Q

ASA insufficient drying silver streak

A

90% of ASA silver streaks originate from insufficient drying; 3~5 hours drying is a supplier specification rather than a suggestion; if the moisture problem is not solved, any process adjustment is only treating the symptoms.

Q

AEPDS drying management

A

AEPDS drying management refers to ABS but needs adjustment; verification ensures quality; prevent both excess and insufficiency.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Q

ABS weld line bubble

A

For ABS weld line bubbles check venting and drying; 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 for similar problems later

Material Drying weld line bubble venting convergence drying

Q

ABS dimensional deviation

A

ABS dimensions rely on parameter locking and SPC monitoring; 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 for similar problems later

Material Drying dimensional deviation shrinkage SPC parameters

Q

ABS bubble

A

ABS bubbles are divided into three types, distribution points to the cause; 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 for similar problems later

Q

ABS silver streak misjudged as venting

A

For ABS silver streaks look at distribution first, overall random means moisture; 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 for similar problems later

Material Drying silver streak misjudgment moisture distribution

Q

ABS silver streak non-moisture causes

A

The non-moisture causes of ABS silver streaks are in-depth diagnosis; gate, temperature and homogenization are adjustment directions; distinction ensures precise treatment.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
