Q

ASA injection speed 200mm/s

A

ASA 200mm/s is a high-speed process quantified reference; surface and weld lines benefit; matching prevents side effects.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Q

ASA injection speed high speed

A

ASA high-speed injection is officially recommended; surface and weld lines benefit doubly; low back pressure protects the material.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Q

ASA surface step defect

A

ASA step defect is a flow front stability problem; the smoothness of the speed curve is more important than absolute speed; defect position analysis is an effective diagnostic means.

Q

ASA injection pressure setting improper

A

The ASA pressure window has a clear supplier guidance range; timely switching between injection and holding pressure is a key action; parameter solidification relies on objective indicators such as weighing.; After confirming effectiveness, solidify the parameters and practices into the work inst...

Q

ASA poor venting trapped air

A

ASA high-speed process and venting capacity are bound conditions; solve venting first, then enjoy the surface and weld line benefits brought by high speed; venting design is checked according to high-speed filling.

Q

ASA weld line visible and low strength

A

ASA weld line governance counter-conventionally requires high-speed filling; weld lines on dark parts can only be relocated and are hard to eliminate; high speed must be matched with good venting.; After confirming effectiveness, fix the parameters and practices into the work instruction to preve...

Q

ASA chevron surface defect

A

ASA chevron defect is a rheological instability problem rather than a conventional process defect; the three elements of shear strain, stress, and friction are the governance direction; academic mechanism guides parameter adjustment more efficiently.

Q

ASA rubber particle orientation blooming

A

The essence of ASA surface blooming is rubber phase orientation; moderate injection speed is an official recommendation rather than conservative; the balance point between high speed and surface quality needs to be determined by mold trial.

Q

AEPDS surface quality

A

AEPDS surface quality needs fine process management; rubber phase is the material factor; inspection ensures consistency.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Q

ABS glass fiber exposure

A

For ABS floating fiber raise temperature, speed, and pressure, polishing assists; 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
