Methods of injection molding an article

摘要

Embodiments of the invention relate to injection mold components, assemblies, and molding system that include superhard materials. Such injection mold components, assemblies, and systems may decrease wear of certain injection mold components, which may result in improved productivity of the injection mold and molding systems that utilize such components.

主权项

1. A method of injection molding an article, the method comprising:
providing a mold that includes a mold component having; providing a superhard material bonded to a cemented carbide substrate, the superhard material being formed separately from the mold component, the superhard material including a wear-resistant surface, the superhard material including sintered polycrystalline diamond having a plurality of bonded diamond grains defining interstitial regions in which at least a portion thereof include a catalyst therein; and performing at least one of:
producing relative movement of the wear-resistant surface relative to one or more other mold components; orflowing molding material in contact with the wear-resistant surface.
