Titanium investment casting is a manufacturing process that creates parts through the metallic replication of wax models. The produced titanium parts have a smooth finish that requires little finishing after the process. This casting process is ideal for producing complex and detailed parts that other methods cannot.

The part is made as one whole piece resulting in the absence of joints or flash lines. Titanium castings are very strong and lightweight. They are used for turbocharger components, industrial tools and instruments, and other applications in the defense, aerospace, transportation, power generation, marine, and medical industries. However, this investment casting is expensive compared to other methods such as die casting.
Nevertheless, titanium investment casting has lower equipment costs and requires less finishing. Investment casting can be carried out by hand in single or small batches, resulting in hundreds of parts at once.
How Titanium Investment Casting Functions
The process of investment casting starts with a wax replica of the part that has been hand or machine carved through injection molding. The wax pattern is connected to a sprue. Numerous patterns can be connected to the same sprue, resulting in an assembly called a tree. This connection depends on the side and shape of the part used. The tree is placed in a ceramic slurry called the investment. Then, it is dipped several times in increasingly coarse mixtures.
The tree is left to dry when the investment is thick enough on the wax pattern. Another method is to insert the tree in a flask and pour investment into the container until the tree is completely covered. Molten titanium is poured into the space and can be supplied through a vacuum. The investment is removed using numerous ways, such as vibrations or hammers, once the titanium part is cooled and hardened.
Types of Titanium Investment Casting
Different types of titanium investment casting are made to advance the method for developing the pattern. The materials used to create the pattern and their production differ significantly in these types.
Lost Foam Casting
Lost foam casting is now being used regularly due to its ability to fit into mass production and automated processes. This process was developed to enable polystyrene foam to be placed in casting sand. An aluminum die is used to create the pattern, and polystyrene beads are injected into the mold for heating. This process results in the beads melting and attaining the shape of the mold.
As the heating continues, the beads expand to replicate the dimensions and contours of the die. Finally, singular patterns are connected to a sprue and sprayed using a refractory coating of ceramic material. This type of investment casting can be used to create ornate, decorative, and complex metal configurations.
Direct Investment Casting
Direct investment casting is different from traditional investment casting because of how the pattern is created. Traditional casting creates the pattern in a die to form a wax representation. Wax duplicates are connected to a sprue and then dipped in a ceramic solution. Wax is later removed for the pattern to be filled with molten metal.
Direct casting is unique in the way the pattern is formed with various techniques. The first technique is carving the pattern by hand or machine to create a one-up version. This version is processed using the lost wax method. This process involves prototype production and assessment of dimensions for finished parts. Then, with CAD, a three-dimensional representation of the workpiece is created and designed. In relation to this, STL is a method for fabricating a solid shape using a photosensitive liquid polymer and a directed laser beam.
Water Glass Investment Casting
In this process, a water glass is used as the binding agent for the shell. Water glass investment casting has the advantages of material costs and production cycle. In addition, the surface finishes from water glass investment casting avoid defects found in traditional shell technology.
This type has processes that are less complicated and can be carried out by untrained workers. This factor results in improved production and efficiency.
Applications and Uses
The resulting titanium from titanium investment casting is used in the airline industry for assembling engine parts. In the biomedical field, titanium is used for dental implants because of its high strength-to-weight ratio. Finally, for military purposes, titanium invested casting parts are used for naval ships.
Choosing the Correct Titanium Investment Casting Supplier
To make sure you have the most constructive outcome when purchasing Titanium Investment Casting from a Titanium Investment Casting Supplier, it is important to compare at least 4 Companies using our Titanium Investment Casting directory. Each Titanium Investment Casting Supplier has a business profile page that highlights their areas of experience and capabilities and a contact form to directly communicate with the manufacturer for more information or request a quote. Review each Titanium Investment Casting company website using our proprietary website previewer to get an idea of what each business specializes in, and then use our simple RFQ form to contact multiple Titanium Investment Casting companies with the same message.
