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.

NADCA Webinars: Porosity Problems? Learn to Predict, Measure, Control and Reduce Porosity

Posted by Hill and Griffith Company on Feb 26, 2020 12:40:02 PM

NADCA surveyed designers and purchasers about the advantages and problems with die cast components. The companies that used die cast products were asked to identify some of the common problems they encounter with die castings. More than one in three specifically identified `Porosity’ as a common problem.

Since porosity is a common concern among die casters NADCA created a series of webinars focusing on the various aspects of porosity. Each presentation will not only address important information on the topic but also provide time for questions, answers, and discussion.

NADCA Publications: Die Casting Process Control

Posted by Hill and Griffith Company on Jan 28, 2020 6:53:56 PM

Chapter 8: Release Materials

Excerpt from the NADCA Publication E-410 by E. A. Herman

When the die has opened and the casting has been ejected, but before the die closes again, the cavity areas of the die receive an application of a release material. The application is usually made by spraying the material as a fine mist. Sometimes the application is not made every time the die is open, but only after some small number of shots. The purpose of the release material is to keep the casting from sticking to the die. The material is called by a variety of names including “lube,” “die spray,” “die lube,” “spray,” “parting” and “release.”

The practical die caster knows that the release material can have a significant influence on the performance of the die casting die. Sometimes, by changing the type or brand of material or by changing the application pattern or quantity, the operating performance of the die is improved. The improvements are not limited to the sticking of the castings to the die. Often surface finish, productivity, porosity or even warpage is affected. The release material and its application is a significant processing variable.


Fig. 8-1. The die designer should supply a water spray diagram like the one shown here for the processing engineer and the operating personnel. The dilution ratio must then be made to get the correct amounts for both water and release material on each area of the die.

NADCA Die Casting Facts

Posted by Hill and Griffith Company on Sep 25, 2019 4:18:49 PM

NADCA shares some common facts about the Die Casting Industry

Die casting is a versatile process for producing engineered metal parts by forcing molten metal under high pressure into reusable steel molds. These molds, called dies, can be designed to produce complex shapes with a high degree of accuracy and repeatability. Parts can be sharply defined, with smooth or textured surfaces, and are suitable for a wide variety of attractive and serviceable finishes.

Die castings are among the highest volume, mass-produced items manufactured by the metalworking industry, and they can be found in thousands of consumer, commercial and industrial products. Die cast parts are important components of products ranging from automobiles to toys. Parts can be as simple as a sink faucet or as complex as a connector housing.
