Q

LLDPE '2079851475616104452 sink mark

A

LLDPE's low shrinkage reduces sink marks; but holding pressure management for thick-wall parts remains a necessary step; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Q

LLDPE '2079851475616104452 weld line

A

LLDPE weld line performance is better than LDPE; but design avoidance remains a basic requirement for structural parts; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Q

LLDPE '2079851475616104452 shrinkage and warpage

A

LLDPE's low shrinkage reduces but does not eliminate warpage; uniform wall thickness and balanced cooling remain fundamental engineering; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
