Problem Phenomenon
[Problem Phenomenon] Medical device housings require disinfectant resistance, flame retardancy, and impact resistance
Cause Analysis
PC/ABS resists various disinfectants, has a full range of flame-retardant grades, and is impact-resistant and durable; used in housings such as monitors and infusion pumps; biocompatibility is evaluated by grade; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solution
Select disinfectant-resistant PC/ABS for medical housings; flame retardancy according to safety regulations; verify cleaning and disinfection cycles; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Key Takeaway
PC/ABS medical housings resist disinfectants, meeting flame retardancy and impact resistance standards; 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 in the future
