The invention relates to a molding tool and to a method of tempering a molding tool intended for the manufacture of objects from moldable material. The tool is comprised of at least two mold parts (1, 2) which delimit a mold cavity (3) when the mold is closed. The tool includes at least one sintered metal mold part (6, 7) having communicating pores. The mold parts include a plurality of mutually joined, sintered metal units (6A, 7A; 6B, 7B...) that include communicating pores. The outer mantle surface of the porous unit is impervious and the area that faces towards the cavity (3) has open or closed pores. Each porous unit includes fluid delivery and fluid discharge means. The method is characterized by tempering each mold unit independently of other mold units.
