NADCA Educational Course: Learn the Technology and Processes for Inspecting Die Castings

Posted by Beau Glim on Jul 17, 2019 10:53:25 AM

Understand the advantages of die casting inspection processes

The advantage of the die casting process is to create highly complex geometry parts quickly. Couple this with the disadvantage of die casting, producing parts with internal porosity, and the job of ensuring quality becomes more challenging. This series will take a look at some of the technology and processes for inspecting die castings.

Part 1 - Internal Inspection - This session will look at how to detect porosity in a die casting. From simple density analysis through Computerized Tomography (CT) scanning, this series will look at how the process/technology works and the advantage and disadvantages of each.
Date: July 23, 2019

Part 2 - External Inspection - This session will look at measuring the geometric dimensions of a die casting. Coordinated Measuring Machines (CMMs) have been used extensively for measuring the dimensions and form of die castings, but technology is developing new ways.
Date: July 24, 2019

Part 3 - Functional Tests - This session will look at how functional tests are developed and implemented for die castings. Parts that require pressure or leak tightness need some way to measure that.
Date: July 25, 2019

NADCA Educational Course: "Find Out How Die Casting Lubricants and Sprays Affect Casting Quality

Posted by Paul Brancaleon on Jul 3, 2019 9:40:52 AM

This NADCA series will look at, die sprays, plunger lubricants and their effect on casting quality.

With an in-depth discussion of both die and plunger lubricants we will look at their chemistry, function, application and effects on casting production and quality. The course will review pulse spray, its application and results at two production facilities. Hydrostatic spray will also be reviewed with application examples and use of hydrostatic spray.


(Illustration from the Hill and Griffith Company archives.)


Part 1 - Fundamentals - This course will go through the fundamentals of die casting lubricants. The course starts with the basics of the conventional use of external lubrication and cooling of die cast dies. The methods of spray application and the reason lube is applied to die casting dies. The function, chemistry, care and maintenance of the lubricants is reviewed. The spray section ends with review of potential defects caused by variation in spray application. For each defect, solutions to resolve those defects are taught.

Die Casting Problems - Gas Porosity And Surface Defects

Posted by Hill and Griffith Company on Jun 27, 2019 1:59:47 PM

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

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.

Die Temperature And Surface Die Casting Defects

Posted by Hill and Griffith Company on Dec 5, 2018 3:41:43 PM

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

The die temperature’s effect on surface defects and the die temperature operating window will be discussed next

  • A low die temperature affects surface defects by cooling the fluid metal stream and increasing the percent of solidified metal in the metal stream
  • If the percent of solidified metal is high, then it becomes stiff and solid and does not knit together well; And the flow forms "wrinkles", or cold flow
  • A cold die can be compensated for by having a shorter fill time - this means a higher plunger speed
  • In other words, we can exchange plunger speed for die temperature.

High Integrity Die Casting: Melting, Melt Treatment, and Transfer - NADCA Video Highlight

Posted by Hill and Griffith Company on Nov 28, 2018 11:12:43 AM

Highlights from NADCA’s online webinar

High Integrity Die Casting Melting, Melt Treatment, and Transfer

The material presented in this video are some highlights from NADCA’s online webinar - High Integrity Die Casting: Melting, Melt Treatment, and Transfer for High Integrity Die Casting. In this webinar best practices of melting, melt treatment and transfer for aluminum high integrity die casting of structural components will be presented and discussed. Many oxide and other inclusions originate from inappropriate practices with the liquid aluminum before it is cast. They cause quality issues / high scrap rates and reduced properties. This webinar explains how to avoid them by using best practices like filtering, degassing, fluxing, skimming, settling, quiescent transfer, etc.

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.
