PC Power Tool Housings
Problem Phenomenon
[Problem Phenomenon] Power tool housings require high impact resistance and heat resistance
Cause Analysis
PC or PC/ABS with high impact resistance and heat resistance is used for housings of drills and saw-type tools; verified under drop and temperature rise conditions; when troubleshooting on site, verify each item according to this mechanism one by one, and avoid blindly adjusting the machine based on experience alone
Solution
Select high-impact PC or alloy for tool housings; drop testing; temperature rise checking; after adjustment, take samples continuously to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes, so as to locate effective measures
Key Takeaway
PC tool housings are tough, withstanding both drops and temperature rise; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
