What kinds of forming oils are there?

There are 3 main technologies of forming oils depending on the base oil. 

  • Neat/straight oils are like standard oils with a viscosity higher than 5cSt at 40°C. They are used for the easiest operations.
  • Vanishing /evanescent oils are formulated with volatile solvents that evaporate during the operation only leaving the additives behind to do the job. The surface is then easier to degrease. With some products it is even possible not to degrease and move directly to post treatments. These products have a viscosity under 5cSt and a low flash point (<150°C).They are used for the easiest operations. 
  • The third technology covers water-based products. The oil is diluted from 5% to 30% in water to enhance cooling properties. This is interesting for high-speed operations.
