PET Bottle Insufficient Top Load Strength
Sorun Belirtisi
Bottles deform after stacking, collapsed bottles.
Neden Analizi
Unreasonable wall thickness distribution (locally too thin), insufficient stretch orientation, excessive lightweight design; insufficient blowing pressure leads to insufficient orientation.
Çözüm
①Optimize wall thickness distribution (lamp zone adjustment); ②ensure high-pressure blowing orientation; ③top load test monitoring; ④verify top load while lightweighting.
Temel Çıkarım
Lightweighting forces top load management.
