Study of glued elements of model kits under atmospheric conditions and contact with molding mixtures

Abstract

The quality of obtained castings directly depends on the model equipment and the materials used for its production. The properties of elements of model kits, made of plastic and joined using glue technology, are examined. The properties of these joints were evaluated through natural aging under atmospheric conditions. Works were carried out to analyze the influence of abrasive properties of the molding mixture and its components on the quality of glued model kits. Hardness and plasticity tests of the molding mixture were conducted using G. M. Orlov’s sample with both standard and plastic inserts, both integral and glued.
