The Quicklock Leaching Autoclave is also called core leaching machine, it is a system for removal of ceramic cores from aerofoils by means of eroding them away via a chemical process. It is important to remember that the Leaching Autoclave contains hot pressurized caustic when operating and is fitted with a number of safety interlocks which ensure that it operates safely.

The devices are arranged to fail to a safe condition. Whilst little routine maintenance is required it is important that the safety devices are checked on a regular basis.
