Masterbatches (color concentrate pellets)
Liquid colorants for specific tones
Pre-colored granules for consistent output
🎯 SOS machines handle color additives effortlessly, giving you even color distribution, streak-free finishes, and vibrant results.
From red lunch boxes to black auto parts, color makes your product stand out—and we make sure your machine handles it smoothly.
