A process for producing mouldings, especially chemical or pharmaceutical material mouldings, comprises mixing the active material and the additive in a worm-cylinder unit, and then injection moulding the material. The material is injected into a number of separate moulds. The worm cylinder unit has a supply point for the active material, and an intermittently operating injection unit. A process for producing mouldings, especially chemical or pharmaceutical material mouldings, comprises mixing the active material and the additive in a worm-cylinder unit, and then injection moulding the material. The material is injected into a number of separate moulds. The worm cylinder unit has a supply point for the active material, and an intermittently operating injection unit. The extruder has a double shaft. The extruder (10) operates continuously, and the injection unit (20,30) operates intermittently. The material is collected in an inner chamber (24,34) and fed to a nozzle (46) via injection channels (42,44).
