ASA Stress Cracking
문제 현상
【Problem Phenomenon】ASA products crack when contacting solvents or at assembly stress points
원인 분석
ASA solvent resistance is limited (ketone, ester, aromatic erosion), solvents induce cracking under stress state; assembly interference and internal stress superimpose and amplify risk; during on-site troubleshooting, verify item by item according to this mechanism, avoid blindly adjusting the machine based only on experience
해결 방법
Check solvents in the use environment; high-stress parts annealed to relieve stress; chemical contact occasions do immersion verification first; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
핵심 요약
ASA stress cracking look at solvent and stress superposition, annealing verification; after confirming effectiveness, fix 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
