NADCA Die Casting Congress Awards 2020

Posted by Hill and Griffith Company on Oct 21, 2020 4:23:58 PM

For the last 46 years, NADCA has sponsored its International Die Casting Design Competition to showcase outstanding die cast designs while acknowledging the continuous contribution die casters provide to the manufacturing industry. As die castings become more complex, higher quality, lower cost, and more unique, it becomes important for die casters to be involved in the process early in the product’s design phase. A die casting is not a machined part, sand casting, or an extrusion. It is critical for die casters to effectively communicate to the designer requirements to make a quality casting. The winners of the 2020 International Die Casting Competition have exhibited a close relationship with their customer to produce castings that have a complex design, high quality, and ingenuity. These castings often expand the market for die casting and reduce the cost of the part compared to the previous manufacturing method.

Squeeze Casting: Part One

Posted by Hill and Griffith Company on Oct 14, 2020 1:36:07 PM

Excerpt from the June 2007 TotalMateria.com article.

Squeeze casting as liquid-metal forging is a process by which molten metal solidifies under pressure within closed dies positioned between the plates of a hydraulic press.
The applied pressure and instant contact of the molten metal with the die surface produce a rapid heat transfer condition that yields a pore-free fine-grain casting with mechanical properties approaching those of a wrought product. The squeeze casting process is easily automated to produce near-net to net shape high-quality components.

The process was introduced in the United States in 1960 and has since gained widespread acceptance within the nonferrous casting industry. Aluminum, magnesium, and copper alloy components are readily manufactured using this process. Several ferrous components with relatively simple geometry, for example, nickel hard-crusher wheel inserts-have also been manufactured by the squeeze casting process.

Quality Stabilization in Aluminum Die Castings

Posted by Hill and Griffith Company on Dec 25, 2019 8:00:00 AM

A Series of Test Shows the Impact of Carbon-Based Coatings in Aluminum Diecasting Operations.

Die castings produced with as-cast or nearly as-cast surfaces are becoming more common, where near-surface layers of the castings are machined. As a result, various problems related to the boundary between chill layers and general internal structures are more apparent. Controlling heat insulation during molten metal infusion, heat transfer during pressurization and thermal diffusion to the mold are critical to diecasting quality. Proper control of these variables will lead to dense cast structures free of chill boundaries.

In the paper “Key Issues for Quality Stabilization of Aluminum Die Castings,” Yuichi Furukawa, Toyota Motor Corp., Toyota, Japan, and Yoshiki Tsunekawa, Toyota Technical Institute, Nagoya, Japan, investigated aluminum diecasting processes. The report includes the results of a durability test of various carbon-based coatings, the effects on solidification structure and a coating’s ability to stabilize diecasting quality.


The typical microstructures of a diecast oil control valve (a) without carbon-fullerene coating and (b) with carbon-fullerene coating are shown.
