Abstract
A process for the removal of binder material from powder injected molded parts that employs a low pressure plasma reactor to generate reactive species which react with the binder material in the injected molded part is presented. The reactive species cause the binder material to break down into smaller molecules and thereby be removed from the injected molded part.
