ANALYSIS OF INJECTION MOULDING OF CERAMICS COMPOUNDS BY THE THEORY OF SYSTEMS
The main purpose of this paper is to present the theoretical systemic analysis of injection moulding of ceramic compounds (CIM) with Rophol’s theoretical definitions. The systemic analysis also includes the making of a basic model of CIM. The main principles of CIM and all phenomena connected with the process are represented by means of inputs, outputs and relations. This systemic analysis will be used as a base for easier understanding of this new technology of injection moulding.
The systemic analysis of metal injection molding
The study carried out comprises the making and description of the general model for metal injection moulding and the analysis of mentioned process with Ropohl’ s theoretical definitions. The model includes a complex of elements of metal injection technology, the elements being the core of the model, and the inputs, outputs and relations between the above-mentioned elements. The basic principles of this technology and all the phenomena connected with MIM are represented by means of inputs, outputs and relations. An exact analysis of metal injection moulding was made by a precise and systematic approach.
The systemic analysis of injection moulding
Theoretical foundations [3, 4] and Rophol's formal definitions are used to carry out a systemic analysis of injection moulding. Technical systems are classified by function classes and major outputs (table 1) [3]. Primaryshaping of products [9], e.g., of thermoplastic melts, is described in terms of function classes (eqns. 1, 2). A general model of injection moulding is given (Figs. 1, 2) and systematic analysis of injection moulding, based on Rophol's formal definitions, is carried out (eqns. 3-13).
