Insufficient Actual Weight in PBT '2079851475616104452
Problem Phenomenon
The actual weight of the product is less than the theoretical weight (insufficient density).
Cause Analysis
The holding is insufficient and the product is not dense enough; the injection amount is insufficient; the material degrades and the density decreases.
Solution
Increase the holding pressure and extend the time; ensure the injection amount is sufficient; reduce the processing temperature.
Key Takeaway
PBT weight is an intuitive indicator of product quality.
