We have to make sure that through a detailed in-mold rheological study the influence of injection speed on pressure to mold the part is studied leading to derivation of optimal molding window. We have to look at critical aspects like measurement of mold surface temperature, melt temperature and reduce their uncertainty while using them as inputs in CAE. When replicating a complex multi-domain problem in CAE, we have to look holistically on the ways of representing the part, tool, material and machine as proper boundary conditions.

This enables the design team to take confident decisions during part, mold and process development reducing reworks, accelerating development time, and optimizing development cost.

This helped SABIC to predict injection pressures within 10% of actual value for the resins it evaluated

SABIC developed a systematic approach and detailed steps replicating actual molding scenario in CAE and improved characterization of resin’s viscosity.

The results from CAE simulation need to be accurate so that confident decisions may be taken on part, mold, machine, and process design.

This demands development of newer analytical methods, material models and CAE solver capabilities for accurate process simulation Recent industry trends indicate that injection-molding applications are increasingly becoming thinner with the use of highly filled resins on the rise.The materials data team uses cutting-edge material characterization labs, predictive engineering capabilities and part level testing to validate material data that is used for designing applications.
