PBT electrical application tracking
Problem Phenomenon
Insulation performance of electrical products not up to standard.
Cause Analysis
Improper grade selection or surface condition affects electrical performance; PBT electrical properties are good but special grades must be selected.; when troubleshooting on site, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solution
①Select electrical-grade PBT grades; ②control surface quality; ③test and verify according to standards; ④evaluate additive influence.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
Select special grades for electrical applications; standard testing is the release basis.; after confirming effectiveness, solidify 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
