STEP TWO: Debinding to Brown Part
The function of debinder is to remove most of the binder polymers from as-printed green part. The debinding process is relatively simple by immersing green parts into a proper debinding fluid for a certain period of time. Debinding equipment includes water debinding, solvent debinding and catalytic debinding. Typically, our debinder is designed to be more environmental friendly and much safer by using mild oxalic acid rather than nitric acid. Also, our debinder is available for batch processing and simply operation.
Once the binder polymers has been removed, the part is referred to as brown part and is ready to be densified into a fully metallic part via sintering.
