The Recessed
In order to cast light-weight slugs and for quick cooling, the recessed mold is made. This mold will cast slugs with cavities, or recesses. The base of this mold is the same as the universal adjustable. The lower surface of the cap has rectangular projections and grooves. The molten metal is forced into these grooves and forms the supporting ribs beneath the type face. The rectangles form the recesses. The weight of the slug is reduced about one-third. A more solid slug is formed because there is less air to be displaced from the mold. There is less metal in the mold cell, therefore it cools more rapidly than the regular universal adjustable. These molds require special left-hand liners and are adjustable for body size from 10- to 14-point and all measures from 8 to 30 picas, except the half-em measures. For these restricted measures a special mold is required and will only be made on special order. In ordering liners for a recessed mold you must be careful to specify “recessed mold” and the length in ems required. These molds can be applied to any model of machine, but must never be used for any size below 10-point.
