Environmentally Friendly Debinding in Metal Injection Molding

Metal injection molding, or MIM, is a manufacturing process which combines the versatility of plastic injection molding with the strength and integrity of machined, pressed or otherwise manufactured small, complex, metal parts. The process involves combining fine metal powders with binders which allow the metal to be injected into a mold using standard plastic injection molding machines. The binders must be removed before the part can be used.

Traditional debinding methods are:

• environmentally unfriendly due to high VOC emissions
• may use solvents that are scheduled to be outlawed by the Montréal protocol
• have excessively long debinding times

Using supercritical fluids in the debinding process is faster and economically friendly.
