Heat Treater Commissions Brazing Facility with 6 Vacuum Furnaces

/ AEROSPACE HEAT TREAT, BRAZING NEWS, FEATURED NEWS, MANUFACTURING HEAT TREAT, VACUUM FURNACES NEWS / Leave a Comment

Recently, Solar Atmospheres Eastern PA commissioned a new 25,000 square foot brazing facility aimed at high-volume, high-quality braze production. The facility features six vacuum furnaces dedicated to brazing, including an all-metal hot-zone furnace designed for brazing stainless steel to copper with silver and gold-based braze filler metal (BFM).

The heat treater specializes in the brazing of high-value components utilizing filler metals based on nickel, silver, gold, and copper. The new state-of-the-art production facility has 4,000 square feet of climate-controlled workspace, where technicians assemble and inspect parts, ranging from tiny capillary-tube manifolds to large land-based gas turbine blades. The operation incorporates increased capacity for helium leak testing and pre-braze tack welding of braze assemblies.

“With Nadcap accreditation and AS9100 registration, our new facility operates as one expects from the Solar brand,” states Chip Lahneman, general manager of Brazing at Solar. “The investment in our new facility demonstrates Solar’s commitment to meeting our customers brazing needs, now, and in the future.”

Heat Treater Expands with Vacuum Furnace

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

HTD Size-PR LogoA Swiss commercial heat treater ordered a vacuum furnace. A system will increase the production capacity of their nickel and silver brazing processes.

Vice President of Business of the Vacuum Furnace Segment
SECO/WARWICK

The SECO/WARWICK vacuum furnace helps with hardening larger size parts and significantly increases the efficiency of the current hardening plant. The furnace increases production. In the version ordered by the Swiss, a large working zone (36"X36"X48") with the potential to adjust to an oversized load utilizes the advantages of a round heating chamber.

“[With a] cooling capacity of 15 bar, it is possible to process parts that require very fast cooling . . . . Vector also allows the system to perform more difficult brazing processes with either nickel or silver," explains Maciej Korecki, vice president of the Vacuum Furnace Segment, at SECO/WARWICK Group. "This is our second installation with this partner. Previously, we delivered a solution from the SECO/WARWICK furnace family of a similar size, in a non-pressurized version."

2 Power Supplies Upgrade Heat Treat System

/ BRAZING NEWS, FEATURED NEWS, MANUFACTURING HEAT TREAT

HTD Size-PR LogoA Pennsylvania heat treat supplier recently shipped and commissioned two power supplies used in a continuous brazing furnace for a tool manufacturing company. The new power supplies, rated 125 kW supply and 100 kW, were designed as direct replacements for a pair of existing, obsolete power supplies that continuously failed.

Magnetic Specialties, Inc's power supplies reduce furnace downtime and provide tighter regulation of the furnace temperature which delivers more consistent quality of the braze parts. The brazing furnace has silicon carbide heating elements, which increase in resistance as they age. To compensate for this, the output transformers feature a tapped secondary winding. As the elements age, the client can select a higher output voltage range via the tap switch. The client will use the metering feedback to know when the tap needs to be changed.
