Post Die Casting Operations - Resolving Adhesion Problems

Posted by Hill and Griffith Company on Nov 15, 2018 3:32:25 PM

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 a die casting 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

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

Posted by Hill and Griffith Company on Dec 28, 2016 9:59:21 AM

Thanks to the North American Die Casting Association for giving us a possible Die Casting Process Improvement New Year's Resolution.

1. Sort: Remove all unnecessary items
2. Set in Order: Arrange items too be used
3. Shine: Clean workplace. Floors, trash, machine, etc.
4. Standardize: Simplify job and content.
5. Sustain: Maintain 5S habit

And some like to add a sixth
6.Safety: Keep Safety in mind during all these steps.

NADCA Structural Die Casting Webinar Series

Posted by Hill and Griffith Company on Dec 7, 2016 1:48:18 PM

Complimentary NADCA Webinar Series
Register: http://www.diecastingdesign.org/webinar

This webinar series is designed to inform the OEM about the benefits and capabilities of structural diecastings and their applications. This new and growing segment of the high pressure die casting industry provides die cast components for critical applications since they are high in ductility, and are also weldable and heat treatable due to extremely low porosity levels. Steve Udvardy, North American Die Casting Association - http://www.diecasting.org - Director of Research, Education & Technology will be presenting a three part webinar series.
