Cooling and Lubrication of Dies

Cooling and lubrication of dies is an imperative part of the overall casting or forging process.


  • Control of die temperature is absolutely essential in order to: avoid loss of mechanical strength (annealing effect), avoid cracks and plastic deformation, set temperature for best lubricant application


  • guarantees full filling (metal flow) of the die imprints
  • protects against adhesive (scuffing; fretting) or abrasive wear
  • reduces friction (for better metal flow and reduced wear)
  • reduces chemical effects (oxidation)
  • provides good release properties
  • avoids layer build-up

Spraying Technology

  • Selecting the right spraying technology decides about: parts quality, productivity and thus competitiveness of the casting/forging process
  • There are many spraying strategies – looking on the special process conditions of foundry environments, high efficiency can be only achieved when all parameter are especially adapted to the process requirements.
  • Scientific research and empirically gained experience resulted in the patented AED spraying technology
  • External Atomization nozzles are showing best results for cooling as well as for lubricant application
  • AED developed a special nozzle design which is reflecting the special conditions of foundry environments

Essential Parameter

  • Droplet Size
  • Droplet Energy Spraying DensityRatio of media (liquid) and spraying air
  • Whenever possible, AED spraying technology is separating cooling and lubricant application
