Of the ten distinct techniques listed in Table 1, three are in general commercial use and, together, account for more than 95% of world diecasting production.

These standards, specifications, and requirements must be economically achievable (producing castings of an unnecessarily high standard is uneconomical) and they can only be arrived at after consultation between the supplier and the consumer.
