Difference between mold flow analysis results and actual products needs optimization
문제 현상
Difference between mold flow analysis results and actual products needs optimization
원인 분석
Mold flow analysis parameters (viscosity model) do not match cellulose acetate butyrate actual behavior
Analysis did not consider the influence of cellulose acetate butyrate crystallization behavior on flow
After gate position analysis and optimization, weld lines still exist in reality
Holding analysis prediction inconsistent with actual shrinkage depressions
Analysis did not consider viscosity change of PA types after moisture absorption
해결 방법
Use cellulose acetate butyrate dedicated viscosity model parameters
Set analysis parameters considering crystallization behavior
Verify analysis results against actual products
Correct analysis parameters according to actual products
PA types need to consider viscosity at different moisture contents
핵심 요약
Mold flow analysis requires material-specific parameters
