Abstract
In the past half century, the number of procedures that are basic models of metal die casting and injection molding of thermoplastics raised to more than 260. This requires a generalization and development of a general model that would cover all existing versions of these operations. On the basis of research it was found that the die casting and injection molding, according to the functions to be fulfilled, are essentially the same procedures with different materials and primary shaping parameters. The first article analyzes the historical development of the above procedures and the impact of the introduction of the new versions. This has led to the need for refined terminology, so now the terms are more precisely defined as die casting of metal melts and injection molding of thermoplastic melts. On the basis of research are listed factors affecting systemic approach of die casting of metal melts. The second part will describe the systemic analysis of die casting of metal melts.
