We transport the three roller machine to the customer, and after the customer receives the goods for inspection, they immediately use it to grind various paint colors, including red, yellow, and blue. And each color also has a different depth and saturation, which requires very high machine requirements. Once there is an error, it will waste a production line of coating materials. Our three roller machine, under professional operation, can accurately control each color difference and grind out the colors required by customers with the smallest and most accurate color difference.
