​Inconsistent pellet size is one of the most frequent quality issues in twin screw pelletizing lines. It affects downstream handling, packaging uniformity, and customer acceptance, especially in recycling and compounding applications where pellet appearance is closely inspected.

​A plastic color mixer machine looks simple from the outside, but it combines rotating parts, electrical power, heavy materials, and airborne dust in one workstation. Most incidents happen during routine actions such as feeding, cleaning, inspection, or clearing a jam, not during normal mixing.

​Color consistency and material uniformity are critical factors in plastic processing. Whether producing molded parts, extruded products, or recycled pellets, uneven color distribution or poor additive dispersion can directly lead to quality complaints, higher scrap rates, and unstable downstream processing.
