Metal Injection Molding

What Is TiMIM?

Titanium Metal Injection Molding (TiMIM) is a manufacturing process that combines the advantages of metal injection molding with the unique properties of titanium. This technology involves mixing fine titanium powder with a binder material, injecting it into molds to create complex shapes, and then removing the binder through a debinding process.

Once the binder is removed, the remaining part goes through a sintering process where it’s heated at high temperatures to bond together and form a solid piece. The result is an intricate component made from high-strength titanium that can be used in various applications.

One advantage of TiMIM over traditional methods of producing titanium parts is its ability to produce complex geometries without requiring expensive tooling or machining processes. TiMIM also enables manufacturers to create parts with thin walls and small features that are challenging to achieve using other techniques.

The Timim parts is the best choice for the strength-to-weight profile.The other advantage of the TiMim Part is you could do many surface treatment,even process via machining for the tight tolerence.
The Timim could make the complex parts with 3mm thickness.

Another benefit of TiMIM is its cost-effectiveness as compared to other methods like casting, forging or machining which require additional finishing operations. With TiMIM, manufacturers can produce finished components directly from molds which reduces production time and costs.

Titanium Metal Injection Molding offers exciting new possibilities for creating intricate yet durable components made from one of the strongest materials on earth – Titanium!

Titanium Metal Injection Molding Process

Feedstock Formation

A mixture of fine titanium powder and a thermoplastic binder is created to form a feedstock that can be processed by injection molding machines


The feedstock is heated and injected into a mold cavity to form the part. After molding, the part is referred to as a "green" part


The binder material is partially removed from the green part, which is necessary for the subsequent sintering step


The debound part is heated to a temperature that allows the titanium particles to fuse together, creating a dense, strong part. This step also results in the part shrinking by up to 20%

Titanium is a challenging material to directly injection mold due to its high melting point, reactivity with certain gases, and difficulty in achieving uniform melt flow. However, there are alternative processes that can be used to manufacture titanium components with complex shapes, such as powder metallurgy techniques. One such technique is metal injection molding (MIM), where titanium powders are mixed with a binder material and then processed similarly to the MIM process for other metals such as stainless steel or cobalt-chrome.

In the MIM process, the titanium feedstock is injected into a mold cavity and undergoes debinding and sintering steps to remove the binder and fuse the metal particles together, respectively. This results in a fully dense and solid titanium part. It is worth noting that producing titanium components through MIM may have limitations compared to traditional machining or other manufacturing methods, as it may affect the mechanical properties or result in reduced strength due to porosity.

However, it’s important to mention that there have been advancements in technology and research focused on direct titanium injection molding, exploring ways to overcome the challenges associated with the material. These developments aim to improve the feasibility of directly injection molding titanium components in the future.

Molding titanium involves several processes, but direct injection molding of titanium is still a developing technology and not as commonly used as other methods. However, there are alternative processes for molding titanium, such as powder metallurgy techniques. Here’s an overview of some of the common methods:

1. Powder Metallurgy: In this process, titanium powder is mixed with a binder material to create a feedstock. The feedstock is then compacted into a desired shape using techniques like cold isostatic pressing (CIP) or mechanical pressing. The compacted part is then sintered at high temperatures to bond the titanium powder particles together, resulting in a fully dense component.

2. Hot Isostatic Pressing (HIP): This method involves placing preformed titanium components into a sealed container and subjecting them to high temperature and pressure. This process helps eliminate porosity and improve the mechanical properties of the titanium parts by consolidating the material.

3. Investment Casting: Investment casting, also known as lost-wax casting, is another method used for molding titanium. It involves creating a wax pattern of the desired part, coating it with a ceramic shell, and then melting out the wax. The resulting ceramic mold is then filled with molten titanium and allowed to solidify. Once solidified, the ceramic shell is removed, revealing the titanium component.

4. Machining: Machining is a subtractive manufacturing process where titanium blocks or billets are cut, drilled, and shaped using various tools and machines such as lathes, mills, or CNC machines. This method offers precise control over the final shape and dimensions of the titanium part but can be time-consuming and costly.

It’s important to note that each of these methods has its own advantages and limitations. The choice of molding process depends on factors such as the complexity of the part, required tolerances, production volume, and cost considerations. Direct injection molding of titanium is still an area of ongoing research and development, aiming to overcome the challenges associated with the material’s high melting point and reactivity.

Titanium is considered challenging to manufacture primarily due to its unique properties and characteristics. Here are some reasons why titanium can present difficulties in the manufacturing process:

1. High Melting Point: Titanium has a high melting point of approximately 1,668 degrees Celsius (3,034 degrees Fahrenheit). This makes it challenging to handle and process, as it requires specialized equipment and techniques capable of withstanding such high temperatures.

2. Reactivity: Titanium has a strong affinity for oxygen, resulting in high reactivity with air or moisture when heated. This reactivity can lead to the formation of surface oxides, which can negatively impact the material’s properties and processing characteristics. Special care must be taken to maintain an inert atmosphere during manufacturing processes to minimize oxidation.

3. Material Strength: Titanium is known for its high strength-to-weight ratio, but this strength also makes it challenging to deform or shape. It requires substantial force or specific machining tools to fabricate titanium components accurately.

4. Tool Wear: Titanium has a tendency to cause tool wear during machining due to its hardness. The abrasive nature of titanium can quickly deteriorate cutting tools, which can increase production costs and decrease machining efficiency.

5. Cost: Titanium is relatively expensive compared to other engineering materials. The high cost of raw materials and the challenges in processing contribute to the overall manufacturing cost of titanium components.

However, despite these challenges, advancements in manufacturing technologies, such as powder metallurgy and additive manufacturing processes, have made it possible to overcome many of the difficulties associated with working with titanium. These advancements continue to expand the applications of titanium and improve its manufacturability.

The industrial process of titanium is generally more expensive compared to other materials due to several factors:

1. Raw Material Cost: Titanium is a relatively rare element, making its extraction and production more costly than other commonly used materials. The mining and refining processes required to obtain pure titanium involve extensive energy consumption and specialized equipment.

2. Production Challenges: The production of titanium involves complex and energy-intensive processes, such as extracting titanium from ore through methods like Kroll process or the newer chloride process. These processes require precise control over temperature, pressure, and reactive environment, contributing to higher production costs.

3. Machining Difficulty: Titanium has a high strength-to-weight ratio and is known for its excellent corrosion resistance. While these properties make titanium desirable for many applications, they also present challenges during machining. Titanium is hard and has a tendency to cause significant tool wear, which increases the cost of machining operations.

4. Specialized Equipment: Working with titanium often requires the use of specialized equipment, such as furnaces capable of operating at high temperatures and inert gas environments. These specialized facilities and tools add to the overall cost of titanium production.

5. Quality Assurance: Titanium components often require stringent quality control measures to ensure they meet exacting standards, particularly in industries like aerospace or medical where safety and reliability are critical. Such strict quality assurance practices increase the cost of manufacturing and inspection processes.

6. Limited Supply Chain: The production and supply chain for titanium can be limited compared to other materials, leading to reduced economies of scale and increased costs for both raw materials and processing.

However, it’s worth noting that advancements in manufacturing techniques, such as additive manufacturing (3D printing), are providing opportunities to reduce costs and improve the efficiency of titanium production. As technology continues to evolve, we may see more cost-effective methods for working with titanium in the future.
