In order to study the piezoelectric ceramic injection molding technology, a piezoelectric ceramic injection molding platform was designed, the structural and electrical properties of the 0.94NBT-0.06BT ceramic material were investigated through injection molding equipment. The result show that the micropores of the 0.94NBT-006BT leadfree piezoelectric ceramics prepared by the injection process had significantly reduced and the density is increased. The grain size increases mainly in the form of a cubic shape, and the electrical properties are superior to those prepared by traditional solid phase methods. The density is 5.54 g/cm3, the piezoelectric constant d33 is equal to 138 pC/N, and the dielectric constant εr is equal to 1 436.
