European Aerospace Fastener Manufacturer to Add Vacuum Furnace

​”The plant producing highly advanced fasteners for the largest manufacturers in the aerospace industry, operating since the middle of the last century, ordered a VectorR vacuum furnace from SECO/WARWICK. The furnace will be delivered in a standard configuration and will meet the global aviation industry’s highest requirements.

The machine 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 Italian Partner is an innovator in the field of comprehensive fastening solutions. The Vector furnace will become part of a modern production plant, increasing not only its efficiency, but also guaranteeing thermally treated fasteners of the highest quality.

The furnace on order is a standard solution perfectly suited to aviation industry needs. Thanks to a very refined design without any additional modifications, the furnace will perform at high operating temperatures, up to 1300oC.

“This is SECO/WARWICK’s first contract with this Client. Our Vector furnace is perfectly suited to meet the fastener heat treatment challenges, while meeting all required aviation standards. The heating process for these materials 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. The customer required a very short cooling cycle, which is achieved with a 15 bar abs gas blower. These are the Vector vacuum furnace standard features. Due to the fact that we did not have to adapt it to the Italian manufacturer’s needs, it was also an economically beneficial purchase,” – says Maciej Korecki, Vice President of the Vacuum Furnace Segment at SECO/WARWICK.

The furnace on order is equipped with a dew point sensor for each of the gases. It is a system solving one of heat treatment’s very critical requirements, which is to control the quality/purity of the gas used during the process. Vector also features a partial pressure control system which helps prevent evaporation and sublimation of alloying elements from the load surface during the vacuum heat treatment.”
