Metal Injection Molding (MIM) of Titanium

What is Metal Injection Molding (MIM)?

Metal Injection Molding (MIM) combines the versatility of plastic injection molding with the strength and integrity of metal. This process involves creating a paste from metal powder and a binding agent, which is then injected into a mold to form the desired shape. After molding, the binder is removed in stove, and the part is sintered to achieve final density and strength.

 

 

Benefits of MIM for Titanium Parts

            1. Precision and Complexity: MIM allows for the production of intricate and complex shapes with high precision and minimal waste.
            2. Cost-Effective: The process reduces material waste and post-processing, making it a cost-effective solution for producing small to medium-sized partsat large scale.
            3. Material Flexibility: Titanium alloys are particularly well-suited for MIM, offering excellent biocompatibility and corrosion resistance, essential for medical and aerospace applications.

 

 

 

Some disadvantages: dimensional deviations during sintering process.  And might require secondary surface finish process.

Titanium alloys, which are notoriously difficult to cast, adapt much more easily to the MIM process. Titanium Metal Injection Molding  has become a preferred method for producing small implantable medical devices with tight tolerances. These devices are crucial in the medical field due to their biocompatibility and resistance to corrosion.

 

Applications of Ti MIM

          • Medical Devices: Titanium’s biocompatibility makes it ideal for medical implants, such as bone plates and dental implants.
          • Aerospace Components: The high strength-to-weight ratio of titanium makes it suitable for various aerospace applications.
          • Automotive Parts: Titanium’s durability and corrosion resistance are beneficial in automotive components exposed to harsh environments.
Vacuum Investment Casting of Titanium Alloys

Process Overview

            1. Wax Pattern Creation: Using injection molding or 3D printing to produce an exact model.
            2. Ceramic Shell Formation: Coating the wax pattern to create a mold.
            3. Wax Removal: Melting and draining the wax from the mold.
            4. Titanium Pouring: Filling the mold cavity with molten titanium in a vacuum chamber.
            5. Mold Destruction: Breaking the ceramic mold to reveal the final part.

Advantages of Investment Casting

            • Precision and Surface Finish: Achieves tight tolerances and smooth surfaces.
            • Cost-Effective: Minimizes the need for extensive machining and material waste.Mold cost is also lower than MIM.
            • Complexity: Ideal for producing intricate and detailed components.
Why vacuum?

Because titanium might react with air under high temperature.  The ceramic shell is placed into a vacuum chamber where the oxygen concentration is virtually zero. Molten titanium is poured into the ceramic mold, filling the shell cavity. Once the titanium has solidified and cooled, the ceramic mold is destroyed and removed, revealing the final cast titanium part.

CNC Machining of Titanium

Advantages of CNC Machined Titanium Parts

  1. Durability: High resistance to extreme conditions and wear.
  2. Non-Magnetic and Non-Toxic: Suitable for medical and aerospace applications.
  3. Precision: Ideal for manufacturing complex, high-precision components.

Challenges and Solutions

  • Heat Buildup and Cutting Forces: Utilize high-pressure coolant and optimize cutting parameters.
  • Chemical Reactivity and Galling: Employ effective lubricants and use specialized tooling.
  • Residual Stresses: Implement stress-relieving techniques post-machining.

Useful Tips for Titanium Machining
Due to its exceptional properties, many manufacturers opt to use titanium to produce high-quality parts despite the machining challenges. Skilled CNC machinists and tool manufacturers have developed useful tips for machining titanium, such as maintaining a cool temperature, using specialized cutting tools, and implementing stress-relief techniques to ensure the highest quality and performance of the machined parts.

Titanium Sheet Stamping

 

Expert Tips for Stamping Titanium

  1. Bend Radii and Stretch Formability: Consider the lower ductility and modulus of elasticity compared to stainless steel.
  2. Effective Lubrication: Use lubricants containing graphite or molybdenum to prevent galling.
  3. Surface Preparation: Ensure the titanium is clean and free of defects before forming.
  4. Heating: Warm forming can enhance formability and reduce springback.
  5. Stress Relieving: Post-forming stress relief is crucial to maintain part integrity.
