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.

The Importance of Lubricants in Die Casting, guest blog by Premier Die Casting Company

Posted by Hill and Griffith Company on Jul 18, 2018 8:45:29 PM

It’s impossible to do effective die casting without proper lubricants. What are the proper lubricants for die casting and what are the different die casting lubricant benefits to consider? Here is some basic information to get you started from the Premier Die Casting Company as a guest blog.

Lubricants and the Die Casting Process

Once you’ve poured the liquid metal into the mold and it has hardened, you need a way to remove the completed part from the die safely and without damaging the part. The release agent we use to make this happen is called die spray or die lubricant. Before each shot, we apply the die spray or lubricant to ease the part removal from the mold. It’s important to use a precise amount of die lubricant — not enough, and the part may stick, leading to defects and shutting down production. Too much, and you may end up with die lubricant that fails to evaporate, leading to porosity inside the casting and poor surface finish of the part.

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.

It's Not Your Father's Die Lube Anymore

Posted by Hill and Griffith Company on Sep 27, 2017 8:38:41 PM

Introduction

In recent years, die cast lubricants have changed greatly! Die casters who have been around long enough will remember "traditional oil-based die lube products" (1). Subsequent generations have seen a conversion to "water-based prod­ucts" and in some limited applications a "dry powder."

With every generation, a better, faster, different prod­uct has been developed by the various manufacturers of die lubricants. The good news is that all of these manufacturers and universities have dedicated a great deal of time, money and effort into the pursuit of better products.

For the benefit of this discussion, the informa­tion contained will review advances in technology without reviewing the "traditional oil-based products" or the "dry powder" products. The discussion will review advances that have occurred in the "water-based technology". The "water-based technology" appears to be the predominately used product for applications where the die lubricant contributes to the external cooling of a die (2) Water has proven to be a great benefit to the characteristics of die coolant (3,4). Therefore, it is not necessary to review that aspect of die lubricant technology, as significant work has been completed at universities (such as Ohio State) and various manufacturers.

Die Casting Plunger Lubricants & Porosity: How they interrelate

Posted by Hill and Griffith Company on Sep 13, 2017 3:52:41 PM

NADCA Congress Session Spotlight - Tim Cowell, Technical Director at The Hill and Griffith Company to present at the Die Casting Congress & Tabletop 

In the weeks leading up to the 2017 Die Casting Congress & Tabletop NADCA highlights information on papers that will be presented during the congress sessions. The following paper is scheduled to be presented on Wednesday, September 20: Computer Modeling II - 8:00-9:30 AM, Session Chair: Charles Monroe

Plunger Lubricants and Porosity: How they interrelate within the Die Casting Process
Timothy Cowell, Technical Director, Hill and Griffith Company

High Pressure Die Casting is a manufacturing process in which molten metal is injected, with a die casting machine using applied force and high pressure, into a steel die to form various products (castings). Within this process, there are large numbers of variables that need to be controlled to make an acceptable casting. If these variables are not controlled then defects within the castings (parts) occur making them unusable.
