Melting and casting can be carried out in high technology equipment, but they are only the culminant point in the metallurgical performance of the investment casting process: melting and casting are of crucial importance even in the unfavorable sense, but they cannot correct or wipe out the effect of metallurgical errors that have been made in preceding phases. Some aspects of the phases preceding melting and casting, like mold optimization and flask treatment, are also considered, because too frequently these operations receive insufficient attention or are considered separately from the whole process. Then it is discussed how control of the subsequent melting-casting phase, selection of the operating parameters, and process data collection that are possible with the most up-to-date machines can lead to improved product and high productivity in the jewelry factory.
