Precision Investment Castings

What Is an Investment Casting?

Investment casting refers to the ceramics formed around the wax patterns to create a casing for molten metal to be poured. Once the wax patterns are created, they are melted onto a gate system, dipped into slurry and sand to form a layered casing, then replaced with the melted metals such as stainless steel, aluminum, and much more. Below are some short videos with some of the steps in the investment casting process.

What Are Lost Wax Investment Castings?

By injecting wax into a permanent-molding die to form wax patterns, investment casting are the solution for many complex parts that are required in large quantities. We produce investment castings in lost wax patterns from a few grams up to 40 pounds, and can economically produce low quantities with manual tooling, or high volumes utilizing multi-cavity automatic molding tools.

The origin of the lost wax investment casting, also known as the lost wax process, stretches back in time to 1100/1700 BC. Works were created from hand sculptured wax patterns with delicate detail. During the post – WWII period, this process evolved and expanded into virtually every industry and marketplace, as seen today.
