PETG '2079851475616104452 filling end weld strength
Sorun Belirtisi
The weld strength at the filling end of the product (end meeting point) is severely insufficient.
Neden Analizi
At the end, the melt temperature has decreased and flowability is poor; the two flow fronts converge at low temperature and fuse poorly.
Çözüm
Increase the melt temperature; optimize gate position to reduce end welding; strengthen venting in that area.
Temel Çıkarım
PETG end welding is the weakest link in filling.
