If you are a regular reader of the Aerospace Manufacturing Magazine, you may have come across PI Castings’ feature in the March 2017 issue which explains how the fine surface finish of investment casting can result in cost savings, shorter lead-times and superior dimensional accuracy in production.

The fine surface finish that can be produced by investment casting is one of the many key qualities that attracts design engineers to this method of casting when they are determining the most appropriate route to manufacture for their components.

In the article, Sean Curley of the PI Castings’ quality department explains why the 3.2 Micron surface finish of investment casting can result in the aforementioned benefits.

The feature explores how the fine surface finish allows for tight tolerances to be achieved during production, reduces the need for machining and finishing operations, and contributes to a better quality of finish; especially when parts are destined for final surface treatment processes, such as painting.
