Q

ABS back pressure 5-15MPa

A

The coordination of ABS back pressure and screw speed is plasticization quality; shear heat management protects the rubber phase; actual measurement prevents deviation.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Processing Machinery ABS; back pressure; 5-15MPa; screw; 40-70rpm; shear heat

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 mold temperature 50-80

A

The 50-80°C of ABS mold temperature and high-gloss 60-90°C are standards; the 60°C lower limit and 90°C upper limit are boundaries; balance optimizes quality and efficiency.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Molds & Tooling ABS; mold temperature; 50-80°C; high gloss; 60-90°C; stress

Q

ABS barrel temperature gradient

A

ABS barrel gradient is fine temperature control; nozzle slightly lower to prevent drooling; verification ensures plasticization quality.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Processing Machinery ABS; barrel temperature; gradient; nozzle; 200-230°C; drooling

Q

ABS melt temperature 230-270

A

The 280°C red line of ABS melt temperature is both safety and quality; grade differences must be confirmed; actual measurement prevents display errors.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Material Analysis ABS; melt temperature; 230-270°C; 280°C; grade; actual measurement

Q

ABS flame-retardant part drying protection

A

The drying temperature upper limit of ABS flame-retardant parts is additive protection; 75-80°C is the safe zone; verification ensures flame-retardant performance.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Material Drying ABS; flame-retardant part; drying; 75-80°C; additive; degradation

Q

ABS high-gloss part drying tightened

A

The tightened drying of ABS high-gloss parts is the quality guarantee; 4-6 hours and 0.05% are the standard; exposure management prevents secondary contamination.；after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Material Drying ABS；high-gloss part；drying；85℃；4-6 hours；0.05%

Q

ABS drying 0.02% red line

A

The 0.02% red line and 3-4 hours of ABS drying are the standard; excessive drying oxidation is the other extreme; verification and storage prevent recurrence.；after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Material Drying ABS；drying；0.02%；silver streak；80℃；3-4 hours

Q

ABS glass fiber orientation type warpage

A

GF-ABS orientation-type warpage is broken by 'gate design', not by hard pressing with cooling: once the warpage direction is fixed, you should go back and review the gate and orientation, rather than repeatedly trying mold temperatures.

Molds & Tooling ABS；glass fiber；orientation；anisotropy；warpage

Q

ABS nozzle drool and cold slug marks

A

ABS drool and cold slug marks often have the 'same source': for drool, first lower the nozzle temperature and add suck-back; cold slug marks rely on the cold slug well to catch the front cold material; both point to nozzle temperature and cold material management.

Molds & Tooling ABS；drool；nozzle；suck-back；cold slug mark
