When Western Consolidated Technologies was contracted to manufacture a series of back-up rings, our company was able to use a sequence of advanced machining processes to mass produce custom-built products that met with high client expectations. Using operations such as sintering, CNC Machining, turning and slicing, we were able to construct 42,800 back-up rings based upon a customer supplied, two-dimensional Auto CAD drawing.
Working with PTFE material, we first employed our advanced molding process to construct the general shape of the back-up rings, upholding a (±) 0.002 inch precision tolerance and a shrinkage allowance of 2.4-3.0 percent. Then, we turn, bore and slice each ring to match client specifications. Each part measured 1.241 inches in outer diameter, 1.003 inches in inner diameter and was .050 inches thick.
After each part was formed, we placed our back-up rings through a series of evaluations, including zyglo testing, a non-destructive inspection that looks for surface cracks, to ensure quality production. We also tested the overall part dimensions using calipers and measuring pins. Through our advanced machining procedures, we were able to manufacture a mass number of custom-built back-up rings that met with high customer satisfaction. |
