Abstract
A mold has a mold cavity centered on an axis and formed with a plurality of arrays of passages each lying at least approximately in a respective plane including the mold axis. Fluid is passed through these passages in order to cool the mold, and fluid may be passed more rapidly or under greater pressure or under lower temperature through some of the passages than through others in order to increase the cooling effect. Similarly inserts may partially insulate some of the passages for cooling some parts of the mold more or less than others. A plurality of temperature sensors each connected to a respective control valve may serve to control the fluid flow through each of the passages or sets of passages for continuous cooling control.
