Nitrex is set to start the fourth phase of expansion at its commercial heat-treating facility in Aurora, Ill. The project will add a fourth building that will house a new low-pressure carburizing (LPC) system and secondary heat-treating equipment. The ECM vacuum carburizing furnace with oil-quench capabilities will help meet growing demand from makers of high-end critical parts within the automotive, aerospace and tooling industries. The 20-bar dual-chamber furnace has a workload size of 40 inches long x 24 inches wide x 28 inches high (1,000 x 600 x 715 mm) and a load capacity of 1,500 pounds (680 kg).
SECO/WARWICK received an order for a three-chamber vacuum furnace from a global manufacturer of automotive components. It will be the first furnace utilizing low-pressure carburizing (LPC) technology for the Indian company. It was chosen to solve a problem with intergranular oxidation present in the company’s traditional atmosphere heat-treat furnaces. The LPC furnace will be dedicated to small and large gear, pinion and other types of automotive gears.
Over the past few decades, the low-pressure “vacuum” carburizing process has proven time and time again to produce superior part quality.

The use of vacuum technology for carburizing has always shown the most potential for improving the manufacturing process by reducing both processing time and the number of manufacturing steps required to produce a part.
SECO/VACUUM Technologies (SVT), a SECO/WARWICK Group division with headquarters in Meadville, Pa., will supply a dual-chamber vacuum oil-quench furnace to an aerospace equipment manufacturer. The company is bringing its low-pressure carburizing and hardening work in-house. The furnace uses one chamber for vacuum heat treatment and the second chamber for oil quenching.
Aero Gear, a manufacturer of gearbox assemblies for the global aerospace market, completed a 24,000-square-foot expansion of its Windsor, Conn., facility. The company’s processing is conducted within its climate-controlled, 69,000-square-foot facility and includes gear-processing capabilities such as low-pressure carburizing and hardening heat treatment, nondestructive testing, super finishing and balancing. The expansion included manufacturing space for several new programs.
The acceptance of low-pressure (vacuum) carburizing (LPC) technology in manufacturing is due in large part to the ease of recipe development and modification made possible by the use of simulators designed specifically for this purpose. Let's learn more.
Rex Heat Treat purchased a 15-bar Vector vacuum furnace from SECO/VACUUM Technologies for its commercial heat-treating facility in Lansdale, Pa. The company created a newly upgraded climate-controlled vacuum heat-treat bay to house the new furnace, which will be used for through-hardening, tool and die steel processing, high-temperature solution nitriding, annealing and vacuum tempering. The system is scheduled for delivery by the end of the first quarter.
