Vulcan Delube System

Abbott Furnace Vulcan Delube System for Sintering Furnaces


Lubricant removal continues to be one of the most challenging steps in the production of powder metal components. As compaction technology continues to push green densities to higher levels, the removal of the lubricant from the compact becomes even more difficult.

The new Vulcan Delube System, developed by Abbott Furnace Company, addresses this need. Through precise atmosphere and temperature control, the powder metal compact is placed in the optimal environment for the extraction of the lubricants.

Existing technology is very sensitive to product size, belt loading, and lubricant content. Weight loss studies have demonstrated that the Vulcan Delube System is built with enough flexibility to allow the atmosphere and thermal profile to be adjusted to prevent the oxidation of light loads and small parts; as well as the ability to remove large amounts of lubricant from heavy loads and large products.


A Review of Lubricant Removal Systems and the Latest Technology

Whether a component is produced through binder-jet additive manufacturing, metal injection molding, or conventional press and sintering, lubricant removal continues to be one of the most common issues in sintering.  As with all technologies, new forming techniques have resulted in the development of new lubricants.  The result is the need for even more understanding and process development in lubricant removal.   A review of the “old rules of thumb”, current solutions, and where the lubricant removal technology is headed will help to lay out a roadmap for dealing with this issue today and into the future.
