A hand mould is a simple mould used for low quantity work. It is used in the injection moulding and the printing industry.

In the printing industry, a hand mould specifically refers to a two-part mould used for casting hand-made type. Inside the mould is a matrix.

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).

In this method, the type was made by punching a letter-shaped cavity in a matrix made of some soft metal (typically copper). Then this matrix would be held in the lower part of the mould, the upper part would close on it, and molten type metal would be poured into the cavity. Using the hand mould, the printer could quickly make any additional type he might need.

In injection moulding, hand moulds refer to simple moulds that have no provision for heat, cooling, or ejection. This means when a hand mould is cycled universal heating plates are required to warm the moulds and the moulds must be removed after each cycle to remove the mouldings. This drastically increases the cycle time, which limits it to short runs, but to offset this is the low cost of the mould. They are usually single cavity moulds, but may be multi-cavity if the moulding is quite small. They are usually only of a two or three plate design because of the simplicity of the parts. If only a short run is required then the moulds may be made from aluminum or brass, but if more parts are required then they are made from conventional steels.
