Q

ASA building material gutter deformation

A

The thermal deformation of ASA building materials is a joint problem of material boundary and structural design; fixing point design is more economical than changing materials; the actual roof temperature far exceeds air temperature.; After confirming effectiveness, solidify the parameters and pr...

Q

ASA automotive exterior part comprehensive failure

A

ASA automotive part failures are mostly multi-factor coupling; systematic investigation is better than single-point trial and error; combined condition testing is a reliable path for reproduction and verification.; After confirming effectiveness, solidify the parameters and practices into the wor...

Q

AEPDS processing temperature

A

AEPDS temperature management protects EPDM rubber; actual measurement prevents deviation; residence time control.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Q

ABS vent depth

A

ABS vent 0.025-0.05mm, shallow traps gas and deep causes flash; 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 subsequent similar problems

Q

ABS hopper bridging, unstable feeding

A

ABS 'if the feeding is unstable, no matter how accurate the process is, it is in vain': bridging and crushed material are common culprits; include the plasticizing time in monitoring, it often alarms before the product has problems.

Q

ABS granule hopper bridging

A

If the feeding is unstable, no matter how accurate the process is, it is in vain.

Q

ABS brittle cracking——metal insert stress

A

Insert parts need preheating, and sufficient interface wall thickness must be reserved.

Q

ABAK heat resistance balance

A

ABAK heat resistance is a function of the ratio; glass fiber reinforcement is the improvement means; actual measurement verification is more reliable than theoretical estimation.; After confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence

Q

ABAK processing temperature window

A

The ABAK temperature window is the intersection of the thermal properties of the two components; PA6-based is easier to process than PA66-based; actual measured temperature is the process benchmark.; After confirming effectiveness, fix the parameters and practices into the work instructions to pr...

Q

Fiber Fuzzing of Prepreg

A

This problem is a typical manifestation of fiber fuzzing of prepreg in compression molding. The core of the solution lies in the reasonable preheating of the material and the guarantee of fluidity, as well as the precise matching of mold temperature and molding pressure. It is recommended to make...
