Aviation Industry Supplier Expands with HPGQ Furnace

/ AEROSPACE HEAT TREAT NEWS, VACUUM FURNACES NEWS

A screws and fasteners manufacturer for the aviation industry is expanding its heat treating operations with a vacuum furnace with high-pressure gas quenching (HPGQ) and high vacuum for multipurpose and dedicated applications. The vacuum’s heating chamber is 16x16x24 in (400x400x600 mm), a compact design that accommodates the company’s small in-house hardening plant while still being large enough to enable efficient heat treatment of multiple components at once.

The SECO/WARWICK furnace is designed with the ability to work on both nitrogen and argon and includes a round heating chamber with a temperature uniformity of +/-9oF (+/-5oC), and convection heating up to 1590°F (850°C). The Vector HV (high vacuum) furnace meets standards required in the heat treatment of components intended for the aviation industry; material heating processes require cleanliness (which is why an additional argon-partial pressure system was used) and a high heating temperature of 2192oF (1200oC).

“The Client required very short cooling times, which are possible with the use of a 15 bar abs gas blower,” said Maciej Korecki, vice president of the vacuum segment, SECO/WARWICK Group. “Our advantage is that it is a proven solution (our standard but adapted to the partner’s specific requirements). Vector offers wide personalization possibilities, which significantly reduces project costs and ensures faster implementation time.”

Aviation Industry Supplier Expands Vacuum Heat Treatment Capabilities

/ AEROSPACE HEAT TREAT NEWS, VACUUM FURNACES NEWS

A company that supplies metal injection molded components for the aviation industry has expanded its production capabilities with a vacuum furnace. This solution will increase the capacity to provide hardening process services while meeting aviation standards required by the industry.

President of the Management Board
SECO/WARWICK Group

The Vector® vacuum furnace will process materials using an additional argon hydrogen partial pressure system, providing heating at a high level: 2192˚F (1200˚C). This is SECO/WARWICK‘s second collaboration with the company, one of the largest manufacturers offering metal injection molding technology with manufacturing capabilities including vertical integration of finishing technologies such as nickel and trivalent chromium electroplating, vacuum heat treatment and seal hardening, as well as precision grinding and CNC machining with micron tolerances.

“This partner is a global brand which has shown their trust in us for the second time by ordering a vacuum furnace, which we will now be able to service locally and more comprehensively,” said Sławomir Woźniak, president of the management board, SECO/WARWICK Group.

The furnace’s pumping system enables vacuum processes to be carried out in medium and high ranges, thanks to the use of a very good pumping system, and incorporates three process gases: argon, nitrogen, and hydrogen.

Leak Detection Seminar Highlights Best Practices

/ MANUFACTURING HEAT TREAT NEWS, VACUUM PUMPS GAUGES VALVES NEWS

Retech Systems LLC welcomed participants to its Buffalo, NY, facility for a leak testing seminar last month, unveiling best practices and the basics of equipment on December 4-5, 2024. Vacuum technologies provider Busch Group co-hosted the event, which was open to employees and clients of both companies.

Retech Systems LLC, which manufacturers metallurgical furnaces, is a daughter company of SECO/WARWICK Group. Busch Group brands include Busch Vacuum Solutions, Pfeiffer Vacuum+Fab Solutions and centrotherm clean solutions.

Ron Ligthart from the Busch Group, a leak detection expert with over three decades of experience in the industry, presented the seminar on the first day of the event to Retech and other SECO/WARWICK employees. Attendees learned the basics of how a helium mass spectrometer leak detector works and best practices on the techniques for leak testing large vacuum systems. After a few hours of classroom-based material, students were able to put their knowledge to the test on a vacuum furnace on Retech’s shop floor using a Pfeiffer leak detector.

On day two, local Retech, Busch Group and Pfeiffer Vacuum clients were invited in for a similar activity. Overall, the event focus was on:

  • best practices for tracer gas leak testing
  • how to properly spray helium and identify leak locations
  • minimizing the time spent leak testing
  • connecting the leak detector to the ideal location and using features of the instrument (i.e. zeroing) correctly

“We had a great time partnering with Retech on this event,” said John McLaren of the Business Development – Leak Detection division at Pfeiffer Vacuum, Inc. “We’re always happy to share the knowledge we’ve gained and help customers improve their leak testing process.”

Aerospace Parts Manufacturer Upgrades Vacuum Heat Treating Capabilities

/ AEROSPACE HEAT TREAT NEWS, BRAZING NEWS, FEATURED NEWS, VACUUM FURNACES NEWS

A global manufacturer of aircraft parts has ordered a single-chamber vacuum furnace for brazing jet engine parts. The new equipment will replace a 30-year-old unit previously operating in its Poland-based plant.

The new Vector® vacuum furnace is being supplied by SECO/WARWICK, which also manufactured the retiring equipment. The upgrade is based on a standard Vector vacuum furnace with a working space of 900 x 900 x 1200 mm, with screen insulation and metal heating elements. The solution has been adapted to industry specific needs and can heat treat jet engine components, such as complex gears or main shafts.

“This unit is distinguished by the ability to carry out efficient and clean high vacuum processes thanks to the use of a molybdenum heating chamber and a very efficient pumping system. This ensures very high purity and the dynamics required for brazing processes. Another big advantage is the very good temperature uniformity in the molybdenum heating chamber and compliance with the strict requirements of industry standards such as AMS2750,” said Jędrzej Malinowski, sales manager, SECO/WARWICK Group.
