Abstract
The invention relates to a process to manufacture an object using at least one granular material (16) having a large particle size, for example greater than or equal to 0.1 mm, such process being characterised by the following stages:the granular material or materials are placed in a mould (2) at the same dimensions as the object to be made and incorporating at least one evacuation opening (6), said opening being of a size that is less than the particle size of the material,a liquid-phase binder (21) is poured into the mould,the binder is mixed between the grains of material and the excess binder is drained off through the evacuation opening using suction means (11).Application in the manufacture of igniting tubes or propellant charges for artillery ammunition.
