PVC Surface Roughness
Problem Phenomenon
PVC product surface is dull and rough
Cause Analysis
Poor plasticization or poor mold surface condition; PVC is sensitive to plasticization quality; 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
Ensure plasticization temperature; polish the mold surface; check melt uniformity; 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
For surface roughness, check plasticization first, then the mold surface; 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
