Q

PCABS nozzle temperature

A

PCABS nozzle temperature matching is a quality detail; cold material and drool are both important; actual measurement ensures accuracy.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Processing Machinery PCABS；nozzle temperature；245-260℃；matching；cold material；drool

Q

PCABS injection pressure

A

The medium-high range of PCABS injection pressure is the filling guarantee; stress and mold safety are both important; fixing ensures stability.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Injection Molding PCABS；injection pressure；80-130MPa；viscosity；complex；stress

Q

PCABS mold temperature

A

Grade differences in PCABS mold temperature must be confirmed; high mold temperature is the quality choice; balance and optimize the cycle.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Molds & Tooling PCABS；mold temperature；60-100℃；surface；weld line；cycle

Q

PCABS barrel temperature gradient

A

PCABS barrel gradient is fine temperature control; each section has different functions; verification ensures plasticization quality.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Processing Machinery PCABS；barrel temperature；gradient；feed；nozzle；plasticization

Q

PCABS melt temperature window

A

The ratio dependence of PCABS melt temperature is a material characteristic; 300℃ is the degradation red line; actual measurement prevents display errors.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Molding Process PCABS；melt temperature；220-280℃；ratio；300℃；actual measurement

Q

PCABS drying temperature and time

A

Supplier differences in PCABS drying must be confirmed; dehumidifying dryers are standard equipment; moisture content verification is the final criterion.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Material Drying PCABS；drying；80-110℃；3-4 hours；dehumidification；dew point

Q

PCABS hydrolysis strength loss 50%

A

PCABS hydrolysis is the culprit of 50% strength loss; the 0.02% moisture content red line must be quantitatively verified; visual judgment of drying is a fatal error.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Material Drying PCABS；hydrolysis；strength loss；50%；0.02%；drying

Q

PC/ABS electronic housing application

A

Electronic housings rely on dual guarantee of material and process.; 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

Processing Machinery PC/ABS；electronic housing；thin wall；precision；grade；inspection

Q

PC/ABS automotive interior application

A

Automotive applications require material selection and verification according to OEM standards.; 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 pro...

Processing Machinery PC/ABS；automotive interior；surface；VOC；grade；standard

Q

PC/ABS molding cycle

A

Cycle optimization is data supported.; 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

Processing Machinery PC/ABS；cycle；cooling；optimization；water channel；monitoring
