Dynacast Orders MIM Furnaces
Centorr Vacuum Industries received an order for multiple MIM-Vac M furnaces from Dynacast International, a global manufacturer of metal components based in Charlotte, N.C. In February 2013, the company announced it was adding metal injection molding (MIM) to its service offering. The addition of MIM as a manufacturing process means that Dynacast will expand its ability to produce small, complex components using a wider variety of metals. The new MIM-Vac M (modular design) furnace 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, and it provides full access to major components for ease of maintenance.
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 excellent creep resistance, higher recrystallization temperatures and longer service life. CVI’s removable and replaceable plenum sections keep retort replacement costs to a minimum. All MIM-Vac™ furnaces offer temperature uniformity better than +/- 5°C and operate in partial pressures from 10 torr up to 750 torr of argon, nitrogen, or hydrogen gas using mass flow controllers for automated control.
Dynacast International operates 22 manufacturing facilities in 16 countries and has more than 3,000 employees. The company services industries including automotive, consumer electronics, hardware and computers.
