Forming Department

The forming department has 6 presses, the largest a 100 ton brake press. We do forming, joggling (hot & cold), checking & straightening, to support our machining operations.


Additional forming views including our 20 foot long freezer By using the freezer the natural aging cycle of aluminum is decreased so it can be in its most pliable condition for shaping into a specified configuration.

Holding aluminum at sub-zero temperatures is one of the many processes involved in the production of heat-treated extruded hardware.

To prepare aluminum for forming, Mulgrew Aircraft subcontracts the heat treating process to approved sources. Immediately after the extrusions are heat-treated, they are packed in dry ice and returned to Mulgrew Aircraft where they are kept in the freezer until they are needed on the forming press.

Heavy Extrusion Forming

This part goes on the 747 aircraft. Note the 9° bend on each end of this 13 foot long, 350 lb. aluminum L-shaped extrusion.

We do 100% of the machining and forming in house. After heat treat the parts are kept in our 20 foot freezer box so they remain pliable until we are ready to “finish form”each part.
