August 2002 - Nashua, NH -- Centorr Vacuum Industries announced it has expanded its
furnace offering for the Metal Injection Molding market with the introduction of a new
line of lower cost MIM-Vac™ custom metal hot zone furnaces, based on industry input concerning
features and capabilities.
Based on Centorr Vacuum Industries Workhorse® Metal Hot Zone de-sign, which has been sold
worldwide for the sintering of powdered metals, with over 1000 units in the field, the MIM-Vac has
a number of design improvements specific for use with MIM Feedstocks. These include Molybdenum
hot zones with integrally designed gas-plenum re-torts using our Sweepgas™ technology
for consistent gas flow dynamics over the parts, compact furnace layout and construction within
a steel framework enclosure for fast installation and aesthetics, a Dry mechanical pumping
system for clean and efficient handling of any binder, and the use of advanced Molybdenum
alloys in the hot zone and retort offering excellent creep resistance, higher recrystallization temperatures,
and longer life.
The new line of MIM-Vac™ furnaces offers a temperature uniformity under ± 5°C,
and operates in a partial pressures from 10 torr up to 1 atmosphere in Argon, Nitrogen, or
Hydrogen gas using mass flow controllers for completely automated control. It is available
with either a programmable controller interface or an easy-to-use HMI software package for
computer control. The new MIM-Vac™ is available in sizes from 4.5, 6.75, and 9 cubic foot.
Centorr Vacuum Industries is a high temperature vacuum / controlled atmosphere furnace manufacturer
with an installed base of over 6000 units worldwide. Their furnace offering ranges from
large commercial and production units with hot zones over 3m x 3m, to smaller Lab
and Research & Development furnaces for use at temperatures over 3000°C. They are
