Hot moulding of zirconia micro parts

Influence of dispersant, storage time and temperature on the rheological properties of zirconia–paraffin feedstocks for LPIM

“…by using a LPIM machine. 22 For rapid prototyping processes, where the feedstock is moulded manually into soft silicone moulds, shear rates below 1000 s −1 have to be expected.…”

Impact of powder morphology on quality of low-pressure injection moulded reaction-bonded net shape oxide ceramics

“…For the production of ceramic micro parts, low-pressure injection moulding (LPIM) has already proven to have excellent moulding capabilities and provides a high surface quality. [9][10][11] A combination of reaction-bonding net shape oxide ceramics and low-pressure injection moulding enables the economical production of ceramic micro devices with complex geometries and high aspect ratios. 12 The required powder content for feedstocks of reactionbonded net shape oxide ceramics to achieve zero shrinkage can be calculated as follows:…”
