Rapid Debinding of Low Pressure Injection Molded Parts by Wicking and Subsequent Thermal Pyrolysis

ABSTRACT

When the low pressure injection molded parts are debinded by wicking and subsequent thermal pyrolysis the optimum transition point from wicking to thermal pyrolysis is just after the completion of the constant wicking rate period. Even when the partially debinded parts were heated at 5$^{circ}C$/min after reaching the 1st falling rate period the debinding defects such as distortion and cracks were not found.

Key words: Wicking, Thermal pyrolysis, Major binder, Minor binder, Capillary structure transition
