The 2017 Die Casting Congress and Tabletop Needs Your Papers!

Posted by Hill and Griffith Company on Mar 22, 2017 4:21:27 PM

(This week's post comes from the March 8, 2017 by NADCA in Industry News. )

The Die Casting Congress and Tabletop is interested in your paper! Submit a proposal today to the NADCA Paper System!

NADCA would like to urge all metalcasters, researches and suppliers to submit papers on new technologies, procedures, equipment, and other innovations that contribute to productivity and quality enhancement in the metalcasting industry. Especially desired are papers relating practical experience and case studies from casting personnel, and papers on metalcasting management and marketing strategies.

Here's an example of a technical article by Hill and Grifftih's Tim Cowell, Technical Director, published in DIE CASTING ENGINEER, official publication of the North American Die Casting Association

Introduction
In the Die Casting Industry, many of the castings manufactured undergo secondary operations incorporating the use of paints, adhesives and other polymers such as RTV (Room Temperature Vulcanization).  The application of these types of materials requires the polymer to bond to the metal substrate (surface) of the casting.  When this bond fails, it is considered to be an adhesion problem. For the die caster, this can be a very costly problem; therefore, it is imperative that it be solved quickly.

To gain a better understanding of the problem and its potential solution, the following points will be discussed. 

  1. What creates Adhesion?
  2. What prevents Adhesion?
  3. Assessing the Problem
  4. Solving the Problem

Read the complete article, "Resolving Adhesion Problems in Post Die Casting Operations," here.

Aluminum Characteristics by Alloy

Posted by Hill and Griffith Company on Feb 8, 2017 3:55:50 PM

(Today's post is a review of an article that was published in the Jul/Aug 2016 issue of METALCASTING DESIGN & PURCHASING. You can read the entire article "Aluminum Characteristics by Alloy" here.)

Inside the aluminum family, the various alloys exhibit marked and unique manufacturing characteristics that distinguish themselves. Generally, cast aluminum should be used for applications that require lower weight and structure without necessarily needing high strength at elevated temperatures. To help you choose the best fit, the following breaks down the castability, machinability, finishing tendencies, weldability and corrosion resistance of common alumi­num casting alloys (Table 1).

The Science of Successfully Anodizing Die Castings Substrates

Posted by Hill and Griffith Company on Feb 1, 2017 2:46:46 PM

(Today's post is the Conclusion of an article, "The science of successfully anodizing die castings substrates," which is a review of several questions received by PRODUCTS FINISHING Magazine. It was published by www.aluminumtoday.com. You can download the full article here or use this link.)

Conclusion
There is no ‘trick’ to anodizing complex alloys; there are ways, grounded in scientific reason, to approach challenges. 

 

Fig 5a and 5b: Schematic of the walls of the anodic oxide at the junction of three anodic oxide cells. An entire cell is bracketed with pink dotted lines; the central pore appears gray with repulsive forces represented by a single sphere. The fcc aluminium structure is at the bottom of the schematic with the current bias represented by bold green arrows. The forming tetrahedral structure (5a and 5b) exhibits the primary oxidation reaction at the interface between the fcc and the electrolyte in the pore by the presence of oxygen atoms on the tetrahedral structure.

The schematic on the right (5b) shows non-aluminium ions (copper colored) diffusing from the fcc lattice, through the tetrahedral anodic oxide network, into the central pore where it will be carried into the electrolyte.

Note how the copper atoms ‘pile up’ at the fcc-tetrahedral interface. This is due to the structural/compositional mismatch between the aluminium and the anodic oxide
