KEROX DENTAL MULTI PRESSING
Cold Isostatic pressing is time-consuming but it leaves less material stress and strain, than axial press. In Kerox Dental to the axially pre-pressed blocks an isostatic manufacturing process is applied – that’s Kerox Dental Multi Pressing. The all around, extreme pressure during the isostatic pressing ensures a maximum homogenous density in all Kerox Dental blocks. Optimal blank porosity and density decrease amortization of both the milling machine and the milling heads of the dental laboratory.
AXIAL only: quick and dirty way
ISOSTATIC PRESSING (cold)
SINTERING: THE BASICS
Ensure no organic contamination and water. Lubricants and additives (that ensure press ability) burned off.
“Neck formation” by diffusion at pre-sinter. Ensure best crystal sizes and machining properties.
Particles melted, density increased, pore sizes decreased at final sinter. Ensure final metastable tetragonal structure.
