ABS modification direction
Problem Phenomenon
[Problem phenomenon] Standard ABS performance insufficient, how to choose the modification direction
Cause Analysis
ABS can be glass fiber reinforced (rigidity), flame-retardant modified (safety regulations), heat-resistant modified (HDT improvement), electroplating grade (adhesion), high flow (thin wall), etc.; select the direction according to the shortcoming
Solution
Rigidity select glass fiber, safety regulations select flame retardant, heat resistance select heat-resistant grade, thin wall select high flow; coordinate with the material supplier; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
ABS modification menu is rich, select the direction according to the shortcoming; 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
