Article Excerpt: Improving Surface Finishing of Die Castings

Posted by Hill and Griffith Company on Jul 31, 2019 3:07:59 PM

Upfront Collaboration Between Casting Supplier and End User Can Improve Post-Casting Processing, from Finishing to Painting

by Joe Miller, Chicago White Metal Casting Inc., Bensenville, Illinois

A plastic bumper joining this two-part case conceals all parting lines, thus avoiding any edge polishing.

In the die casting process, metal molds—or dies—are preheated and coated with a die release agent prior to the injection of molten metal that is forced into the die under extreme pressure (usually from 10,000 to 15,000 psi). But once they are ejected from the die, most parts have a journey ahead of them before arriving at the shipping department.


The large majority of die castings require specific coatings and finishes, polishing and/or painting. These processes are necessary to meet cosmetic/decorative appearance requirements, enhance wear resistance and/or provide a protective barrier against corrosion.

Article Review: Better Interaction - Key to Better Die Casting

Posted by Hill and Griffith Company on Jul 24, 2019 8:00:00 AM

The various factors from the plunger tip, plunger gap, shot sleeve, temperature and other factors are important to get right to avoid scrap.

In this article, Paul Robbins, with Castool Tooling System, identifies multiple methods to improving die casting processes of injecting molten alloy to the die cavity.

Factors to consider
The best opportunities for improvement is found in the delivery of the alloy to the die. Both the shot sleeve and the plunger offer opportunities for improvement. Read the entire article here, on the Castool.com site.

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.

SME - Manufacturing Processes - Die Casting (including die casting lubrication and application)

Posted by Hill and Griffith Company on May 30, 2018 4:35:04 PM

Die casting is a high precision, rapid parts-production process involving the high pressure injection of molten metal into a die having a cavity of the desired part shape.

Part of the Fundamental Manufacturing Processes Video Series, this program explores the common die cast metals and their various properties, as well as die casting machines and die cast tooling. The die casting machines segment covers in detail both the hot-chamber and the cold-chamber machine types. Also discussed is the importance of die casting lubrication and application in die casting, clamping systems, the use of accumulators and pressure intensifiers, and machine controls and automation. The die cast tooling segment examines the various die production materials and techniques. In addition, terms such as cover die, ejector die, fixed cores, movable cores core pulls, venting, die cooling, and draft angles are clearly defined.
