Q

LLDPE '2079851475616104452 sink marks

A

Sink mark = compensation feeding.

Injection Molding LLDPE; '2079851475616104452; sink mark; holding pressure; thick wall

Q

LLDPE '2079851475616104452 flash

A

For flash, first reduce pressure.

Q

LDPE '2079851475616104452 Warpage

A

LDPE warpage treatment is the same as HDPE; uniform wall thickness plus balanced cooling is the basic engineering; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Q

LDPE '2079851475616104452 Flash

A

LDPE flash is the price of low viscosity; mold accuracy and pressure control are the two major defense lines; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

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

Q

LDPE Injection Molded Container

A

LDPE containers are designed structurally according to stacking; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems in the future

Q

LDPE Melt Pressure

A

Weight stability relies on melt pressure management; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; Incorporate this case into the defect archive as a troubleshooting reference for similar future problems.
