Hello: I have a problem with the extrusion of PP Strap Band. We always extruder one strap at a time, but when we change to a die with two exits for two straps at the same time, the straps have different width, 2 mm difference, so we have clean the die, and give more temperature to the die side that the strap have less width, but nothing happens, still the same problem. Any Idea? Thank you Antony ------------------ IP: Logged |

Look for sources of imbalance. Heaters Extremely small differences in geometry from side to side, especially in narrow gaps, can cause imbalance. Tom C IP: Logged |
