Working zone temperature: Max heating temp 1000C; rated heating temp range~ 850C; temp uniformity ±3C

Working zone heating control method: programmable auto control, process control, monitor, data collection and treatment by computer auto control.

Temperature control accuracy: constant temp zone ±3C

Thermocouple temperature measuring accuracy: <1C

One way process gas path matched, quality flow gauge adjust gas flow.

Q:Are you a factory?

A:Yes,We are China leading vacuum furnace manufacturer ,It was  formerly known as China National Vacuum Research Institute. Our factory is located in Shenyang city with Shanghai international sales department ,covering an area of over 10,000sq.m.We have powerful R&D team and manufacturing facility.

Q:What kind of vacuum furnaces do you have?

A:We make all kinds of vacuum furnaces, widely used in materials, IT, metallurgy ,machinery

and so on ,especially industrial vacuum furnaces: vacuum sintering furnace, vacuum brazing furnace, vacuum heat treatment furnace (hardening, quenching, annealing, tempering, nitriding, carburizing), vacuum induction melting furnace, laboratory vacuum furnace, induction furnace.

Q:Do you have customization or OEM service ?

A:We can provide the regular and standard model sizes, at the same time, we can customize furnaces as product ,work piece size, and temperature requirement .Meanwhile, we offer OEM service under the strict industrial standard.

Q:What kind of quality standard dose your furnace follow?

A:Firstly, we are ISO9001:2008 and CE certified factory, All the processes are strictly following the standard of the metallurgy process. In the factory, we have about 10 employees that work in the quality assurance department. We control the furnace quality in our factory as below:

1st step : Internal inspection (such as the supply chain management

,in-process quality control and final quality assurance which are executed by our QC engineer according to the technical contract)

2nd step: Pre-acceptance standard (buyer send engineers to check or entrust the third party to do in our factory,)

3rd step: Site acceptance(After the installation of vacuum furnace in user’s factory, we sign the reception report )

Q: Is it hard to operate &maintain?

A:Our furnace has the PLC controller and intelligent programmable temp. Controller, user can use touch screen to set curves, auto/manual switch interlock, auto &monitor system, it is easy to operate. We prepare enough spare parts for user and on line technical support.

Q:Can you serve customer oversea like installation and debugging ?

A:Yes,we can dispatch our engineer to your city for installation and debugging or other service. Meanwhile,we will offer relevant documents: The plan of equipment, Foundation condition graph, The layout of equipment, Electric control system schematic diagram, Main accessories operating instructions & qualification and on.

Q:How about training ?

A:Buyer sent operator to our factory to get trained about the furnace operation; Our engineers offer training in the users working site.

Q:What about payment terms?

A:L/C, T/T, and so on.

Q:How long is your furnace warranty period ?

A:Since passing the site acceptance ,it has 12 months warranty period .

Q:How to get quick quotation from us?

A:Please offer us the treating material, the work piece size, max. Temperature, heating zone dimension, vacuum degree and other special requirement. Then we can quote you ASAP.
