ABS and PC/ABS material selection comparison
Problem Phenomenon
[Problem phenomenon] Structural parts waver between ABS and PC/ABS, cost and performance hard to weigh
Cause Analysis
ABS has low cost and good processing but limited heat and impact resistance (about 80°C); PC/ABS improves heat and impact resistance by the 30°C level but costs more; determine the grade according to working temperature and impact requirements
Solution
Indoor room temperature low cost select ABS; heat and impact resistance requirements upgrade to PC/ABS; match according to HDT and impact; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
ABS versus PC/ABS, cost versus performance graded by temperature; 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
