Milling & Painting of an Aluminum Valve Cover for the Forklift Industry

With our capacity to provide full end-to-end contract manufacturing services, a client in the forklift industry chose Miller Precision Manufacturing Industries, Inc. to produce the aluminum valve cover pictured here. Having only two weeks to get the job done, we configured a special fixture to hold the workpiece to allow smooth operation and quick transition from part to part during a high speed, dual operation horizontal milling process. Inspection equipment right on the shop floor allowed us to make precise dimensional measurements while production was in progress. Parts were also pressure tested to confirm there were no leaks in the material

When completed, the valve covers measured 17.400" in length x 9.720" in width x 4.165" in height, and were accurate to within ± 0.0005". Other activities for this project included developing a proprietary paint process and packaging the components in special bags and containers. Within a very narrow time constraint, we machined, tested, finished, and packaged the 5,000 units in this order.
