Our Titanium Alloy Injection Molding Capabilities
Our in-house factory can produce titanium alloy parts ranging in weight from 0.02 grams to 200 grams and in thickness from 0.04 inches to 0.5 inches. Our titanium alloy injection molding process achieves a particle density of over 99.5%. TiMIM components can be extremely fine, even down to the microscopic level, incorporating threads, scribing, microgrooving, and many other features required for modern electronics.
Furthermore, our near-net-shape process enables extremely short production cycles. The complete production cycle for a MIM part typically takes three to five days, including injection molding, debinding, sintering, and final inspection. We are committed to serving our customers with the best quality and price. For castings, part and mold design are also crucial.

Niobium addition improves corrosion resistance compared to Ti-6Al-4V. They are used for biomedical implants and aerospace components requiring high biocompatibility.
Ti-5Al-2.5Fe (Grade 38)
Iron addition provides better machinability and enforceability. They are used where machining/fabrication of MIM parts is required—an excellent combination of strength and toughness.
Ti-3Al-2.5V (Grade 9)
Lower aluminum and vanadium content gives superior weldability. Suitable for chemical processing applications requiring corrosion resistance and weldability.
Ti-15V-3Cr-3Al-3Sn
A high-strength titanium alloy used for fasteners and compressor parts in aerospace applications. Provides excellent creep resistance.
Ti-10V-2Fe-3Al (Grade 20)

Ti-15Mo-5Zr-3Al (Grade 21)
Added molybdenum and zirconium provide exceptional corrosion resistance. Used in aerospace fasteners and components needing corrosion protection.
Precautions for MIM Manufacturing of Titanium Alloy Parts
Titanium faces unique challenges in the sintering stage of the metal injection molding (MIM) process. One of the most critical factors is controlling oxygen content. Excessive oxygen absorption can occur during sintering, especially at high temperatures. While increased oxygen content can improve tensile strength, it also reduces ductility, making parts more brittle.
Titanium powder should be processed in a clean environment, and sintering should be carried out in a high-purity inert atmosphere to inhibit oxidation. For applications requiring enhanced mechanical properties, hot isostatic pressing (HIP) can be used after sintering. HIP increases the density of titanium parts by uniformly applying high pressure and high temperature, thereby improving strength, fatigue resistance, and structural integrity. It also helps eliminate residual porosity and refine the microstructure, making it particularly suitable for critical components in medical and aerospace applications.
Non-Traditional MIM Parts Production
We are your preferred partner for producing large, complex metal injection molded (MIM) parts. Leveraging our advanced metallurgical technology, we are able to produce larger and more complex parts that were previously impossible with traditional MIM processes. The uncertainty of isotropic shrinkage in traditional MIM materials increases significantly with part size, typically leading to high dimensional variability, poor dimensional stability, and high material processing costs. Elimold’s innovative approach utilizes high-particle-concentration materials and processes them on mature equipment, enabling high-volume production of complex parts, exceeding 200 grams, using MIM technology.

Produce Titanium Alloy MIM Parts Fast and Efficiently
Using Elimold’s titanium alloy MIM technology, you will achieve higher production efficiency. During injection molding and sintering, you can obtain batches of parts with consistent quality in shorter cycle times. While molds do require some initial investment, the unit cost per part decreases significantly in the medium to long term. Simultaneously, many complex machining steps are reduced, thereby lowering labor costs and accelerating production cycles. For our metal injection molding (MIM) process, almost all powder is used directly in the final part, minimizing waste. Choosing this titanium processing technology not only yields high-performance parts but also reduces raw material loss and improves overall production efficiency.
