ABS power tool housing
Problem Phenomenon
[Problem phenomenon] Power tool housings need high impact resistance and heat resistance
Cause Analysis
ABS has high impact resistance and good moldability, used for housings of electric drills and saws; heat-resistant grades cover temperature rise conditions; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based solely on experience
Solution
Tool housings select high impact or heat-resistant ABS; drop test verification; temperature rise verification; 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 tool housings are durable, withstanding both drops and temperature rise; 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
