Notes on foundry in connection with the general question of factory experience, its accumulation and use

Abstract

Of the three essential conditions of good casting, namely, temperature, ventilation of the cores and condition of the funnels, the last two must be transferred from the realm of art to the realm of craft, after which such cases can no longer occur. In the simplest way, through photographic records of model divisions and funnels, changes in molding and casting processes, and by notes on drawings the reason and purpose of each significant change in design or work process, by an individual. The personal experience can be transformed into shared, transmitted, transformed and thus collected. Then the history of the development of the factory will no longer be so much an accumulation of repeated attempts and errors in different factories, and sometimes in the same factory.
