ABS water content causing product bubbles and brittleness

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...

ABS recycled material yellowing and brittleness

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...

Poor ABS ultrasonic welding

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.

Surface defect amplification in ABS electroplating

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.

ABS delamination and peeling

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.

ABS discoloration (yellowing)

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.
