Aluminum Die Casting Alloy Sources
Have you ever wondered where the aluminum alloys used in die casting come from? Although some aluminum alloys are smelted and refined from raw materials to keep up with increasing demands, most aluminum die casting alloys use recycled scrap as their primary source of material. For more information on the aluminum die casting alloy supplies view the video module at: http://www.diecastingdesign.org/alloys/supply2.htm
Die Castings Perform in Audi Space Frames
Aluminum die castings serve as main components and nodes for body componentsused in the high performance Audi A8 luxury sedan and R8 supercar. Car and Driver recently visited the production lines for both these vehicles to learn more about the construction and assembly for the see advanced vehicles.

No, not the grief that you give the person in the cubical next to you… the ribs you add to a part to increase strength using less mass.Being an additive manufacturing process die casting allows ribs to be easily integrated into your next die cast product design.Ribs may also assist in providing metal flow to difficult to fill areas.Although just like ribbing your cubical neighbor ribbing can be over applied.To learn more about ribs for die casting designs please visit: www.diecastingdesign.org/design/basic/ribs/
The new NADCA Hyper Cast program is currently underway to help lower the costs of implementing aluminum and magnesium metal matrix composites in future die cast product designs. Metal matrix composites (MMC) combine the properties of metals and ceramics into one material.Traditionally the mixing of ceramic particles into metals has been difficult and costly. Hyper Cast technology allows for the introduction of ceramic particles into a molten metal just before it is cast allowing for a significant cost reduction over previous methods.This technology takes advantage of highly exothermic reactions to rapidly create ceramic particles in the aluminum or magnesium melt. Although the focus of this project will be onlight weighting vehicles, other design applications are sure to emerge.For more information on the Hyper Cast project please visit: www.diecasting.org/research/hyper cast/

Hopefully you report to a helpful boss at work… for die cast part designs bosses are useful in a different way, often being used for standoff and mounting points for assembly components.Many times a central hole is added to a boss and this hole is often subsequently tapped to add threads without requiring a metal insert as is often needed for plastic parts. To hear learn more about bosses please visit: http://www.diecastingdesign.org/design/basic/bosses/
ZA Die Casting Alloys
Did you know that zinc aluminum alloys, often called ZA alloys, were created to offer improved properties over straight zinc alloys? ZA alloys offer distinct advantages over the zinc alloys, including higher strength, increased wear resistance, improved creep resistance and slightly lower densities.To learn more about the variety of die castable ZA alloys please visit: http://www.diecastingdesign.org/alloys/za.htm
Aluminum die castings are used in many modern applications. Although the raw surface of an aluminum die casting provides substantial protection, sometimes enhanced surface performance is required with the use of surface finishes.The new NADCA test report “Performance Evaluation of Surface Finishes on Aluminum Die Castings ” provides an evaluation of various surface finishes for aluminum die castings.

Update: Chinese Knock-offs
In a recent blog post, Chinese Knock-offs Move Beyond Gucci Bags, I described how some high-end Italian machinery makers are seeing copies of their equipment pop up in China. They’re fighting back through technical innovation, lower-cost manufacturing, service, and quality.
But it made me wonder what sort of legal recourse they have, if any?
I asked Thomas Babel, an attorney specializing in litigation and intellectual property with the law firm Ward and Smith P.A. He says that it is difficult to prove that an innovation was stolen by a Chinese company.

Aluminum 380, 383, 384 What’s The Difference?
This is an often asked question.380 is by far the most widely cast of the aluminum diecasting alloys, offering the best combination of material properties and ease of production. It may be specified for most product applications. Alloy 383 and alloy 384 are alternatives to A380 for intricate components requiring improved die filling characteristics. Alloy 383 offers improved resistance to hot cracking (strength at elevated temperatures).

Rapid cast prototypes enable parts to be assessed in a choice of alloys
When competition is fierce, the consequences of bringing a product to market late can be severe, with significant loss of market share and future profits. It is no surprise, therefore, to see the expanding use not just of rapid prototypes for investigating the form and fit of components but also components that are fully functional. Such rapid prototypes can provide high-strength, dimensionally accurate parts with all the features, operating capabilities, appearance and performance of the finished part. Because they can be delivered quickly and affordably, these rapid prototypes offer designers the means to compress development times and be more confident that the product will perform as intended for its required lifetime.

Naked Die Casting Design
The new Kawasaki Z1000 2010 motorcycle features a “Super Naked” design that shows off mechanical parts rather than hiding them with a fairing. Kawasaki Engineers used multiple die castings to provide components that look aggressive and high tech while providing high performance functionality. Each die cast piece is functional and a work of art at the same time. Smooth, stylized, single piece die castings replaced multiple parts and welded assemblies in critical frame components. In addition components that were previously die cast easily accepted new as-cast visual styling such as the engine, brake calipers, and many other components. See the dramatic effect of the “Super Naked” design concept made possible by die cast parts in the Z1000 HD Video
