades, traffic signage, electronic devices, and industrial components.
