HDPE hopper management
Problem Phenomenon
Black specks appear when the HDPE hopper is not cleaned for a long time
Cause Analysis
Material accumulated in the dead corners of the hopper is retained for a long time and oxidized; 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 during troubleshooting
Solution
Clean the hopper regularly; avoid long-term material storage; empty when changing material; 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
Regular hopper cleaning prevents dead corner oxidation; 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 future problems
