Q

Uneven surface gloss of homopolymer polypropylene injection products

A

Uneven gloss reflects inconsistency of mold surface condition and melt flow; it needs to be improved from three aspects: mold polishing, temperature uniformity, and injection process.

Q

Weld lines on homopolymer polypropylene injection products

A

Weld lines are a manifestation of poor fusion at melt convergence; melt fusion quality is improved by increasing melt temperature, injection speed, and mold temperature.

Q

Warpage deformation of homopolymer polypropylene injection products

A

Warpage deformation is the core challenge of '2079851475616104452 crystalline materials; its essence is internal stress caused by non-uniform shrinkage, requiring systematic control from design, process, and mold in multiple dimensions.

Q

Sink depressions in thick-wall areas of homopolymer polypropylene injection products

A

Sink depressions are a typical defect of '2079851475616104452 crystalline materials; the root cause is local volume shrinkage not being effectively compensated, requiring coordinated solutions from holding pressure parameters, gate design, and cooling conditions.
