Centorr Vacuum Industries Expands Its MIM Furnace Sales

This includes multiple furnaces to Dynacast International/US for its new MIM operation. Dynacast is a global manufacturer headquartered in Charlotte. In February 2013 Dynacast announced it would be adding MIM to its service offering. CVI has over 30 years of successful MIM furnace building experience. It’s new business is comprised of a smaller research-sized unit designed with a 2 cu ft (0,057 m³) hot zone (305 mm x 305 mm x 610 mm) and a larger production size unit at 9 cu ft (0,255 m³) with an (457 mm x 457 mm x 1220 mm) size hot zone. Other sizes are also available. The new MIM-Vac M (modular design) has a number of design improvements including advanced Molybdenum hot zones with “wide-flow” gas-plenum retorts using Sweepgas™ technology for consistent gas flow dynamics over all parts. It has a compact furnace layout with construction on a structural steel base for fast installation and easy hookup of all utilities, yet provides full access to major components for ease of maintenance, with no cumbersome panels to remove. A dry mechanical pumping system with CVI’s proprietary T/P(trap-over-pot) binder condensing trap provides clean and efficient handling of MIM binders with a second large trap after the vacuum pump for improved process cleanliness. The use of advanced molybdenum alloys in the hot zone and retort offers very good creep resistance, higher recrystallization temperatures, and longer service life. CVI’s removable and replaceable plenum sections keep retort replacement costs to a minimum. All systems include a flexible HMI design with CE certification. All MIM-Vac™ furnaces offer temperature uniformity better than +/- 5°C, and operate in partial pressures from 10 torr (1333,23 Pa) up to 750 torr (99991,78 Pa) of argon, nitrogen, or hydrogen gas using mass flow controllers for automated control.
