The Application of Micro-Flow Extrusion Forming Technology in the Denture Preparation

Abstract

The forming process of denture preparation based micro-flow extrusion was researched. The dental ceramic materials having health care function was preparation. Through analysis and calculation, the rheological properties of the ceramic slurry confirmed to be pseudo-plastic fluid . The extrusion head as a key part was designed. The pressure distribution and velocity distribution of the internal flow field of extrusion head were simulated by using START-CD software ,the analysis result can used to guide the optimal design of extrusion head.
