Abstract
The invention overcomes prior art problems associated with mass-production of technology-based commercial products like watch cases, mobile telephone housings, medical appliances, etc. such as high investment in tooling, delays in production, short economic tool life, inconsistence and mismatching between parts made in different geographical locations, etc., through the use of standardized, interchangeable ceramic mold inserts.

A method for the rapid fabrication and reproduction of molds and mold components comprising:
- a. creating a cavity and core patterns of a mold;
- b. ceramic injection molding a homogeneous dispersion of ceramic powder or powders in an organic binder around each version of the cavity and core pattern to form a corresponding die block part as a green article wherein said ceramic powder or powders of said green article are not sintered;
- c. processing said green article to consolidate the ceramic powder or powders including a means for debinding said binder of said dispersion and forming a sintered ceramic mold;
- d. inserting said ceramic mold into a mold base or master mold insert adapted for use in molding metals, ceramics or plastics.
