Abstract

This paper presents methods for determining dimensions of the mold hollow in order to obtain the most accurate thermoplastic gear by injection. The software Lama 16C allows slightly fluctuate certain gear parameters, their drawing, comparison and tracing of the parameters change affecting the geometry and gear parameters. After changing replaceable mold inserts in experimental tools and after applying corresponding procedures of measurement and control of the obtained thermoplastic gears, their dimensions have been checked in order to determine the optimal dimensions of the mold hollow as the most prominent factor of the desired shape.
