Abstract
Official abstract text for this publication.
A method to manufacture reticulated metal foam via a dual investment, includes pre-investment of a precursor with a diluted pre-investment ceramic plaster then applying an outer mold to the encapsulated precursor as a shell-mold.
First claim
Opening claim text (preview).
What is claimed: 1. A method to manufacture reticulated metal foam via a dual investment, comprising: pre-investing a precursor with a pre-investment ceramic plaster to encapsulate the precursor; applying an outer mold to the encapsulated precursor as a shell-mold; coating the precursor in a molten wax to increase ligament thickness to provide an about 90% air to 10% precursor ratio; and wherein the pre-investment ceramic plaster is diluted more than about 39-42:100. 2. The method as recited in claim 1 , wherein the precursor is a reticulated foam. 3. The method as recited in claim 1 , wherein the precursor is a polyurethane foam. 4. The method as recited in claim 1 , wherein the precursor is completely encapsulated with the pre-investment ceramic plaster.
