Machining, Assembly, & Painting of Cast Iron Components

The project highlighted here exemplifies our ability to provide complete manufacturing services, performed to exact specifications, with tight lead times. This mixing mill was designed for use for a rubber and plastic mixing application. Components were delivered to us as a raw casting, the customer needed it to be fully machined, finished, and assembled.

The machining process required the use of our horizontal and vertical boring mills, which are all CNC equipped, as well as our radial arm drill and hydraulic press. Quality was maintained throughout the machining process with dimensional and visual inspections to maintain the required tolerances of +.001”/-.000”. The 10 caps and base frames, and the 20 bearing housings were then painted and shipped to the customer. The entire project was completed in less than 12 weeks.
