Castings offer a unique capability to combine multiple features into a unitized structure that reduces the total part count of an assembly and improves the overall affordability of an engineered product.

Customers of O’Fallon Casting are entitled to a free Concurrent Engineering Service to assist in their design of affordable cast products.  Concurrent Engineering is remarkably easy to accomplish and is time well spent.  O’Fallon Casting hopes that, as a result of Concurrent Engineering, its customers will design better castings and so be more inclined to engineer other parts as foundry products.

The Investment Casting process provides two primary cost benefits to its customers.  First is its Near-Net-Shape capability that stems from the dimensional precision of the process and because no draft angle is required.  Secondly the Investment Casting process provides an ability to combine multiple pieces into a One-Piece structure with few design constraints and without a major impact to cost.

ToughMet is a strong, stiff, corrosion resistant, and galling resistant bronze alloy.  It possesses the additional attributes of being very low friction and resistant to wear.

elative to other foundry processes Investment Casting is a very precise method to produce a Near-Net shape cast product.  This capability stems both from the repeatability of the process and that a draft angle need not be added to cast surfaces.  As with all manufacturing processes there will exist some part-to-part variation that needs to be accommodated by a dimensional tolerance.

The Investment Casting process provides two main cost benefits to its customers.  First is its Near-Net-Shape capability that stems from the dimensional precision of the process and that no draft angle is required.  Secondly the Investment Casting process provides an ability to combine multiple pieces into a One-Piece structure with few design constraints and without a major impact to cost.

O’Fallon Casting has published its first “Investment Casting Design Guide” which is now available for free download on the OFC Website

It is a well-known axiom that 70% – 90% of the cost of a product is the result of design decisions.  Although we might debate as to the preciseness of this estimation the fact remains that design is key element to the manufacturability, availability, reliability and overall affordability of any manufactured product.

O’Fallon Casting had the pleasure of addressing both the American Foundry Society’s Metalcasting Supply Chain Summit and Metalcasting Design Summit held in Chicago on February 3rd and 4th.

The particulate Silicon Carbide reinforcement in Aluminum Alloy Metal Matrix Composite enhances this lightweight material with improved mechanical property attributes for stiffness, vibration dampening, wear resistance, high thermal conductivity, and low coefficient of thermal expansion.
