PA66 product conditioning
Problem Phenomenon
Brittle in dry state, snaps break during assembly.
Cause Analysis
Dry-state PA66 has the lowest toughness; conditioning restores toughness and stabilizes dimensions; dry-state assembly is a high-risk operation; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience.
Solution
①Develop conditioning SOP (temperature/time/medium); ②assemble and measure after conditioning; ③keep batch records for traceability; ④unify aging management (measurement/assembly timing); ⑤reasonably arrange production and assembly rhythm, reserving moisture absorption time.
Key Takeaway
PA66 'condition first, then assemble': dry-state nylon is a time bomb; conditioning is a basic skill of nylon product factories and cannot be omitted; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence.
