A Study of Elastic Aftereffect in Injection Casting of Thermoplastic Feedstocks Based on SiC, AlN, WC Powders and Its Influence on Mechanical Properties of the Workpiece Material

摘要

The paper addresses the changes in dimensions of products prepared from thermoplastic feedstocks based on SiC, AlN, WC powders and paraffin by injection molding. The authors study the influence of the process pressure, temperature, and powder particle size on the elastic aftereffect in the product material as well as the influence of the injection casting variables (pressure and temperature) on the ultimate bending strength of the product material.
