The material presented in this video are some highlights from NADCA’s online webinar - Defects in Die Casting: Surface Defects and Other Problems. This second course covers defects caused by such things as venting problems, surface defects such as “white surface” and die spray marking. It then goes into the two main types of cracking, leakers, flash and flaking/spalling during machining.Read More
NADCA EC-515 Die Casting Defects Course Review, Basics for controlling die casting defects - By Dr. Steve Midson
- Blisters are another version of gas porosity, the gas just happens to be near the surface of the casting.
- The trapped gas is under high pressure at the end of fill and the metal may shrink and squeeze it more.
- When the casting is taken out of the die, and the die surface is no longer there to hold the casting shape, pressure from the trapped gas is able to push up a blister.

This series will look at, die sprays, plunger lubricants and their effect on casting quality. With an in-depth discussion of both die and plunger lubricants we will look at their chemistry, function, application and effects on casting production and quality. The course will review pulse spray, its application and results at two production facilities. Hydrostatic spray will also be reviewed with application examples and use of hydrostatic spray.Read More
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.Read More
The material presented in this video are some highlights from NADCA’s online webinar - Die Casting Defects - presented by Dr. Morris Murray of M. Murray & Associates. Morris discusses gas porosity and its major sources, and goes into some detail on each source.Read More
The material presented in this video are some highlights from NADCA’s online webinar - High Integrity Die Casting: Alloys for High Integrity Die Casting. In this webinar, all aspects of aluminum high integrity die casting alloys will be covered: from AA numbering, basic metallurgy, the role of alloying each element, impurities and their impact on part quality and properties, all the way to different alloy families and existing alloys currently used or under development, with their advantages and disadvantages, current and potential applications as well as achievable properties (using different heat treatments) with each of them.Read More
The material presented in this video are some highlights from NADCA’s online webinar - Die Casting Defects - Inclusions, Leakers and Cracks.

The material presented in this video are some highlights from NADCA’s online webinar - Die Casting Defects - Shrinkage Porosity. This course describes how to identify shrinkage porosity, discusses the causes, and provides corrective measures to minimize shrinkage porosity.Read More
Failure of dies is typically caused by thermal fatigue cracking or gross cracking. Other modes of failure include soldering to the die surface, erosion and corrosion of the die surface. It is clear that many factors can impact die life, including steel composition, heat treatment conditions, fabrication techniques and die casting processing parameters. The approach used in this 6-part webinar series is to summarize recent research published by NADCA on extending die life.Read More
