Custom Manufacturing of Casings and Liners for the Gas Turbine Industry

These custom gas turbine liners and casings were manufactured from a high temperature super alloy on Hi-Tek Manufacturing precision CNC vertical and horizontal turning centers. The process also utilized a 5 axis YAG laser, and a multi axis plunge/sinker EDM. Since 1980 Hi-Tek Manufacturing has produced over 100,000 of these components which vary in size from 1" to 60" in inside and outside diameter, and 15" to 40" in height.

For further details on these components or information on Hi-Tek wide array of precision CNC machining capabilities see the table below or contact Hi-Tek Manufacturing directly.
