Our History
Plastic Flow, LLC was established in 2002 as an outgrowth of Professor Mahesh Gupta's polymer processing research since 1987. Since its inception, Plastic Flow has marketed PELDOM and polyXtrue software packages and provided extrusion die design services to the plastic industry. The dedication and innovative skills of Professor Gupta and his graduate students has resulted in many of the world's first polymer processing simulations.
