Metal Composite Tooling
Touchstone is experienced in building a wide variety of metal tooling. With our own in-house metal fabrication facility and large-scale machining, Touchstone offers fast turn-around metal composite tooling production.
Touchstone produces tooling form aluminum, steel and Invar.
Most metallic aerospace composite tooling is manufactured from Invar 36, an alloy of iron and nickel, known for its low coefficient of thermal expansion that closely matches most carbon fiber composite parts.
Invar 42 is often used to produce ultra-high temperature tooling for polyimides. Touchstone also offers other solutions for the production of polyimide tools.
