PROCESS TO MANUFACTURE AN OBJECT USING A GRANULAR MATERIAL IGNITER TUBE AND PROPELLANT CHARGE OBTAINED USING SUCH A PROCESS

摘要

Tie 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 m, such process being characterised by the following stages: ;the granular material or materials are placed in a mold (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 mold, ;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.
