  Industry Member(s):  NSF
   

Brief Project Description:
 

• It is important to note that the powder molding and sintering process differs from that of polymer molding.
• After a ceramic or metal powder is molded at a low temperature and pressure, the body is heated to high temperatures, eliminating the binder and the interparticle porosity to form a dense ceramic or metal part.
• The sintering step produces additional and significant dimensional changes.
• The goal of this project is to develop a detailed understanding of these changes in the mold's composition and the computational methods for predicting as-formed shapes.
