Thanks to this sophisticated technology, itis easier to remove the most complex ceramic cores, as opposed to the basic leaching in bathtubs for a short period of time. It is possible to use cores with a minimum SiO2
amount of 80% for the leaching, due to the aggressive potassium hydroxide lye (KOH) with a concentration of 38–42 %.We can leach parts up to a maximum diameter of 500 mm and a maximum height of 460 mm, with a maximum running time of 3 days for one process. For standard and verified parts, the time requirements can be reduced by up to several hours.
The use of this device will provide greater efficiency, better thrust and economic efficiency of turbine operation, especially for those using complex parts with complex cavities that make cleaning very problematic, where the leaching technology is often the only option for meeting these demanding customer requirements.
This technology was developed as part of the project "Innovation of the production process of precision castings of hot parts of aircraft engines, stationary gas turbines and radial turbocharger wheels".

Effective removal of ceramic cores
We offer a quick ceramic core removal system using potassium hydroxide in a Quicklock leaching autoclave equipped with several safety mechanisms to ensure safe operation.
Reduced length of leaching cycles from days to hours
In comparison with leaching in classic tubs, the process is considerably accelerated, because the entire cycle using the autoclave only takes 6 hours.
