For the third time in six years, O’Fallon Casting was recognized in 2014 by the Investment Casting Institute with their “Aerospace Casting of the Year” award. 

Aeromet International PLC has overcome this obstacle with development of a truly castable 200-Series alloy, A20X, widely regarded as the strongest commercially available cast aluminum alloy in the market today.

The Sales Engineering team at O’Fallon Casting acts as the primary point of contact between the business and its customers. Because of this, it is critical that all of the technical and quality requirements of customer products are understood by each Sales Engineer.

One sometimes overlooked aspect of part design is the High Cost of Part Count, that unintended cost for NOT combining the assembled features of a system into a single piece structure.

Investment Casting is a foundry process known for producing highly accurate, near-net-shape, castings.  Once known as the “Lost Wax” process, much as Sand Castings are produced from sand molds, and Die Castings are manufactured from metal dies, Investment Casting derives its name from its ceramic molding material that is known as “Investment”. 

O’Fallon Casting was pleased by a video that has been released by the American Foundry Society on their MCTV – Metalcasting Television.

On Dec 12 2012, Vince Gimeno and Tim Hill of O’Fallon Casting, attended a meeting at the University of Wisconsin-Madison on the ultrasonic dispersion of nanoparticles for strengthening of cast aluminum alloys. 

O’Fallon Casting offers Investment Casting-101 classes to its customers to help educate their Engineers on the Fundamentals of Investment Casting design.  

Castings provide a cost effect method to provide the Near Net Shape of a configuration, but critical details are inevitably machined.  The machining first cut should always be from the Datum Points of the casting, and just in case something goes wrong, it is important to retain the original casting datums.

The selection of datum surfaces, and assignment of the datum point (also called Tool Points) locations, is a critical consideration for good casting design, so here are a few helpful tips:
