Advantages of Vacuum Heat Treatment

Vacuum as "Protective Atmosphere"

• No toxic protective gases containing CO

• No health hazards in the work shop

• No danger of explosion or open flames

• No furnace conditioning

• Use of inert gases (nitrogen or helium)

• No CO2 emission

Vacuum Carburizing

• Use of various processes

• Use of different gases

• Shorter carburizing cycles than in conventional technology

• Higher carburizing temperatures offer potential to further reduce process time

• Small gas consumption l instead of m3

Gas Quenching Instead of Oil Quenching

• Clean, dry parts after hardening

• No washing machine - no disposal of washing water

• No maintenance of washing equipment

• No complicated washing water chemistry

• Save space

• Cost benefits

• Quenching intensity is controlled via gas pressure or gas velocity

• No vapor blankets during quenching

• Homogeneous quenching

• Reduced distortion

Surface Influences

• Free of surface oxidation

• No surface decarburization

• Bright, metallic, shiny parts 

Plant Operation / Installation / Maintenance

• No idling over the weekend

• No continuous gas consumption

• Short heat-up times

• Fast access to installed modules

• No fire detection or sprinkler system

• No open flames

• No flammable gas mixtures

• Cold-Wall Technology

• No gas emission

• Minimum energy loss

• No heat radiation to atmosphere

Auxiliary Equipment of Protective Gas Plants are no longer required, like:

• Fire safety equipment

• Sprinkler system

• Exhausts

• CO2 extinguisher for the oil bath

• Measuring CO concentration in the shop

• Smoke exhaust in the roof (automatic opening and closing)

• Oil-proof floor or tank

• Methanol storage

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.
