Knowledge-based techniques are useful in injection molding of material. In particular, the following three situations may be considered:
(i) Expert system to assist the development of molds.
(ii) Intelligent controller for the injection molding process.
(iii) Knowledge-based supervisor to monitor the process performance (e.g., deflects in the molded parts) and to take corrective actions.
In (i) mold geometry, gate location, vent locations, etc., may be considered. In (ii) material characteristics, mixing, mold orientation, pressure, temperature, etc., are important factors. In (iii), problems such as poor density, hardness, and strength, and also nonuniformities and deformations in the molded parts are of importance. Discuss distinctive characteristics of the above three categories of application; and indicate whether fuzzy logic could be effectively used in each case.
