ABSTRACT:
A method for producing semi-permanent casting tooling, including the steps of blending a high char resin with a refractory powder to form a plastic moldable material; shaping the plastic moldable material to form a green tooling body; and heating the green tooling body to convert the high char resin into carbon char to form reusable casting tooling. The casting tooling can be used in casting processes including die casting, permanent mold casting and pressure infiltration casting.
