PBT reinforced material equipment wear
Problem Phenomenon
Accelerated screw and mold wear.
Cause Analysis
Glass fiber abrasive action; long-term operation increases the gap.; when troubleshooting on site, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry data and should be confirmed first when troubleshooting
Solution
①Wear-resistant material configuration; ②regularly detect the gap; ③monitor dimensional trends; ④replace according to cycle.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
Reinforced material wear is a continuous cost; wear-resistant configuration plus monitoring.; 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
