NADCA's Congress West Returns! Spotlights Die Casting Lubricant

Posted by Hill and Griffith Company on Dec 13, 2017 2:01:52 PM

Room Block Closes December 21 - Register Today!

From the Dec 13, 2017 Newsletter: 

NADCA is excited to announce the return of Die Casting Congress West on January 11-12, 2018 at the Hilton Long Beach. The Congress will feature technology highlights of our Congress in Atlanta earlier this fall. The event will kick off with a cocktail reception on January 11 and lead into a full day of presentations on January 12.  Presentations to include: 

Session: State of the Industry
An update on the current state of the die casting industry.
Paul Brancaleon, North American Die Casting Association 

Session: Structural
The ability of the die casting industry to improve cast component performance will help die casting continue to be a relevant manufacturing process. Structural die castings have been identified as having the potential to expand markets for die castings by providing improved mechanical properties. Higher strengths and elongations allow die castings to be used as structural, or even crash-worthy, components on automobiles. Research on alloys and heat treatments used in structural die castings will be presented during this session.
Paul Brancaleon, North American Die Casting Association 
 
Session: Die Coatings  
Die casting is a harsh environment for dies and tooling. Heat checking, soldering and wash-out are all issues that die cast tooling faces. Research is being performed on the use of coatings to not only protect the tooling, but also reduce the amount of die spray needed. Protecting the surface of the die, as well as the shot sleeve inner diameter, will extend the life of the die and sleeve, which in turn leads to better quality castings.
Steve Midson, The Midson Group
 
Session: Computer Modeling
To make higher quality die castings the die casting process needs to be understood on a fundamental level. Transforming the basic principles of die casting into mathematical equations, the process can be simulated on a computer. Advances in computer simulation lead to process improvements, improved tooling, and optimum utilization of new alloys.
Al Miller, The Ohio State University

Session: Advanced Technology    
Customers are constantly looking for higher quality parts at lower costs with shorter lead times. There are limits to the benefits of improving process control. Eventually, new technology is required to meet the demands of new products or stricter quality and functional requirements. This session will look at some of those new technologies and how they can be utilized to improve die castings.  
Beau Glim, North American Die Casting Association

The Congress is sponsored by a limited number of Suppliers that attendees will be able to meet with to learn more about products and services available to the die casting industry.

Sponsors Include: 
Thermtronix Corp
BuhlerPrince Inc
Visi-Trak Worldwide, LLC
Frech USA Inc
B&L Information Systems Inc
Oerlikon Balzers
MAGMA Foundry Technologies Inc
Hill and Griffith Co
Hildreth Manufacturing LLC
Midland Technologies, Inc
Anviloy By Astaras Inc
HPM North America Corporation

The cost is just $20 for NADCA Members and $50 for Non-Members (note that registration includes access to the cocktail hour as well as breakfast and lunch on January 12).  In addition, if you will be sending 5 or more people we are offering special pricing.  

Information and registration can be found herePlease note that the housing block closes December 21, so make your reservations right away! If you have any questions please feel free to contact Melisa Ryzner, CMP at mryzner@diecasting.org or 847.808.3161.


A Short History of the Die Casting Lubricant

Die casting has progressed over the last sixty years from small parts of lower melting metals and alloys such as zinc, to castings of large parts, such as tailgates and engine blocks with high-melting alloys of aluminum or magnesium.

The metals are injected into a mold very quickly and under high pressure. The pressure is maintained until solidification, which produces accurate parts with good surface finish. Depending on the alloys, it's possible to obtain a variety of physical and mechanical properties over a range of sizes and weights.

As die casting conditions grow more severe with higher temperatures, pressure and increased part size. Higher performance die casting lubricants are needed to enhance the process, as long as they don’t negatively affect the quality of the casting.

The Hill and Griffith Company is dedicated to providing high performance die casting lubricants, application and management technologies to continue to increase the size, quality and strength of diecast parts and assemblies.

Application of die casting lubricant

Posted by Hill and Griffith Company on Dec 6, 2017 3:49:04 PM

Proper die casting lubricant and its application ensure that parts eject easily and without defects.

Also called mold release or die spray a precise amount of it is sprayed onto the steel mold before each shot. It evaporates when it comes in contact with the hot steel leaving just the right amount of lubricated coating and required temperature of the mold.

If it cannot evaporate fast enough or if the tool cools too quickly, the molten metal may become more porous. Porosity is always caused by the die casting process. Proper component design, draft, overflows and venting can reduce porosity; as well as specially formulated die release agents.

If there is not enough, the component may stick in the die and cause defects. The larger the draft; the less mold release required. 

Die lubricants are formulated specifically for zinc, aluminum or magnesium and the complexity of the die casting. 

Water-based lubricants provide a release agent and die cooling. Oil-based lubricants may be more appropriate for painted or plated components. It doesn’t provide the same cooling as water-based. Oil-based allows for an increased temperature which may be required for high-quality finishes.

NADCA News: Die Casting Tooling Coatings & Congress West

Posted by Hill and Griffith Company on Nov 29, 2017 3:20:39 PM

Video News Update: Coatings for Die Castings: Conventional Coating Processes

From the November 29, 2017 Newsletter: 

Video News Update: Coatings for Die Castings: Conventional Coating Processes



The material presented in this video are some highlights from NADCA’s online webinar - Coatings for Die Castings: Conventional Coating Processes - presented by Stephen Midson of The Midson Group. Conventional coatings (nitriding, carbonitriding) have been used for some time on die casting dies. This introductory webinar will review these processes, and describe die failure mechanisms (soldering, erosion) they are used to address.
