Abstract
A system and a method for a constant micro dosing of powder material include a control device, a cylinder with a first opening and a piston movably arranged inside the cylinder and controllable by the control device. The piston is movable in the direction to or away from the first opening along a piston stroke direction. The cylinder stores the powder material between the piston and the first opening. The piston pushes the powder material through the first opening by moving along the piston stroke direction. Further the system and the method include a removing device for removing the powder material which is pushed out of the first opening of the cylinder. The control device controls the piston and the removing device in a synchronized manner such that a predetermined amount of powder material pushed through the first opening is removable by the removing device.
