The MIM-Vac™ is Centorr Vacuum Industries latest offering in its line of custom-engineered high temperature vacuum / controlled atmosphere furnaces and is designed specifically for the Metal Injection Molding Market.
Following the success of its graphite hot zone Injectavac™ which CVI pioneered in the early 1980's for the debind and sinter of parts containing 1st and 2nd stage MIM binders, today's MIM-Vac™ furnaces are the result of more than 10 years of experience in MIM technology and over 25 years debinding and sintering PM parts.
The MIM-Vac™ is designed primarily for 2nd stage binder removal and sintering, and has a number of design improvements specific for use with MIM Feedstocks. Tight partial pressure control and even gas flow in conjunction with effective event-based programming and sound retort design allows the entire load to view the same series of conditions as a function of time. This results in consistent microstructures and repeatable carbon control.
Depending on the customer's process requirements, a variety of wax and polymer condensation strategies have been developed, including vacuum delube/condensation; Sweepgas™; Injectavac™ BRS™; MIM-Vac™ BRS™; and Thermal Incineration.
Our revolutionary new gas-plenum retort has rows of perforations allowing even gas flow across all the work trays and uses Alumina ceramic support members for ease of construction and replacement. The work grid assembly also incorporates Alumina ceramic as tray supports for reduced metal-to-metal contact resulting in less sticking. The grid assembly is removable for production loading outside the unit and can be inserted into the chamber by load truck, eliminating timely hand loading of individual trays.
Centorr/Vacuum Industries' manufacturing facilities have been repeatedly expanded and now include a group of integrated shops staffed and equipped for machining, metal forming, fabricating, electro-mechanical assembling, and operational testing of complete furnace and related processing systems. Centorr/Vacuum Industries' Applied Technology Center is staffed with a graduate ceramic engineer and technician. The lab is equipped with five high-temperature furnaces, and various metallographic support equipment to permit analysis and evaluation of a client's process requirements.
