PVC Workshop Temperature
Problem Phenomenon
High workshop temperature in summer increases PVC processing degradation
Cause Analysis
High ambient temperature causes poor equipment heat dissipation, and the actual melt temperature is high; during on-site troubleshooting, verify item by item according to this mechanism to 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
Measure the actual melt temperature in summer and lower the setting; equipment ventilation and heat dissipation; workshop cooling; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
Key Takeaway
Ambient temperature changes require actual measurement and compensation; after confirming effectiveness, fix 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
