Metal Injection Molded Titanium: Mechanical Properties of Debinded Powder and Sintered Metal
Journal of Materials Engineering and Performance, 2020Metal injection molding (MIM) is a production technique to produce small and complex titanium part. During debinding, the elements of binder may react with titanium powders, form the interstitial elements and influence the mechanical properties of sintered part. Accordingly, the chemical composition and hardness properties of commercially pure titanium,

Metal Powder Injection Molding Process for Manufacturing Adapter Component
Key Engineering Materials, 2014Adapters are a component of the output system in the internally geared hub for a bicycle. Originally, adapter parts were produced by a machining process with low productivity and material usage rate. In this study, the metal powder injection molding (MIM) process has been applied as an alternative manufacturing method to the machining process ...
