PETG '2079851475616104452 insufficient filling, short shot
Problem Phenomenon
During PETG '2079851475616104452, the cavity is not completely filled and the product is incomplete.
Cause Analysis
Injection pressure or speed insufficient, melt temperature low and flowability insufficient, gate or runner size too small, mold temperature low and melt solidifies early.
Solution
Increase injection pressure and speed; increase melt temperature to 240-260°C; enlarge gate and runner dimensions; appropriately increase mold temperature.
Key Takeaway
PETG short shot is mainly due to excessive flow resistance or insufficient melt flowability.
