Low Pressure Vacuum Carburizing Furnace

Low Pressure Carburizing Vacuum Furnaces

Low Pressure Carburizing (LPC)

Low Pressure Carburizing (LPC) is a specialized, highly technical process pioneered by Solar Atmospheres designed to increase fatigue life and improve wear properties of your parts.  The case hardened surface is supported by a ductile, shock-absorbing core capable of withstanding high load bearing applications. LPC produces a uniform, high-quality case with minimized distortion and absence of Intergranular Oxidation (IGO), reducing or eliminating expensive post heat treating machining operations.

Solar Manufacturing offers the LPC capabilities on the Internal Quench Series model lines.  This furnace is a horizontal front loading, internal quench, low pressure carburizing furnace generally designed for high production commercial and captive heat treating shops. It is a high-temperature, batch type, vacuum furnace with electric resistance heating elements also capable of performing additional vacuum heat treat processes other than LPC alone.  The Internal Quench series is capable of quench pressures of up to 20 Bar (285 PSIG), which allows the furnace to carburize and harden in the same cycle.
