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

Glass fiber reinforced ABS floating fiber

A

GF-ABS floating fiber relies on 'temperature coating': heating up and slowing down lets the resin wrap the fibers; GF parts with high appearance requirements need process, texture, and grade cooperation, and are difficult to eradicate by machine adjustment alone.

Q

Persistent black specks after ABS material change

A

ABS material change black specks rely on 'SOP prevention' rather than post-adjustment: gradient temperature purging + disassembling and cleaning dead corners are standard actions; cross-switching with PVC is extremely risky, avoid it if possible.

Q

ABS production smoke and odor

A

ABS smoking=a clear signal of 'overheating': the temperature must be lowered and checked immediately, production cannot continue with a fault; smoke is both a quality problem and an occupational health problem, and shutdown management must be formed into an SOP.

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

Poor ABS painting/printing adhesion

A

90% of ABS poor adhesion is 'surface contamination': clean first before talking about paint; mold release agent is the number one suspect, lubricant precipitation is an invisible killer, and internal stress causes the coating to be cracked from the inside.

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

Narrow processing window of high heat resistant ABS

A

Special ABS must follow the grade's dedicated process: applying the general process to heat-resistant material results in either yellowing or brittleness; for narrow-window materials, temperature control precision and residence time must be managed even more strictly.

Q

Flame retardant ABS mold corrosion and precipitation

A

Flame retardant ABS='narrower processing window + stronger mold protection': temperature control, corrosion prevention, strong venting, and shutdown replacement—the four-piece set is indispensable; flame retardant materials are more demanding on equipment and process.

Q

ABS '2079851475616104458 chill marks

A

ABS chill marks=the mark of 'touching the cold surface in advance': raising the mold/plug temperature and delaying the contact timing can eliminate them; a typical temperature management problem, unrelated to the material.
