NADCA Video News & Information

The material presented in this video are some highlights from NADCA’s online webinar - Die Spray. Die spray is essential for applying release agent to the die. It is also used to help control the die temperature and temperature distribution. This course will give an overview of the literature addressing spray. The overview will finish with applications and areas to explore in your own plant to reduce spray use and casting defects. The following topics ware addressed in this course: Die Spray, Flow rate, Spray angle, Time, Die temperature, Effects of die spray and Strategies for improved die spray.

Transcript excerpt

In addition to taking the macro view of heat, one has to remember that there are certain local aspects of heat transfer. What I mean by that is sometimes there is a feature in the casting, maybe a large heavy cross section or maybe a core that is surrounded by molten metal, which will have more heat and becomes what we call a hotspot. And this hotspot requires more aggressive cooling. We have to keep this in mind because the sprays often times are expected to take care of it. At the system level, we are removing most of the heat with an internal cooling line. But once we are faced with a hotspot in a certain area of the die, we have to spray more aggressively just to keep that area below a certain temperature and be able to move on to the next cycle. So, that’s the local aspect in which we can either increase the spray or use a cooling line such as bubblers and baffles. Lately, we are working on some formal cooling lines that are more effective in removing hotspots within the die.
