Q

PEEK Compression Molding Particle Boundary Marks as Weak Lines

A

Pellet molding boundary marks are congenital weak lines; fine powder plus directional avoidance is the response; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference...

Q

Missing Shutdown Purging Procedure for PEEK

A

Shutting down with material in the barrel is a big taboo for PEEK — purging with HDPE is only complete when the droplets are clean; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Q

Actual Measurement Calibration of PEEK Melt Temperature

A

PEEK process transfer is based on the actually measured melt temperature, and set values are for reference only; 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 refe...

Q

Nozzle Temperature and Cold Slug of PEEK

A

Matching the nozzle temperature to the front zone is a hard requirement, and the cold slug well receives the front cold material; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a tro...

Q

Shutdown Thermal Stability Management of PEEK

A

PEEK shutdowns are handled in 1-hour/3-hour graded levels, and the first shot after restart must be scrapped; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Q

Particle Contamination of PEEK Semiconductor Parts

A

The competitive dimension of semiconductor PEEK parts is cleanliness control; tracing particle contamination must cover the entire chain from processing to packaging; ultrasonic cleaning is the standard post-treatment process.

Q

Poor Color Powder Dispersion in High-Mixing PEEK

A

For PEEK coloring, the dedicated color masterbatch granule route is preferred; directly adding color powder to a narrow-window material is high risk; the balance point between dispersion and degradation needs to be determined by testing.

Q

Shutdown Carbonization Failure of PEEK

A

The core of PEEK shutdown management is dual control of time and temperature; 15 minutes is the empirical red line; the cost of discharging material at shutdown is far lower than batch scrap caused by degraded material mixing in.
