Abstract

Determination of injection molding machine setting is usually carried out by an experienced machine operator. By considering the mold geometry, polymer type and machine model, the operator decides an initial setting based on his own knowledge. This knowledge could include material and machine data, empirical rules and simple formulae. A computer system based on this knowledge is developed for computing an initial setting for an injection molding machine. The system first determines the possible processing conditions by considering only the material type and machine model. Then an initial processing condition is determined from these possible conditions by reasoning using the empirical rules. This reasoning is formalized by fuzzy logic. Finally, the machine setting corresponds to the determined initial processing condition is calculated by simple formulae. The performance of the system has been verified by experiments. Results show that the computed setting is acceptable for simple geometry.
