The WHK Management Team


Robert R. Klingel, Jr., President

Rob literally grew up in the polymers business, working at TSE Industries, Inc. (TSE), a custom rubber and plastics manufacturer, owned by the Klingel family.  TSE was founded by Rob's grandparents, Walt & Helen Klingel, whose initials make up the name of WHK. After TSE acquired medical tubing and assembly company, Consolidated Polymer Technologies (CPT), Rob went to work there, learning all aspects of the business.

In January of 2007, TSE sold CPT to Saint-Gobain Performance Plastics.* Rob stayed on, serving as its Vice-President of Operations and Plant Manager. He handled the day-to-day operations of the C-Flex® Division*, including financial, extrusion, molding, and overmolding activities.
