Proper control of distortion has become even more important in new powertrain designs. To answer the
demand for fuel-efficient vehicles, modern transmissions are built much lighter, therefore the components of
the transmission exhibit less wall thickness which makes them more sensitive to distortion. Distorted gear
components can create noise in the transmission, require post heat treat machining processes and may even
create problems during transmission assembly.
By applying the technology of Low Pressure Carburizing (LPC) and High Pressure Gas Quenching (HPGQ),
the distortion caused by heat treatment can be significantly reduced. This technology has been successfully
established in serial production for many different gear applications.
