PA12 Product Conditioning Treatment
Problem Phenomenon
Insufficient toughness after product assembly.
Cause Analysis
PA12 has better toughness when containing a small amount of moisture; it is brittle in a completely dry state.; During on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based solely on experience; This mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
Solution
①Conditioning treatment of products to restore toughness; ②control conditioning conditions; ③verify toughness improvement; ④determine conditioning degree according to application.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
Conditioning is a standard post-treatment for nylon products; PA12 is also applicable.; 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 subsequent similar problems
