Uneven pellet size of PCTG raw material
Problem Phenomenon
Large size differences of raw material or color masterbatch pellets cause uneven mixing.
Cause Analysis
Different components have different particle sizes and densities, uneven mixing in the hopper.
Solution
Use size-matched raw materials; premix before adding to the hopper; meter and feed separately.
Key Takeaway
Uniform PCTG mixing is the prerequisite for product consistency.
