Effect of die material in molding equipment on deformation of plastic ceramic mixtures

The formation of the surface of a semifinished product and the movement of the mixtures in a die determine the productivity of the extrusion process, the appearance of defects and discontinuities in the preform or its parts. The deformation of plastic mixtures was considered using the Coulomb-Mohr t...

Description
Summary:The formation of the surface of a semifinished product and the movement of the mixtures in a die determine the productivity of the extrusion process, the appearance of defects and discontinuities in the preform or its parts. The deformation of plastic mixtures was considered using the Coulomb-Mohr theory and by examining the interaction of porcelain mixtures, corundum mixtures based on PVA and CMC, and hydrophobic thermoplastic mixtures based on cordierite with steel, Teflon, polyethylene, and other die materials depending on the quality of treatment of their surface and the content of temporary binder in the mixtures. Recommendations are given on the choice of die materials. 11 refs.
