Vacuum Carburizing Furnace

Therelek Engineers manufacturer vacuum carburizing furnaces or systems for various industries across different sectors, apart from other heat treating and co-related applications.Our vacuum carburizing furnaces cater to numerous industries like automotive, and defence.

Vacuum carburizing or LPC-Low Pressure Carburizing, carried out by Therelek’s vacuum carburizing furnaces  involves precise heating up of parts; followed by the addition of carburizing gases (acetylene/ hydro- carbon) under an absolute pressure of a few mbar. The steel absorbs the carbon and hence creates a high-end layer of hard metal or case.

Vacuum carburizing is a sophisticated and powerful carburizing process. When it is properly executed in well-controlled and maintained vacuum carburizing furnaces, the process offers excellent uniformity throughout the load and good lot-to-lot repeatability-typically better than can be achieved with conventional atmosphere-carburizing methods. The excellent uniformity and repeatability of the process are well recognized in the quality gearing and bearing fields where the process enables less grinding stock to be left on surfaces that require finish grinding to size or closer tolerances on those surfaces that are used as heat treated. Because of the precision with which process variables can be controlled and the tremendous flexibility of vacuum furnaces, vacuum carburizing or low pressure carburizing is well suited to processing both the new, more highly alloyed, high-performance grades of carburizing steels and the
current, moderately alloyed grades used commercially. Coupled with gas pressure quenching, tremendous opportunities in higher-performance, low-distortion gearing can be realized with the process.
