Mold Vent Groove Blockage of PBT
Problem Phenomenon
After long-term production, the vent grooves are blocked by PBT volatiles and dust, and the venting effect decreases.
Cause Analysis
Low-molecular substances and additives accumulate in the vent grooves, and they become blocked if not cleaned for a long time.
Solution
Regularly clean the vent grooves with special cleaning tools; reduce the processing temperature to reduce volatiles.
Key Takeaway
PBT vent groove maintenance is a guarantee for long-term production.
