Hy-Grade Metal Products has been providing metal spun parts since 1918. Our experience and knowledge of the spinning process, combined with the use of CNC equipment, make us a leader in the industry.

This inlet cone is used in the HVAC units of rail cars. It is essentially an air flow director for the units fan. Using 1100 aluminum, these part were sheared, circled, spun and machined to tolerances of as low as +/-.005”. After fabrication, parts are powder coated according to PSU-433-01, with a Tiger Drylac 38/91020 anodize silver topcoat.

These inlet cones have outside diameter of 12.050”, an inside diameter of 7.990” and an overall height of 2.230”. A bolt circle is machined into the offset ring after forming. Parts are visually and dimensionally inspected during the process to insure a consistent finish and the rings are to spec. We will typically provide 40-50 of these items per run. Lead times are within 4 weeks.
