Deformation of PS Products During Storage
Problem Phenomenon
Inventory products deform after storage.
Cause Analysis
Internal stress is released under temperature changes; stacking pressure also causes creep deformation of products.; During on-site troubleshooting, verify item by item according to this mechanism, avoiding blindly adjusting the machine based solely on experience
Solution
①Reduce molding internal stress; ②Control the storage environment; ③Standardize stacking; ④First in, first out.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
Storage deformation stems from stress and pressure; both environment and management must be emphasized.; After confirming effectiveness, solidify the parameters and practices into the work instructions to prevent recurrence; Include this case in the defect archive as a reference for troubleshooting similar problems in the future
