Q

ABS flow mark

A

For ABS flow marks raise temperature and stabilize speed; 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

Injection Molding flow mark mold temperature injection speed multi-stage

Q

ABS flash

A

For ABS flash reduce pressure first, clamping and parting line checked afterward; 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

Injection Molding flash clamping parting line pressure

Q

ABS burnt multiple factors

A

ABS burnt has four factors, check venting, temperature, speed, and nozzle one by one; 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

Injection Molding burnt venting melt temperature nozzle

Q

ABS burnt marks at flow end

A

Speed and venting of ABS burnt are the adjustment directions; 10% steps are a fine method; the end is the key area.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Injection Molding ABS; burnt marks; end; trapped gas; speed; venting

Q

ABS multi-stage injection application

A

ABS multi-stage injection slow entry, fast middle, slow finish; 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 subsequent similar problems

Injection Molding multi-stage injection jetting burnt staging

Q

ABS holding pressure ratio to prevent sink marks

A

ABS holding pressure 50-70% compensates shrinkage, thick-wall time extension is the key; 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 subsequent similar ...

Injection Molding holding pressure sink mark shrinkage thick wall

Q

ABS injection pressure and wall thickness

A

ABS injection pressure 70-140MPa, value selected according to wall thickness; 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 subsequent similar problems

Injection Molding injection pressure wall thickness short shot flash

Q

ABS high-flow grade processing

A

The filling advantage of ABS high-flow grade requires flash management; pressure and mold both emphasized; optimization ensures quality.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Injection Molding ABS; high-flow grade; thin wall; filling; flash; mold

Q

ABS injection pressure 70-140

A

The medium-high range of ABS injection pressure and the holding pressure ratio are standards; compensating shrinkage ensures accuracy; balance prevents stress.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Injection Molding ABS; injection pressure; 70-140MPa; holding pressure; 50-70%; shrinkage

Q

ABS check ring wear causing alternating short shot/flash

A

For ABS alternating short shot and flash, suspect the check ring first: this is a typical fault signal of the metering system; only by stabilizing the cushion do the process parameters make sense, otherwise the more you adjust, the more chaotic it gets.
