Abstract
An apparatus for producing a shaped part has a shot sleeve. A melt can be fed into the shot sleeve. The melt can be forced into a die by means of an injection plunger. The apparatus is provided with a drive unit for actuating the plunger rod. Moreover, the apparatus has an oscillation generator, by means of which the plunger rod can be set in longitudinal oscillations. The plunger rod is moveably connected to the drive unit.
Claims18
Apparatus for producing shaped parts, said apparatus comprising
- a shot sleeve into which a melt can be fed,
- an injection plunger for forcing the melt into a die,
- a plunger rod for the injection plunger,
- a drive unit for actuating the injection plunger, and at least one oscillation generator,
- by means of which the plunger rod can be reciprocated along its longitudinal axis,
- wherein that the plunger rod is moveably connected or connectable to the drive unit.

Process for producing a shaped part comprising the steps of
- introducing a melt into a shot sleeve,
- forcing the melt into a die by means of an injection plunger,
- moving the melt out of the shot sleeve in the direction of the die in a movement phase, and forcing the melt into the die with pressure in a shot phase,
- wherein the injection plunger or a plunger rod which holds the injection plunger is subjected to reciprocation along its longitudinal axis during the movement phase.
