FIELD: process engineering.
SUBSTANCE: invention relates to extruders of energy-bearing materials and may be used for making pyrotechnical cords from pre-compacted pellets. Proposed device comprises container with central guide channel and blind spline. Male die is arranged coaxially in said container. Reducing female die with through forming orifice adjoins the container end. Detachable ring is provided for geometrical closure of container with female die. Replaceable cardboard tube is fitted coaxially in container blind axial groove for gapless fitting of preformed pellet in press toolage axis.
EFFECT: higher quality of extruded articles and safety in extruding energy-bearing pyrotechnical materials.
