ASA Shrinkage Rate Management
문제 현상
ASA shrinkage rate 0.4-0.7% is low, post-shrinkage negligible, mold design.
원인 분석
ASA typical shrinkage rate 0.4-0.7%; post-shrinkage negligible; amorphous material; dimensional stability; mold design compensation; process influence.; during on-site troubleshooting, verify item by item according to this mechanism, avoid blindly adjusting the machine based only on experience
해결 방법
①Mold designed at 0.4-0.7%; ②post-shrinkage ignored; ③dimensional stability utilization; ④process stability; ⑤actual measurement verification.; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
핵심 요약
ASA low shrinkage and negligible post-shrinkage are dimensional advantages; mold design precise; verification ensures accuracy.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
