PA6 Product Conditioning Treatment
Problem Phenomenon
Products needed water soaking/conditioning before assembly, management was chaotic, and clips broke during dry-state assembly.
Cause Analysis
PA6 is brittle in dry state, and toughness recovers and dimensions stabilize after moisture absorption; conditioning can reach the use state in advance; direct 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 only on experience.
Solution
①Formulate a conditioning SOP (temperature/time/medium);②measure and assemble after conditioning;③record conditioning batches;④age precision parts after conditioning and measure again;⑤establish a conditioning management system.
Key Takeaway
Conditioning is the bridge for PA parts from 'dry state' to 'use state': dry-state nylon assembly = time bomb; conditioning SOP is a basic skill of nylon product factories and cannot be omitted.
