ABSTRACT:
The invention provides methods for producing semi-permanent casting tooling, as well as semi-permanent casting tooling apparatus. Casting tooling including a blend of high char resin and refractory powder; casting tooling prepared from a blend of sol-gel ceramic precursor and refractory powder; and a preform including a leachable core as well as methods for their production are provided. The casting tooling of the invention can be used in casting processes including die casting, permanent mold casting and pressure infiltration casting. Also provided is an investment mold casting technique compatible with a pressure infiltration process.
