What is lsostatic Pressing?
lsostatic pressing is a powder metallurgy(PM)forming process that applies equal pressure in all directions on a powder compact thus achieving maximum uniformity of density and microstructure without the geometrical limitations of uniaxial pressing lsostatic pressing is performed"cold" or"hot." Cold isostatic pressing(CIP)is used to compact green parts at ambient temperatures, the cold isostatic CIP pressing technique in elastic dies allows a homogeneous density distribution across the entire body, which helps to avoid distortions and cracking due to uneven shrinkage during sintering in large part. while hot isostatic pressing(HIP)is used to fully consolidate parts at elevated temperatures by solid-state diffusion.HIP can also be used to eliminate residual porosity from a sintered PM part.
