Q

ASA surface scratches

A

Scratch prevention and control of ASA high-gloss parts runs through the whole chain from production to assembly; hard coating is an effective means to improve scratch resistance; quantified acceptance standards avoid disputes.; After confirming effectiveness, solidify the parameters and practices...

Q

ASA demolding deformation

A

The dual mold temperature independent compensation for ASA demolding deformation is a practical technique recommended by the material supplier; fine temperature adjustment in the deformation direction is more precise than large process changes; ejection system balance is the foundation.

Q

ASA improper mold temperature poor gloss

A

ASA gloss is the superposition of three elements: mold temperature, polishing, and temperature-speed; mold polishing investment for exterior parts cannot be saved; the contradiction between cycle and gloss is reconciled by water channel optimization.

Q

ASA thick wall sink mark

A

ASA sink mark governance emphasizes both holding pressure and structural design; rib thickness ratio is a design red line; multi-stage holding pressure resolves the contradiction between sink mark and flash.; After confirming effectiveness, fix the parameters and practices into the work instructi...

Q

ASA uneven haze

A

The governance of ASA uneven haze returns to temperature and shear uniformity; appearance judgment standard should quantify haze value; cavity surface consistency is the basic guarantee.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Molds & Tooling ASA; haze; surface; mold temperature; shear; uniformity

Q

ASA melt temperature too low poor filling

A

ASA low-temperature defects are opposite in direction to high-temperature degradation, requiring two-way balance; layered temperature control avoids local overheating while ensuring plasticization; each temperature adjustment should not exceed 10℃.

Molds & Tooling ASA; insufficient filling; flow mark; cold slug mark; melt temperature; layered temperature control

Q

AEPDS mold design

A

Replication quality is the key point of AEPDS mold design; temperature and surface are both important; maintenance ensures long-term.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Molds & Tooling AEPDS; mold design; temperature; polishing; replication; venting

Q

AEPDS warpage deformation

A

AEPDS warpage management focuses on stress and cooling; uniformity is the core; process and structure are both important.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Molds & Tooling AEPDS; warpage; stress; cooling; wall thickness; mold temperature

Q

ABS surface orange peel

A

ABS orange peel stabilize front plus high polishing; 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

Molds & Tooling orange peel high gloss front polishing

Q

ABS mold deposit

A

ABS mold deposit needs regular cleaning, venting is the key point; 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
