Recently, a North American heat treater acquired a used VFS HL50 external quench vacuum furnace at an auction in the Philadelphia area. The main objective of this purchase was to retrofit this older furnace with a newer hot zone and pumping technology that will help minimize and target the condensation of detrimental binders evaporating out of MIM injection molded parts.

Solar Atmospheres of Western PA's maintenance team was responsible for refurbishing the furnace to its current standard. Solar Manufacturing, led by owner and CEO William Jones, designed the technology and the apparatus needed to consolidate the binders into one central location, thus minimizing the cleaning downtime the staff was experiencing. This includes a completely new hot zone, a binder pumping port, and a second vacuum pump. The collaborative effort ensured both projects came together seamlessly.

By mid-October, the high production MIM sinter job will be fully transferred from current Solar vacuum furnaces to this dedicated and refurbished vacuum furnace. After multiple sintering runs, the company will then have the data to compare the downtime of a traditional vacuum furnace versus the newly designed debind/sinter furnace. Solar looks forward to providing the MIM world with this new, critical processing information.

Mercury Marine Launches Heat Treat Upgrades

September 1, 2021 / CARBURIZING NEWS, FEATURED NEWS, PARTS CLEANING NEWS, VACUUM FURNACES NEWS

Mercury Marine of Fond du Lac, Wisconsin, recently launched a plan to upgrade its heat-treating capabilities with a move to the low-pressure carburization and high-pressure gas quench system. The new plan incorporates completely automated vacuum heat treating systems.

In the partnership with ECM Technologies, the Nano vacuum heat treating system (pictured above) incorporates 20 bar nitrogen gas quenching along with low pressure carburizing (aka vacuum carburizing). The Nano will operate several different carburizing, hardening, and spheroidizing processes simultaneously.

This change marks a departure from Mercury’s traditional atmospheric carburization and oil quench system while benefiting from advantages that come with vacuum processing:

Applies vacuum heat treating in lieu of traditional atmosphere (elimination of intergranular oxidation & highly repeatable process with consistent results)
Employs preventive maintenance planning, remote system status access, and facility information systems integration
Relocates heat treat from a secondary location to the clean, controlled environment of the machining centers
Converts to small batch processing principles to maximize process efficiency
State-of-the-art growth with ECM’s advanced system automation and robot capability with load building and breakdown
Controls downstream operations by matching incoming dunnage with exiting workpieces
Takes advantage of vapor and vacuum-based pre-cleaning technology to remove multiple machining lubricants
Incorporates cryogenic and tempering processes within the automated system

The system uses all CFC workload fixtures and ECM’s advanced automation fixture tracking to maintain a precise cycle count to know fixture life. For Mercury, this significantly reduces energy consumption and process cost per piece. Additionally, the vacuum process takes their heat treatment to a near-zero emissions for drivetrain components processed within the system.

45′ Long Seamless Nickel Alloy Tubes Vacuum Heat Treated Successfully

August 6, 2021 / FEATURED NEWS, MANUFACTURING HEAT TREAT, VACUUM FURNACES NEWS

Michael Johnson
Sales Manager
Solar Atmospheres of Western PA

Solar Atmospheres of Western PA successfully vacuum heat treated what is reported to be the largest and longest load of nickel alloy tubing ever in a commercial vacuum furnace. The mission was to preserve the crucial elements of brightness and cleanliness of the 45-foot-long seamless tubing while meeting extremely stringent mechanical properties.

“We spent countless hours reviewing critical systems such as triplicate pumping systems and redundant hot zone controls for any unforeseeable event that might arise during the 100+ hour run,” stated Michael Johnson, sales director at Solar Atmospheres of Western PA. “We are also fortunate that we can rely on our furnace manufacturing division, Solar Manufacturing, for guidance should any issue arise. This successful run will ignite a production campaign for the next 5 years, once again boosting confidence that this 48 foot vacuum furnace will surpass our customers’ expectations.”

Editor’s Note:

We suspected that this is a significant heat treating accomplishment, so we asked industry consultant and expert Dan Herring for perspective. Here are the questions and his responses. The following is provided by Heat Treat Today and not Solar Atmospheres of Western PA.

HTT: In what industries might these tubes be used?

DH: Typical examples would include steam generator tubing in nuclear power plants, high temperature aircraft systems, the oil and gas extraction industry, and anywhere applications call for corrosion/pressure/temperature resistant tubes/pipe.

HTT: Is there anything special about processing nickel alloy tubing?

DH: Yes. In order to maximize corrosion resistance, one must keep the surfaces of the tubes as oxide-free as possible. Hence, the use of vacuum. Also, the long lengths of the pipe means fewer welded joints (fewer joints means a stronger pipe, and likely more resistant to corrosion).

HTT: Is this release noteworthy?

DH: It is absolutely noteworthy. This demonstrates size capability available in only a handful (if that many) heat treat shops IN THE WORLD.
