Problem Phenomenon
Large-capacity IBC tank leaks in the drop test
Cause Analysis
The drop impact of the IBC tank is large, and the corners and welds are weak points; 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
Strengthen the corner structure; optimize the '2079851475616104457 wall thickness distribution; perform drop verification according to the dangerous goods packaging standard; 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
IBC tanks are drop-verified according to the dangerous goods packaging standard; 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
