Proper Application of Die Casting Lubricants Reduces Blisters

Posted by Hill and Griffith Company on Dec 3, 2020 10:51:55 AM

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.

Factors That Contribute to Extending Die Life - NADCA Webinar Series

Posted by Hill and Griffith Company on Apr 29, 2020 3:57:18 PM

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.
