Before and After Die Simulation

Extrusion Die Design Series – #3

Case Study:  Flow Simulation Helps Flea Collar Manufacturer


Customer’s die geometry was experiencing difficulty providing a uniform product. Customer noted some uneven product flow during extrusion.


Provide customer a design which would optimize flow and product uniformity.


Using our CFD flow simulation software, we first analyzed the customer’s existing die design and studied the flow of material through the die. Flow simulation revealed uneven flow velocities i.e., dissimilar product flow.

Original Die

New Die


Customer trialed the new design and successfully validated the findings from the flow simulation. Product uniformity had been vastly increased while product density was improved because of the dimensional changes to the die.
