Mallory Industries, Inc.

United States

Used to accommodate various electronics, the control housing shown was manufactured by Mallory Industries, Inc for a client from the aerospace industry. Our high speed milling machinery, which held tolerances as close as .0002", formed 30 of these components from solid-stock, AMS 4027 aluminum plate material. Once completed, the housings measured 12.360" x 9.350" x 2.000", and possessed a smooth, 32 RMS surface finish. These products featured helicoils, in addition to chemical film which fulfilled MIL-DTL-5541 specifications. They also satisfied UTC ASQR and various Hamilton Sundstrand standards, as well as our customer's high expectations for both performance and quality.

The component pictured was manufactured by Mallory Industries, Inc to be used within a helicopter application. Using our CNC turning and 3-axis CNC high speed milling machinery, which meets ultra-tight tolerances as close as .00025", we produced this part from 7075-T7351 aluminum material to measure precisely 10.75" x 9.68" in length and width, with a thickness of 2.5". The part also possessed a smooth, 32 RMS surface finish. The finished helicopter component featured bearing bores and journals, a hole true position tolerance of .001", and 3-D milling capabilities. Fulfilling Sikorsky specifications, we produced 50 of these parts for the aerospace industry, satisfying all client expectations for quality. (click on thumbnail to enlarge)

Recently, a client from the aerospace industry contracted Mallory Industries, Inc to produce 10 aluminum centrifugal pump impellers. These parts are used as components of a fuel pump. We combined our 2-axis CNC turning capabilities with our 3-axis CNC high-speed milling technology to produce these parts. We also performed wire EDM to create the intricate keyways. During the production of these impellers, our advanced machinery met ultra-precision tolerances as close as .00025" for all diameters, with a squareness tolerance of .0005". The finished parts measured 5" in diameter and .7" in material thickness, and possessed a smooth, 32 RMS surface finish. Fulfilling both Woodward specific standards and client specifications, each component featured .5" tall vanes, and a profile of .005". The impellers were also able to spin at speeds of 14, 000 RPM. By combining our advanced wire EDM and CNC machining technology, Mallory Industries was able to produce 10 precision centrifugal pump impellers for the aerospace industry that satisfied all of our client's requirements for quality, design, and performance.
