Request Expert

Have a total of 33 years industrial experience in Process Development related activities including Start-up and Manufacturing support. The last 22 years were focused on Compounding Processes. Have 4 US Patents re Reactive Extrusion. Along with Dr. Christian Maier co-authored the Hanser book UNDERSTANDING COMPOUNDING.

Have Specialized in Twin Screw Extruder Compounding and Reactive Extrusion Process Development from bench scale to world class production facilities including Toll Manufacturing. Process Control, Feed systems including preblending, Screw Design, and isolation of the compounded product are integral to this.

As a consultant for a Venture Capital Company, he has scaled up a complex Compounding Process including a Reactive Operation form a bench scale through OEM Vendor Trials to four commercial toll manufacturing lines.Scoped, Designed, worked with Bids, and supported start-up of a Bench Scale Leistritz TSE Research Facility at WVU.

Expert may consult nationally and internationally, and is also local to the following cities: Columbus, Ohio - Charleston, West Virginia - Huntington, West Virginia
