Delube/Dewax
CVI has specialized in process development for a variety of delube/dewax processes for carbides and ceramics. CVI process development encompasses a large effort for wax/polymer removal typical of injection-molded hard metals and ceramics. Tight pressure and gas flow control in tandem with effective event-based programming and sound retort design allow the entire load to view the same series of conditions as a function of time. This results in consistent downstream microstructures and repeatable carbon control. Depending upon the process requirements, a variety of wax and polymer condensation strategies have been utilized including vacuum delube condensation, Sweepgas™ condensation, and CVIs proprietary BRS™ technology.
