Workhorse AM

The Sintervac AM™ line of vacuum and controlled atmosphere furnaces is Centorr’s newest offering for the growing market for binder-jetted 3D printed and Additive Manufactured parts.

Originally designed and developed in the early 1970’s for the debinding and sintering of Tungsten Carbide materials with wax or PEG binder systems, the Sintervac AM™ takes this heritage and improves on the proprietary Sweepgas™ binder removal system offering a furnace that can debind in both partial pressures or in positive pressures of Argon, Nitrogen, or Forming Gas depending on the customer’s choice of binders.

The MIM-Vac M™ is Centorr/Vacuum Industries latest offering in its line of custom-engineered high temperature vacuum / controlled atmosphere furnaces 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 20 years of experience in MIM technology and over 40 years debinding and sintering PM parts. The core design is based on Centorr/Vacuum Industries Workhorse® Metal Hot Zone furnaces, which have been sold worldwide for the sintering of powdered metals, and the binder removal technology of Sintervac® units developed for the Tungsten Carbide industry (with over 1000 in use worldwide). The MIM-Vac™'M' 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.
