Investment Castings

In its simplest form, investment casting can be thought of as the melting and flowing of any of today’s common engineering metals and alloys into molds of virtually any net shape, to produce a near net shape component once cooled.  Comparing this to the widely accepted practice of machining components from solid raw stock, where material is REMOVED to get to the net end shape, and all of the problems associated with that, this is a very simple way to visualize just how much sense it makes to consider investment castings for cost effective manufacturing of many components.
