Graphite Rotors and Shafts
Max Graphite supplies graphite rotors and shafts to foundries, smelters, and metal treatment operations working in aluminum casting and broader non-ferrous melt purification, where dimensional consistency and coating integrity are direct process variables. We machine rotor and shaft assemblies across a full range of grades, geometries, and coating treatments from billet stock held in-house. Single-source supply covers prototype builds, ongoing foundry replenishment, and scheduled production volumes.
Engineered for Every Hour of the Aluminum Degassing Cycle
Graphite rotors and shafts sit at the core of rotating degassing systems — batch degassing units, in-line degassers, and ladle and crucible treatment stations — where the rotor shears inert gas into the melt to remove dissolved hydrogen and entrained oxide inclusions. The economics of this stage are unforgiving: a failed shaft stops the cast, and an under-performing rotor pulls hydrogen levels and yield in the wrong direction. Max Graphite manufactures rotor and shaft assemblies to drawing or to our reference geometries, finished with the coating system the application demands.
- Geometry built to your drawing — We machine rotors, shafts, and full rotor-and-shaft assemblies to specification, including custom impeller and vane profiles for defined gas-dispersion requirements.
- Grade selection matched to service life — Standard impregnated, isostatic, and high-density grades are available, so each build can be tuned to the temperature and abrasion profile of the unit.
- Coating systems applied in-house — Anti-oxidation and phosphate coating treatments are applied as part of the production process, with coverage and adhesion verified before dispatch.
- Foundry-paced supply schedules — Output covers one-off engineering samples through to standing replenishment orders, with stock programs available for repeat geometries.
- Engineering support on qualification and substitution — Our team builds drop-in replacements for existing degassing systems, working from OEM drawings or sample components.
