“Rafael Advanced Defense Systems, an Israeli pioneer in defense and cybernetic solutions, has purchased a vacuum titanium casting furnace from SECO/WARWICK for UPC Precision Castings. This is the first furnace of this type on the Israeli market. The technology solution (ALLOY VIM 40kg-400kW) is a single-chamber furnace, equipped with a hot (ceramic) and cold (copper, for CWI processes) crucible. In the first, ceramic crucible, melting processes of up to 40 kilograms of super alloys, mainly nickel-based, can be carried out. The copper crucible melts 10 kg of titanium at a time. The Alloy VIM furnace has a three-stage vacuum system, is equipped with a mechanical, Roots and diffusion pumps. The system allows the furnace to obtain high vacuum in the range of 10-5 mbar. The solution is also equipped with a mold heater. The entire project has been planned so that it can be equipped with additional accessories in the future. The solution has stub pipes where additional furnace equipment, such as an alloy additive feeder, can be installed in the future. It is undoubtedly a very versatile and efficient solution.

Blackening of ferrous metals has been known for ages. In XIX century America, blackening was used extensively for guns barrels to prevent corrosion and for enhancing their general look, reducing the light reflection and increase wear resistance properties.
There are three types of blackening in common use: Caustic Black Oxidizing, Room Temperature Blackening and Low-temperature Black Oxide.
Advanced Heat Treat Corp. (AHT) offers Caustic Black Oxidizing carried out at 290°F, which forms a black iron magnetite. The finish does satisfy the military specifications MIL-DTL13924 and AMS2485 [2]. The most common applications of this treatment are in the mechanical engineering and firearms industry for enhancing chemical, mechanical and optical properties of the components, see Fig. 2.
Nitriding/Nitrocarburizing with Blackening
UltraOx Hyper Optimizes Nitrogen and Carbon Content in Compound Zone
Structure of the near-surface layer of the components treated with one of the above technologies is quite complex and every detail of the layer is very precisely controlled by proper processing. Examples of those layers are shown in Fig. 4. Application of UltraOx and Hyper technologies are growing in demand since they can be used in the most challenging applications where the others anti-chafing and anti-friction technologies are not sufficiently good.

Recently we posted some photos of a very substantial vacuum furnace in the initial stages of construction at Ipsen in Rockford, IL, USA. Well perhaps substantial is an understatement, it is in fact a very large unit by anybody’standards. Since we mentioned this unit construction has progressed and the end user a North American captive heat treater is gearing up to receive the furnace-it is worth noting that this will not be the largest Ipsen vacuum furnace that the customer now has. To give you an idea about the size we will say that it will require 8-10 dedicated trucks to transport the furnace. Look for further updates on this system.

Just over a year ago the world’s largest commercial heat treater announced a brand new, state of the art facility in Syracuse, NY, USA (the original announcement is below). “The Monty Heat Treat News” has had the opportunity to see this plant and we can attest to the fact that it is by any standards a first class facility. What this means is that the Bodycote, Rochester, NY facility which is 90 miles away has been consolidated into the Syracuse location and is now closed. Always a shame to see such a long standing operation close however it makes absolute sense.
“FEBRUARY 2, 2021; Bodycote announces further expansion in North America; Bodycote, the world’s largest provider of heat treatments and specialist thermal processing services, is pleased to announce the opening of a new facility in Syracuse, New York, USA. The new Syracuse facility is the second new facility to be opened in North America in as many months, following on from the announcement of the opening of the new Elgin, Illinois facility in December 2020.
The Syracuse facility, encompassing 60,000 square feet of operating space, is now operational and offers a wide range of heat treatment processes. These include vacuum heat treating, atmospheric carburizing, low-pressure carburizing, carbonitriding, ferritic nitro carburizing, nitriding and aluminum heat treating. It is envisaged that the site will secure all major OEM approvals as well as Nadcap accreditation which it is already well on the way to achieving.
Stephen Harris, Bodycote Group Chief Executive, commented, “We are very pleased to announce the opening of another new facility in the USA, this time in Syracuse, New York. This investment demonstrates Bodycote’s continuing commitment to align resources to serve our customers across North America.”
This investment is part of Bodycote’s further expansion in the USA. Bodycote is committed to offering world-class heat treating services and is investing in improvements as part of an ongoing strategy to provide the best possiblecapabilities combined with superior quality. Bodycote’s geographic network is constantly evolving with growth targeted at serving both our customers current and future needs.”

“A global supplier of auto components recently ordered a new 2 bar vacuum furnace from SECO/WARWICK-this same company recently ordered 6 new tempering furnace from SECO for its machine tool manufacturing facility.
The international buyer’s automotive division placed an order for a single chamber high pressure quench horizontal vacuum furnace to increase its annealing production of fuel injector components. The new heat treating furnace will complement an existing SECO/VACUUM furnace in operation at that location since 2002. Because the new furnace is a nearly identical model, they share standard components and will reduce the necessary inventory of spare parts.
SECO/VACUUM’s Managing Director, Peter Zawistowski, said: “Once again, we have been rewarded for a good track record of performance and service support by this international automotive and machine tool components manufacturer. This furnace brings to 7 the number of vacuum heat treating systems we will have delivered to them in the past 3 years. It proves the familiar adage, ‘If we take care of you, you will take care of us.’ It is also very gratifying to know that their 20-year old furnace is still performing well with our support.”
The new furnace will have a chamber size of 36” x 36” x 48” deep and a load capacity of 3,300 lb. It is designed for a temperature uniformity of +/-10°F to meet the qualifications of CQI-9 and AMS2750F. The furnace will be equipped with SECO/WARWICK’s state-of-the-art control system, which includes a PLC and SECO/VACUUM SCADA systems. A battery-operated electric loader will also be provided to allow safe and convenient loading/unloading operations.”
