AS9100 AND ISO9001 CERTIFIED
Boyd Aerospace uses the latest technology to support our commitment to service and quality. Partnering with Tier 1 Forging Companies, whose capabilities are unmatched by shear size and scope, Boyd Aerospace is the trail blazing distribution company providing forge blanking and processes.
For closed die operations, part weight can range from 10 to 13,000 pounds.
For open die operations, weight can be as high as 50,000 pounds. Maximum length is 40 feet. Maximum width is 70 inches.
For large seamless rings up to 312 inches in outside diameter, the ring sizer provides tension stress relief. The maximum weight is 20,000 pounds. Maximum face height is 72 inches.
Following final forging, the product normally is heat treated to develop the internal properties in the metal. It is subsequently cleaned, using abrasive materials and chemicals to remove the outer surface layers. Following this, most products are partially machined and then inspected thoroughly for dimensional and metallurgical characteristics. The final product is shipped to the customer at this point.
An Ingot is upset forged in open dies under pressure into a flattened shape ("slab"). A hole is punched into the slab to permit the next operation, ring rolling. The slab is heated to forging temperature and placed over the internal roll of the rolling machine. At the same time, pressure is applied to the wall by the external roll as the ring rotates. This process produces a circular forging with a seamless cross-section.
The rings are then rough machined to a rectangular cross-section. Aluminum rings are cold sized (tension stress relieved) to reduce built up residual stresses. Rings are then heat treated and undergo a final rough machining, parting and inspections and tests prior to shipment. The customer then must fashion the part from the rectangular shape to suit his or her own specifications and needs.
