The invention relates to a method of producing metal mould cavities by means of ceramic and metal powder sintering. According to the invention, once a ceramic powder has been selected from those available on the market in accordance with the production parameters, the inventive method comprises: a first step consisting in sintering the powder using a laser such as to produce a template ( 7, 8 ) which can be used directly, without any treatment, in the second step; and a second step consisting in pouring the metal powder around the template and sintering same in a furnace. The aforementioned method can be performed very quickly and cost effectively. The invention is particularly suitable for use in the production of cavities which are intended for gravity moulding or low- or high-pressure injection moulding.
