PCL '2079851475616104452 simulation data shortage
Fenómeno del problema
PCL '2079851475616104452 process simulation lacks material data, trial-and-error costs are high, and process development is slow.
Análisis de la causa
Commercial simulation software lacks PCL in material databases; thermal and rheological data are incomplete; simulation accuracy is limited; reliance on experimental verification; development cycle.；During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solución
①Collect literature data to build a material model; ②Experimentally verify simulation; ③Parameter sensitivity analysis; ④Data accumulation and sharing.；After adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Conclusión clave
The lack of PCL simulation data is the industry status quo; self-built models combined with experimental verification; data accumulation improves efficiency.；After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
