Cooling and Lubrication of Dies

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

Cooling

• 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

Lubrication

• 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
