  • Advanced Ceramics Manufacturing | Processes

    The most appropriate way to manufacture silicon nitride ceramic bearings is using a process called hot isostatic pressing which uses multi-axial pressing to ensure a uniform component. The start-up costs and running costs of this process will be high due to the moulds that are needed and the high temperatures and high pressures that it runs at.
