Hand mould

[1] In particular, it refers to a system for casting movable type, pioneered by Johannes Gutenberg, which was widely used in the early era of printing in Europe (15th-16th century).

Using the hand mold, the printer could quickly make any additional type he might need.

This drastically increases the cycle time, which limits it to short runs, but to offset this is the low cost of the mold.

[3] Hand cast bullets remain popular with the handloading, muzzleloading and small custom ammunition loading communities.

As the blocks are now usually made out of aluminum, which does not allow lead alloys to stick, only a small amount of parting compound is needed.
