Manufacturing process

Axial pressing method:

The first operation is the axial pressing of the zirconia. Products are manufactured in standard shapes like discs, cylinders and blocks according to market requirements. It is however possible to comply with our customer's specific requirements and produce customized product shapes and dimensions.

Isostatic pressing method:

After axial pressing, during which the semi-finished parts are given their necessary consistency, an isostatic pressing process is performed on all the products. The isostatic pressing process ensures all parts have a homogenous density and shrinkage distribution. This guarantees that during and after the sintering process, the products will always have extremely constant material characteristics.

Mechanical processing method:
Following the isostatic pressing process, the semi-finished parts can be shaped or machined to achieve the preferred geometry in accordance with product specifications.

Pre-sintering process:
During this process, the semi-finished parts are sintered at a specific temperature that optimizes the subsequent processing stages. Specific, computer controlled kilns are used for the heating up, dwell and cooling down phases.
The shrinkage factor of each production batch is carefully determined in our laboratory. The use of this shrinkage factor ensures that during final sintering, finished parts will have the dimensions required.
