PBT product wear-resistant application
Problem Phenomenon
Service life of wear-resistant parts not up to standard.
Cause Analysis
PBT wear resistance is good but grade and process affect actual performance; degradation reduces wear resistance.; when troubleshooting on site, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solution
①Select wear-resistant grades; ②control processing heat history; ③conduct wear tests; ④evaluate lubrication modification.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
Wear-resistant applications give equal weight to material selection and process protection.; 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
