NADCA Webinars: Cooling Line Placement in New Die Steels

Posted by Hill and Griffith Company on Sep 23, 2020 5:17:31 PM

The material presented in this video are some highlights from NADCA’s online webinar - Cooling Line Placement in New Die Steels. Increasing productivity is important to the die casting industry. The R&D course, Cooling Line Placement in New Die Steels, addresses how close cooling lines can be placed to the cavity surface and why. This course includes an explanation of the technology and successful results of use.

Cooling Line Placement in New Die Casting Steels

Transcript from Die Casting Defects

Considerations

Present cooling line design guidelines recommend not placing cooling lines closer than 0.75" fromthe cavity for water, and 0.5" for oil. This recommendation is based on the mechanical properties of Standard H13.

Can we consider closer and larger cooling lines today?

The risk of thermal shock leading to gross cracking is the main reason for avoiding high thermal gradients.

Why larger cooling lines? Why closer to the cavity? Well, it all equates to the number of parts they can produce in a given period of time. The shorter the cycle time in die casting can be achieved by faster extraction of heat from the cavity. So, if we place the cooling lines closer to the surface and/or use larger cooling lines. That provides the means for a faster heat extraction. I say potential. So, why is that not a given? Because each cooling line and the die steels have a finite ability of turninng away heat or BTUs from the cavity surface. We can only ask our die steels to do so much.
