Gate freezing blockage in PLA '2079851475616104452
Problem Phenomenon
PLA at the gate cools and crystallizes too fast, causing blockage.
Cause Analysis
The temperature of the mold gate area is low (<60°C), and PLA crystallizes and solidifies prematurely, blocking the gate.
Solution
Raise the mold temperature in the gate area; increase the gate size; appropriately increase the injection speed.
Key Takeaway
PLA gate freezing is related to low-temperature crystallization.
