 Press Releases

  • After completing an intensive three day audit, Solar Atmospheres Southeast is pleased to announce its addition to the Boeing approved processor listing.  The Greenville facility joins an exclusive group of suppliers in the thermal processing industry and will have an approved scope of processing that will include the following specifications:

    • BAC 5613 – Heat Treatment of Titanium and Titanium Alloys
    • BAC 5616 – Heat Treatment of Nickel-Base and Cobalt-Base Alloys
    • BAC 5619 – Heat Treatment of Corrosion Resistant Steel

    Steve Prout, President of Solar Atmospheres Southeast states: “We are proud to be a part of the Boeing supplier network and look forward to working with suppliers in the Southeast region in support of Boeing.   We are excited that once again we are able to offer the Southeast US another regional option for aerospace processing that did not exist previously.”

    With thermal processing in furnaces ranging from those suited for small lots and development cycles to a 6-1/2 foot diameter by 24 foot long vacuum chamber capable of processing up to 50,000 lb loads with a maximum temperature of 2400°F, Solar Atmospheres is backed by AS9100 and Nadcap quality systems to give our customers confidence that their product is being processed appropriately.

  • Solar Atmospheres of Western PA recently added a very unique piece of equipment to its fleet of furnaces – a brand new, state of the art all molybdenum hot zoned vacuum furnace.  The all stainless steel chamber with a 24” wide x 24” high x 36” deep hot zone rated at 2500°F is equipped with an oversized pumping system.  Unlike other vacuum furnaces, this pumping system has a series of isolation valves which concentrates the critical vacuum levels within the location that matters most – the vacuum chamber.  Hence, this furnace was built exclusively for the critical materials often encountered in the aerospace, medical, and semiconductor arenas that are sensitive to vacuum levels and the potential contact of carbon particles.  To enhance the unshielded processing of critical parts at vacuum levels lower than 5X10-6 Torr without any contamination, Solar Atmospheres will construct an environmentally controlled room surrounding this furnace.  The room will be temperature, humidity, and positive pressure controlled which will aid in eliminating water vapor, dust, and debris (FOD) concerns.  New and clean dedicated fixturing will be used exclusively for this furnace, never leaving the premises.

    Bob Hill, President of Solar Atmospheres of Western PA states: “This brand new furnace and environs will enable us to guarantee bright clean work while eliminating the safety hazard of handling razor sharp stainless steel foils.  Now that this furnace is fully operational, in 2017 we look forward to adding the MedAccred medical accreditation to our ever expanding list of approvals.  I would like to thank our sister company Solar Manufacturing for designing and constructing this outstanding, pristine furnace that will enable us to produce parts that will significantly add even more value to our customer’s operations.”
