Wall Thickness Design of PS Products
Problem Phenomenon
Improper wall thickness design triggers a series of defects.
Cause Analysis
Sudden wall thickness changes in PS cause stress concentration and sink marks; too thin results in insufficient strength.; During on-site troubleshooting, verify item by item according to this mechanism, avoiding blindly adjusting the machine based solely on experience; This mechanism has been repeatedly verified by industry literature and should be confirmed first during troubleshooting
Solution
①Uniform wall thickness design; ②Gradual transitions; ③Design ribs in proportion; ④Use rounded corners.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
Structural design is the starting point of defect prevention; uniformity and gradual transition are the principles.; 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
