Abstract
The important advantage of the Shaw process is that it permits precision casting of not only small but also large castings. We applied the Shaw Process for making large cast tools, including press tools and die blocks that weighed 5 tons and 1/2 ton at their greatest weights, respectively. Hundreds of cast press tools and nearly 100 forging die blocks and rolls have already been produced with successful results. Much experimental and research work has been carried out for establishing the production methods that are most effective not only in casting but also in finishing. As a result of actual production, we recognize the advantage of the Shaw Process more clearly with respect to reduction of both production time and costs.
