ABS medical housing
Problem Phenomenon
[Problem phenomenon] Medical device housings need impact resistance and disinfectant resistance
Cause Analysis
ABS is impact resistant with good surface and resistant to various cleaning agents; used for medical housings and device parts; specific medical-grade grades are compliant; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based solely on experience
Solution
Medical housings select medical-grade ABS; disinfectant resistance verification; flame retardancy according to safety regulations; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
Key Takeaway
ABS medical housings impact resistant and cleaning resistant, compliant grades available; 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
