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.

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.

Science or Black Art?, Die Casting Lubricants

Posted by Hill and Griffith Company on May 29, 2019 7:20:21 PM

Article for North America Die Casting Association (NADCA) “Die Cast Engineer Magazine” 2007 by Tim Cowell, Technical Director for The Hill and Griffith Company

Introduction

Early on in the Die Cast Industry, die lubricants were usually a concoction of various compounds that the die caster had available to him.

1. He would create different mixtures and whatever yielded the best results for his specific application was what he used. Although much was learned from this trial and error type of evaluation, this method of die lubricant development was considered more of a “Black Art” than a science. Several decades later, there are some who still believe it. Over the years, die lubricant manufacturers and others have gone to great lengths to develop laboratory methods aimed at correlating a product’s performance in the lab with how it will perform in production, and yet there are still no standardized scientific methods within the industry for evaluating die lubricants. The only true test to determine the functionality of a new die lubricant is by its introduction to the production environment.

NADCA - Die Casting Operator Training Webinar Series

Posted by Hill and Griffith Company on Feb 20, 2019 3:12:39 PM

The die casting industry depends on the skill of the machine operator for efficient production of high-quality products.

The effective machine operator understands the basic function of the process, the proper care of the die casting machine, die setup, recognition and control of basic casting defects, and the procedures that ensure his/her personal safety.



The North American Die Casting Association has created an eleven part webinar series geared towards educating operators on the do's and don'ts of running a die casting machine. Signing up for all eleven parts of this series will also grant you access to these courses through the NADCA Online Education System, which allows you to view the recordings, pdf's and support material for a full year.

NADCA Video: Die Casting Process Troubleshooting (including plunger lubes)

Posted by Hill and Griffith Company on Feb 7, 2018 5:31:16 PM

NADCA Video News Update: "Sudden stoppage of casting, because you've got a stuck plunger, but it's a combination of events ... together mean you have a problem."

The material presented in this video are some highlights from NADCA’s online webinar - Basic Approach to Process Control. This webinar covers the traditional methods of controlling the process and what feedback you use to control it. It then expands on this and shows the usefulness of some simple math terms. It allows the company to see how stable their company is in from day-to-day. It then looks at the causes of variation from that stability and how to solve the three most common causes.
