single crystal investment casting

Single Crystal Investment Casting products have smoother surfaces and fewer defects than almost any other manufacturing method. When things are made well, they simply work better and last. It works by melting an aluminum alloy into a liquid form and transferred to their molds. This mold takes a unique form termed as single crystal structure. Once the metal is in a mold, it cools slowly to form the end product.

A slow cooling allows the metal to conform more closely with crystalline structure that constitutes the mold. This provides a consistent attack plane which is super smooth and even. These are important, particularly for aircraft components where a smooth surface is required from both safety and efficiency standpoints. When the smooth surface of an airplane part is not shaped correctly, air cannot pass smoothly over it when flying and in aeronautics "smooth" means intentional shaping.

The Benefits of Single Crystal Investment Casting

The last and probably best advantage of Single Crystal Investment Casting is that the components produced this way are able to tolerate temperatures up to 1500F! This allows them to endure much more heat without degrading or turning into a liquid. This is especially critical for components such as turbine blades in jet engines. Those fans can reach extreme temperatures when the engine is operating, with such a material needing to be durable enough not to snap.

You can imagine how important this level of precision is, especially when manufacturing medical implants which should perfectly fit into a human body. The best result, however, is if the implant fits well even before it sits inside of you; otherwise bad things happen when medical stuff gets put in wrong. Single Crystal Investment Casting is the process to produce this implants in their proper shape and size so that they are fit, safe and effective.
