Vacuum Furnace for Jet Engine Components

A vertical vacuum furnace is heading to a company that provides repair and maintenance services for jet engines. The system has been designed to carry out clean brazing processes in high vacuum, ensuring protection of the treated part surfaces. The solution will be used to process jet engine components.

The system will improve production processes and significantly increase the commercial heat treater’s efficiency. "The vertical vacuum furnace is the answer to the challenges of annealing and brazing larger aviation components . . . the cooling system provides precision cooling rate control for the parts in process," explains Maciej Korecki, vice president of the Vacuum Segment at SECO/WARWICK Group, a heat treat technologies company with North American locations.

New Vacuum Furnace for Aerospace Fasteners

An aerospace fastener manufacturer, operating since the mid-1900s, ordered a vacuum furnace. The equipment will process self-locking nuts, nut plates, barrel nuts, stud nuts, spline nuts, clamp nuts, as well as a wide range of washers and flanges.

The furnace from SECO/WARWICK Group, a global furnace technologies company that has locations in North America, will meet the AMS2750G standard in the second class (II) including B-type instrumentation for the aviation industry. The addition will become part of a modern production plant, in Italy, and will perform at high operating temperatures, up to 23720F.

“The heating process for these materials [fasteners] require extraordinary purity, which is why the presence of two gases is important: argon – used for partial pressure, and nitrogen – used mainly in the cooling process,” commented Maciej Korecki, vice president of the Vacuum Segment at SECO/WARWICK Group. “The customer required a very short cooling cycle, which is achieved with a 15 bar abs gas blower.”

Heat Treat Furnace Shipped to Aerospace Fastener

A vacuum furnace recently shipped to a U.S.-based aerospace fastener manufacturer. The furnace will be primarily used to age-harden various fasteners of high strength alloys used in the aerospace industry.

This is the second Model HFL-5748-2IQ furnace for this manufacturer. Like the first furnace, the new furnace features a graphite insulated hot zone of 36” x 36” x 48” deep with a weight capacity of 5,000 lbs., a maximum operating temperature of 2400°F, and a 100 HP quench motor. The control system was customized to interface with the customer’s in-house automation system for recipe control and data acquisition.

“Our customer needed additional furnace capacity to keep up with demand,” commented Jason Davidson, regional sales manager, Solar Manufacturing.

Heat Treat Solution for MTU’s Jet Engine Repair Service

MTU Aero Engines AG will receive a vertical vacuum furnace with the purpose of bringing heat treat in-house. The bottom-loading and gas cooling furnace will be used to process components for civil aircraft jet engines.

SECO/WARWICK Group, a global furnace technologies company with locations in North America, will supply the Vector® vacuum furnace.  The equipment has an internal cooling gas blower as well as internal heat exchanger. The system is in accordance with the AMS2750G standard in the second class (II) including B-type instrumentation for the aviation industry.

The aerospace/MRO industry is facing a major challenge. Interrupted supply chains and the difficult geopolitical situation in Europe means that many AEROSPACE/MRO companies have to revise their existing development and optimization strategies,” says Maciej Korecki, vice president of the Vacuum Segment at SECO/WARWICK Group. “[MTU’s] bringing the heat treatment process in-house with the purchase of this vacuum furnace allows the company to fully control the production process.”

Heat Treater Commissions Brazing Facility with 6 Vacuum Furnaces

Recently, Solar Atmospheres Eastern PA commissioned a new 25,000 square foot brazing facility aimed at high-volume, high-quality braze production. The facility features six vacuum furnaces dedicated to brazing, including an all-metal hot-zone furnace designed for brazing stainless steel to copper with silver and gold-based braze filler metal (BFM).

The heat treater specializes in the brazing of high-value components utilizing filler metals based on nickel, silver, gold, and copper. The new state-of-the-art production facility has 4,000 square feet of climate-controlled workspace, where technicians assemble and inspect parts, ranging from tiny capillary-tube manifolds to large land-based gas turbine blades. The operation incorporates increased capacity for helium leak testing and pre-braze tack welding of braze assemblies.

“With Nadcap accreditation and AS9100 registration, our new facility operates as one expects from the Solar brand,” states Chip Lahneman, general manager of Brazing at Solar. “The investment in our new facility demonstrates Solar’s commitment to meeting our customers brazing needs, now, and in the future.”

SECO/WARWICK

A manufacturer has chosen a heat treat vertical vacuum furnace designed to perform low-pressure carburizing for the large structural elements (gearboxes) used in wind power plants.  

SECO/WARWICK Group, a manufacturer with North American locations, provided the furnace that combines two technologies: atmospheric and vacuum processing. This system provides: process purity, heating uniformity, and elimination of the oxidation effect at the grain boundary. The product solves the problem of high energy and process gas consumption by the partner’s old furnaces, and shortens the carburizing process.

"The Pit-LPC technology . . . increases the safety for users, because it does not involve explosive and flammable gases. LPC eliminates direct CO₂ emissions from the carburizing atmosphere,'" commented Maciej Korecki, vice president of the Vacuum Products Segment at SECO/WARWICK Group.
