Metal Injection Molding, a Cost-Effective Path for Large Production Runs
A major difference between 3Diligent's metal injection molding service and other injection molding methods is the post-processing steps required to create a finished metal part.
Metal Injection Molding Process Overview
Metal injection molding starts with the fine, powdered metal. These particles are filtered into a barrel cavity, along with a binder agent, that rotates and mixes the two agents to an injectable consistency. The rotating rod quickly jams forward, inserting the mixture into the negative space of the workpiece. Air escapes the workpiece's negative space through microscopic holes, allowing the metal filament to fully fill the cavity without exiting the workpiece as the air did.
After the parts are compressed and ejected from the cavity, they must go through post-processing, often a de-binding step to remove the binder agent and a sintering step to solidify the metal part for end-use.
