Mainstream Engineering of Rockledge, Fla., installed a controlled-atmosphere aluminum brazing (CAB) system designed and built by SECO/WARWICK. The system, which will be used in the manufacture of advanced heat exchangers and cold plates for military and commercial applications, allows Mainstream to braze a wide assortment of very large cold plates and heat exchangers using a variety of aluminum alloys. Bringing the CAB system in-house will improve quality by providing process control of all variables and lower lead times.
SECO/WARWICK’s universal batch CAB line offers versatility through its ability to braze products in both horizontal and vertical orientations. It provides tight temperature uniformity and atmosphere integrity, and it can be used as a batch R&D line for periodic production or as a production line working 24/7. It also has faster heat-up rate abilities, which will allow braze temperatures for trials to be prepared within hours instead of full shifts.
