Abstract
This paper provides a theoretical consideration of the process of paste extrusion using a piston dispenser. The paste is considered as a highly viscous suspension of terpineol and silver particle powder. As a result of numerical modeling, the distribution of silver particles in a steady paste flow was obtained. The excess pressure in the piston depending on its speed and the effective width of the track depending on the piston speed were obtained. Modeling showed that the viscosity of the paste has the greatest influence on the extrusion process. Application of the obtained dependencies will allow you to control the paste extrusion process.
