5 Steps to Identify Casting Defects

Posted by Hill and Griffith Company on Aug 21, 2019 2:38:22 PM

Excerpt from the article in Global Casting magazine's September 2018 issue

The procedure of identifying, diagnosing and minimizing or eliminating crucial casting defects is important for a foundry to run in a low-cost, and high-efficiency mode. It can disprove incorrect conventional wisdom and show that unexpected methods are actually the best way to move forward. To do this, there are three keys to remember:

1. Focus on identifying a casting defect on the basis of its appearance.

2. Be aware of the interactive nature of foundry processes and variables.

3. Use rigorous experimental design methods to study complex causes of defects.

NADCA - Thermal Control Webinar Series - Diecasting

Posted by Dr. Morris Murphy on May 8, 2019 9:29:10 AM

Controlling the temperature of a die casting die through the location of cooling lines is critical to performance and die life.


A properly designed system of water and/or oil lines will process heat energy so the die can be operated productively with the highest part quality possible. NADCA has created a three level approach to addressing thermal control. This series is broken down by beginner, intermediate and advanced courses suitable for people with varying levels of knowledge in this area.

Die Casting - Surface and Gas Porosity Defects

Posted by Hill and Griffith Company on Feb 13, 2019 10:57:59 AM

NADCA EC-515 Die Casting Defects Course Review, Basics for controlling die casting defects - By Dr. Steve Midson

Gas porosity is the biggest single problem in die casting. High gas content prevents heat treating or welding and makes strength unpredictable.

  • There are three major sources of gas porosity for die castings: Trapped air, Steam, Gas from lubricant
  • Gas porosity is round and generally smooth, although it can be flattened to some extent by pressure
  • The actions to reduce gas porosity, in general, are not the same as the actions for reducing shrink porosity
