CWM and Aerosonic Take Flight with NADCA Award

Congratulations to the Chicago White Metal Casting and Aerosonic Engineering teams for winning yet another North American Die Casting Association (NADCA) award for design excellence in 2019!

NADCA Die Casting Submission

The NADCA Award for Design Excellence is a prestigious die cast engineering award which enlists a committee chosen by NADCA  to review hundreds of submissions from various die casters and then carefully select the best of the best in the industry.

Chicago White Metal and Aerosonic worked on an Aircraft Altimeter housing, which is a die cast housing that attaches to another cup-shaped housing, protecting the gears and mechanics of the altimeter.  The “serrated” edge of the circular part of the component works in conjunction with the gears, with all parts responding to the barometric pressure of the atmosphere.

Aircraft Altimeter housing

The design came to Chicago White Metal as a concept – this was a new part which was collaboratively designed by both engineering teams.

The high pressure die casting process was used to create a net shape product with the gears included in the as-cast design.  This process allowed Chicago White Metal to produce parts at a rate of 130 casting per hour, which is faster and therefore less costly than any other process that could have been chosen for this project.
