Computer Simulation Helps Reduce Extrusion Cost by 50 Percent

Derby Cellular recently found it difficult to profitably produce an EPDM environmental seal for a complex geometry. The initial plan was to produce the part using a single-cavity die. As a result of the complex geometry, approximately 20 trials on the extrusion line would have been required at a total cost of about $16,000 for a single profile. Because the production rate of the single-cavity die was too low to compensate for the expense of operating the extrusion line, Derby Cellular decided to use computation fluid dynamics (CFD) to evaluate whether or not the part could be produced using a two-cavity die.
