The TURBOVAC i/iX series of turbomolecular pumps are used where clean and stable high- and ultrahigh-vacuum is required, such as in heat treatment.

After much analysis, feedback from attendees and the uncertainty of COVID-19, the MTI Board of Trustees has approved transition to a virtual format for Furnaces North America 2020. Attendees will be able to experience the virtual exhibit hall for free. For those wanting to view the three live panel discussions and 35 technical sessions, FNA is offering a special for attendees of $199 for each of the first two registrants from a company and $49 for every person after that. To qualify, everyone must register on the same online registration form. 

Solar Atmospheres of Western PA is currently installing a new rapid quenching vacuum furnace that will ultimately eliminate the need for costly helium while increasing production throughput. Solar Manufacturing’s 10-bar vacuum furnace will mimic an older 2-bar furnace in size. However, this new 48-inch x 48-inch x 96-inch 10-bar furnace is equipped with a 600-HP blower designed motor, and it will outperform its older model by processing larger and heavier workloads with the use of nitrogen only.

SECO/WARWICK Group sold two vacuum furnaces for aerospace applications to one company in two locations: the United States and Singapore. The aerospace manufacturer has been a SECO/WARWICK customer in Europe for many years, but this is their first vacuum furnace ordered for a U.S. installation. The first furnace will be used for the heat treatment of exotic electrical steels. The high-pressure gas-quench vacuum furnace has a horizontal chamber with a workload size of 24 inches x 24 inches x 36 inches and a 1,300-pound hearth capacity. The second furnace will be used for annealing parts produced by 3D printing.

Solar Manufacturing has been commissioned to design and build a vacuum furnace for Magnetic Shields Ltd. of Kent, England. According to the companies, it will be one of the largest horizontal vacuum furnaces in the United Kingdom. The furnace, which is being built with a SolarVac Polaris control system, will be designed to accommodate loads up to 48 inches wide x 48 inches high x 96 inches deep with a maximum weight of 5,000 pounds. Operating at a vacuum level of 10^-5 Torr, it will be able to reach temperatures up to 2400°F (1315°C) and include a partial-pressure hydrogen gas process and an external quench system designed for negative pressure quenching.

Solar Atmospheres of Western PA (SAWPA) will install a 36-inch x 36-inch x 48-inch vacuum oil-quench (VOQ) furnace capable of safely quenching 2,000-pound loads without carbon-potential concerns. Designed and built by Solar Manufacturing, the furnace will be operational in early 2021. 

Reliable vacuum technology is essential in many metallurgical processes to produce high-quality products in a repeatable manner.

Youngstown Tool & Die, a manufacturer of aluminum extrusion dies based in Youngstown, Ohio, upgraded its in-house heat-treatment capabilities with two high-pressure gas-quench (HPGQ) vacuum furnaces from SECO/WARWICK. Youngstown Tool & Die, which has been in business since 1961, is moving into a larger facility to accommodate increased production needs. The new furnaces are part of the expansion project. According to the company, upgrading its existing atmosphere furnaces to HPGQ vacuum furnaces will significantly improve performance and increase throughput as it expands.

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.

Nitrex, a Novacap portfolio company and a global provider of fully integrated heat-treating solutions and technologies, unveiled a new corporate brand identity. A new logo will be adopted by all the Nitrex business units. For now, the names of the legal entities will not change so customers, suppliers and stakeholders can continue to use the existing names and addresses in all official communication. The new wordmark for United Process Controls leverages its well-known trade name, the UPC initials, in combination with the company’s best-known brand asset, Marathon Monitors, to form UPC-Marathon. G-M Enterprises, the newest addition to the Nitrex Turnkey Systems portfolio, traded its metallic graphic for a single-color wordmark using the same typeface as the other logos with the addition of the tagline, “A Nitrex Company.”
