<p>A method of determining conditions for injection molding capable of determining optimum molding conditions quickly and easily, in which, a processor (12) of a control device loaded with an expert system including a condition table listing a plurality of conditions each comprising a combination of information on metallic molds, data on resin, molding conditions, data on faulty molding, and molding monitor data and a weight table listing weighted countermeasures against faulty molding set for every condition, retrieves from said condition table a condition most proximate to a trial injection condition discriminated on the basis of information on metallic mold, data on resin, and molding condition set before start of trial injection, molding monitor data detected during trial injection, and data on faulty molding inputted after finish of trial injection, and, referring to the weight table, determines a countermeasure against faulty molding corresponding to the condition retrieved and greatest in weight. While trial injection is repeated according to the countermeasure against faulty molding with molding conditions changed, the processor changes, as required, weight of the faulty molding countermeasure taken in the previous trial injection on the basis of the result of comparison between faulty molding in the previous trial molding and that in the current one.</p> |
