Solar Manufacturing successfully completed the installation and start-up of a large 100-ton-force vacuum hot press at Refrac Systems’ commercial and aerospace diffusion bonding operation in Chandler, Ariz. The press includes a 2-bar-gas fan-quench cooling system. The furnace hot zone was modified to contain a 100-ton-load hydraulic ram centered over the zone, which is configured to diffusion bond parts up to 36 inches wide x 48 inches long x 30 inches tall.
