To compare with normal vacuum or hydrogen protective gas sintering furnace, This type of furnace can sinter and dewax cemented carbide or powder metallurgy product at one time in the same furnace, thereby saving power and reducing the oxidation of the sintered product Probability, so that the product quality is good, cost is low.
The Injectavac furnace was pioneered by Centorr Vacuum Industries in the early 1980's for the debind and sinter of parts containing 1st and 2nd stage MIM binders. It has been updated for today's MIM technology to process injection molded parts from wax/polymer binder removal through sintering in one continuous cycle.

NFPA 86D provides requirements for safeguarding against fire and explosion hazards in Class D furnaces that operate at above ambient temperatures to over 5000 degrees F (2760 degrees C), and at pressures normally below atmospheric to 10(to the minus 8) torr (1.33 x 10(to the minus 6) Pa).
older furnace or one that has been out of production for some time. This is because a vacuum furnace must normally be taken higher in temperature and soaked long enough to reach a steady-state heat loss condition. The cleanup temperature is typically 100 °F (56 °C) higher than the maximum operating temperature attained during a normal
Features. Designed for use with Blue M box furnace and control console systems; High temperature alloy for continuous use temperature of 1090 °C (1995 °F) O-ring seal between door plug and retort plate; Toggle clamps for positive seal; Heliarc-welded heavy gauge nickel alloy construction; Atmosphere sealed chamber
Gas Ballast Valves - One on each side of pump. Operators must check oil level and clarity weekly. Typical oil change - every 300 working hours or earlier if clarity decreases. Annually: Drain oil, remove this plate, clean oil sump, and replace exhaust valve springs and exhaust valve discs.
CLC Furnaces - - 48 East River St, Orange, MA 01364, USA email, Tel. +1 978-544-3984 CLC is an innovative and resourceful international leader in the design, manufacture, operation and reconstruction of high vacuum and controlled atmosphere heat treatment process systems.
Vacuum Oven. Vacuum oven is an ideal choice; where, samples are dried in absence of atmosphere (vacuum condition) or presence of inert atmosphere (Argon, Nitrogen, Clean Dry Air). A vacuum oven has two ports; Vacuum Port with needle valve to connect vacuum pump and another is Inert Gas Port with needle valve to connect with gas cylinder.
Manual furnace title, with variable speed electromechanical tilt option. Pumping System: 20" oil diffusion pump (18,000 liters/sec), stokes 1722 (1300/300 CFM) roughing and backing mechanical booster pump, and a 15 CFM hold pump complete with manifolding, vibration isolation joints and remotely operated vacuum valves.
Thermic Edge has a standard range of 2100c laboratory vacuum furnaces with graphite hot zones and inert gas injection for processing from atmospheric pressure to high vacuum, but we can also offer specially built or modified versions of the standard furnaces, with Graphite hot zones up to 3000c and Tungsten hot zones up to 2600c.
Desiccant tube has two-way action that permits the use of a smaller desiccant volume and better air contact with desiccant. atmosphere; vacuum valves provide means of vacuum atmosphere removal; vent port releases atmosphere from chamber. Built-in electrical outlet is included on all models for a vacuum pump.
Roots pump is a kind of rotary varactor vacuum pump, will only be used with backing pump with, in a wider range of pressure pumping speed, greatly . Vacuum freeze drying is a good way to current material dehydration, it can be freeze-dried material, frozen in advance, and then under the conditio.
Atmosphere Vacuum, Gas flow Infrared Gold Image Furnace System RHL-Ps / Pss series Applications • The Ps type has 40-mm wide reflective surfaces. • The Pss type has 20-mm wide reflective surfaces that allow high density lamp configurations. • Both the Ps type and the Pss type can heat a wide area by increasing the number of reflective
A pumping system is the heart of a vacuum furnace system. A variety of pumping system combinations are used in vacuum furnaces for evacuation of atmospheric pressure from the vacuum chamber to meet the level required for specific processes. The use of a suitable pumping system allows a vacuum furnace to deliver optimum performance.
the atmosphere) are stored under vacuum. Materials that readily oxidize are also often stored either under high vacuum, or in an inert atmosphere (nitrogen or argon gas) after the air has been removed from the storage vessel. Sample Problem: 3.2 List as many reactive elements or compounds that you know of which you would
Box-type controlled atmosphere furnace, also referred to as atmosphere furnace, is mainly used for sintering of metal, ceramic, powder metallurgy and other related materials, annealing furnace, tempering and the like.
Air Conditioning Vacuum Pump Operation. In the typical system, the vacuum pump is required to create a vacuum state of about 300 to 500 microns. An electronic vacuum gauge is needed to measure the level of vacuum in the system. Check the specifications of the vacuum pump and make sure that it is able to achieve the vacuum state as required by the manufacturers of the equipment.
rate check, pump the furnace down to ultimate pressure with the heat turned off and the furnace cold, at 70°F (20°C) or below. Record the vacuum level and the time. Next, isolate the furnace from the pumping system by closing the vacuum valve(s) to the chamber. Allow at least an hour to obtain an ac-curate leak-up rate. (This step is often
