Our History

InVac Systems, Inc. was opened in 2003 after the closing of HD Special Products, Inc. and the retirement of its founder, Bob Higuera.  HD Special products had been designing and retrofitting vacuum end cap flanges since 1982.  HD's client base and flange portfolio has stretched from the US to Europe, and Asia.  HD was the original supplier of vacuum end cap flanges to most all OEM's including SVG/Thermco, MRL, and Expertech.  This knowledge and client base has been passed down and complimented with state of the art CAD expertise, extensive metals & plastic materials knowledge, quartz & silicon carbide design experience, and quality local Texan workmanship that can be unsurpassed.
