Advantages of low pressure carburizing and high pressure gas quenching technology in manufacturing

摘要

With the many advances that have taken place to improve quality in the gear industry, it is only logical that heat treat services would have to evolve to meet the increased demands of precision gear manufacturers.For decades gear manufacturers used atmosphere furnaces with integral oil quenches for the case hardening process.In recent years Low pressure carburizing (LPC) and High pressure gas quenching (HPGQ) have become a preferred technology for fuel injection components and for the latest generation of transmissions, such as double clutch transmissions or 6/8 speed automatic transmissions. Gear manufactures participates on the advantages of the integrated production with low pressure carburizing furnaces. These advantages will be explained in followed article and shows that heat treatment is part of the entire manufacturing chain.
