In a Mold Filling analysis, Shadow generates the proposed part geometry in either 2.5-D shell or 3-D solid tetrahedral elements. We model the complete runner system including the type (hot/cold), size and location. Then, as needed, we will modify the design to develop a more advantageous layout to optimize the manufacturing performance during the first stage of fill.

The results we typically evaluate are: Melt front pattern, fiber orientation, shear rate, shear stress, knit lines, gas entrapment, pressure distribution and temperature differential. By optimizing the manufacturing performance at this stage, Shadow will maximize your product’s quality and strength due to molding. These results are then coupled together with the Mold Packing analysis to produce valuable insight into your mold’s performance.

In a Mold Packing analysis, we identify and evaluate conditions found in the second stage of fill that can contribute to excessive warpage and tolerance inconsistencies. Examples of these results may include data pertaining to: excessive volumetric shrinkage problems, potential sink marks, premature gate freeze off, and poorly located gas traps.

I've worked with Rob at Shadow Polymers for over 15 years and every FEA, Moldex, & part design program has been run with confidence, courtesy, and most of all creative excellence. When the customer didn't know what to do next or what it all means to his design Rob explains it in terms needed for the customer to understand. I've been helping customers maximize their part designs and performance needs for 20 years and Rob has always been in the top 5 of my technology partners list. He will make a difference in your new part design or resolving processing issues too.
