Q

LDPE '2079851475616104452 Sink Mark

A

LDPE sink marks are investigated along the three lines of holding pressure, temperature, and structure; lowering temperature to reduce shrinkage is a characteristic measure of polyolefins; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent r...

Q

LDPE '2079851475616104452 Weld Line

A

LDPE weld line treatment mainly relies on temperature and position; high-flow materials also need a gate strategy; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Q

LDPE '2079851475616104452 Shrinkage Allowance

A

LDPE mold allowance is a function of density; the trial mold correction route is more practical than theoretical calculation; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
