What is e-Ion Plasma™? - Features of Plasma (Brochure) - Extremely Wide Area Plasma (with LIP)

The unique e-Ion Plasma™ allows for unique applications of Ions, Electrons, Radiation and Hot Gases. The e-Ion Plasma™  produces a CleanElectricFlame™. This thermal plasma technology platform offers clean-green technology that can use just electricity and air, leaving behind no residues.  It is a new alternative to electron, laser, induction, and other Rapid Thermal Process heating methods. MHI's e-Ion Plasma™ uses less energy, produces less noise and is safer than traditional heating methods. All e-Ion Plasma™ devices feature integrated patented technologies developed by MHI. Other features

of e-Ion Plasma™ include: Highly efficient low power consumption, no water cooling, no ground electrode required and very small foot print. 

Plasma polymerization of many unique polymers and blends and their surface deposits remain unexplored with this new method.

Live Demo


Rapid Sintering of 3-D Printed Products.  Use e-ion enhanced systems to rapidly sinter, hardface and clean. Cut time from 36 hours to few minutes in some cases.

Systems available for rapid sintering of platics, metals, ceramics and composities. 

Please Contact MHI to schedule a live demonstration on your part.  Demonstrations can be given live on SKYPE or equivalent. 

Simply contact us.  Send us your part and let us demonstrate the results live.

Helpful recomendations:  Consider Zapper and Magnifiers for metals and ceramic.  Use e-ion LIP or OAB for polymer 3D sintering.

Yes, even titanium can be sintered within minutes from start to finish.  Extremely shiny parts even for copper or tungstan-copper.

(CleanElectricFlame™ Plume)

Emissions, Health & Environment

  • Likely to produce CO2, SO2 and soot
  • Uses combustion gas inputs of fuel and air, commonly requiring plumbing
  • Typical 20,000 BTU/hr burners produce about 22 moles of greenhouse gasses per hour
  • Fossil fuel powered combustion often leads to toxic byproducts such as Carbon Monoxide
  • Surfaces impacted by flame may be contaminated with small size soot-like particles
  • Clean ElectricFlame™ technology produces no CO2, SO2 or soot as a byproduct
  • No toxic emissions.  Air is typical input.
  • Electricity powered, no plumbing or piping needed
  • No venting required
  • Uses only air input, no other gasses
  • No greenhouse gasses
  • Air to Air.  It's like changing your combustion flame to an electric flame
  • Highly efficient, saving on energy costs
  • Non-toxic
  • No residues left because of process
  • Improves productivity
  • May improve shelf life and quality of products

Process Impact

  • Narrow area impact when requiring intense flame, non-uniform heat application
  • Uniformity requirements may require multiple burners
  • User configurable width of plume
  • Higher efficiency
  • Requires less monitoring, saving on labor costs

Explosion Hazards

  • Highly combustible, volatile
  • Incomplete combustion may be a down-stream fire hazard
  • No combustible gasses used as inputs
  • LIP systems offer integrated over-temperature controls

Energy Efficiency

  • Flames are energy inefficient, with only around 10% of their energy able to be utilized for heat as quantized radiation may dissipate heat
  • Over 90% energy efficient
  • Realized energy savings may approach 80%. (A 30kW combustible flame may be replaced by a 6kW plasma plume)


  • Lack of precise control
  • Frequent quality control issues
  • Precise
  • Available built-in safety controls including an over-temperature shut-off


  • Noisy combustion process
  • Silent


  • Noxious odor is often noted from combustion byproducts
  • Odorless
  • Clean Process

Cost of Operations

  • Consumes expensive reactant gasses
  • Frequent downtime leads to lost revenues and costs of repair
  • Higher insurance and other costs because of emissions and other flame hazards
  • Uses air and electricity
  • No reliance on supply of combustibles
  • Less downtime, less lost revenues, less cost of repairs
  • Possibility of lower insurance premiums from improved safety
