Dewaxing of rocket engine combustion chambers at the Ottobrunn Production Centre, Munich.


 Dewaxing

DewaxingDewaxing is an important process that we use during the production of combustion chamber cooling channels.

Cooling channels are milled into a copper liner of the combustion chamber. These channels are then filled with a conductive wax before being nickel plated. After plating, the wax is completely removed from the channels using cleaning machines especially developed for the purpose.
