Q

ABS recycled material 20% upper limit

A

The 20% upper limit of ABS recycled material is performance assurance; crushing, drying and prevention and control both emphasized; verification ensures quality.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

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

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

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

Q

ABS water content causing product bubbles and brittleness

A

ABS water content = double blow of bubbles + brittleness: bubbles rely on venting and controlling volatilization, brittleness relies on thorough drying to prevent catalytic cracking; don't treat water content as only an appearance problem, its damage to molecular chains is the more fatal hidden d...

Q

ABS recycled material yellowing and brittleness

A

ABS regenerated material needs to 'control the ratio, control the thermal history, control the drying': the performance of multiple-times regenerated material drops off a cliff, don't use it for key parts; yellowing and brittleness are direct evidence that the regenerated material's thermal histo...

Q

Poor ABS ultrasonic welding

A

For ABS ultrasonic welding, 'clean the surface first, then adjust parameters, then check the structure': welding surface cleanliness is the premise, parameter matching is the core, and energy director design is the foundation; moisture causes cold welds, and drying is equally important.

Q

Surface defect amplification in ABS electroplating

A

The appearance of ABS electroplated parts is determined by the '2079851475616104452 front end: electroplating is an 'amplifier', and no '2079851475616104452 defect can be hidden; no mold release agent, strict drying, and stress control are the three iron rules of electroplating-grade ABS.

Q

ABS delamination and peeling

A

For ABS delamination, first check 'compatibility and contamination': mixing, color masterbatch carrier, and purging are the three major suspects, don't suspect the process first; delamination is an interface problem, and only by finding the pollution source can it be cured.

Q

ABS discoloration (yellowing)

A

ABS yellowing='a record of thermal history': controlling temperature, limiting time, and reducing shear simultaneously; the actual melt temperature is often higher than the setting, shear heat must be measured, and the drying step cannot be ignored either.
