Among the special materials in the packaging, we can refer to grease or similar products such as paste, sanitary creams, and various ointments. The filling mechanism in such materials is also different from other materials or liquids that are runny or thinner. The main difference between these devices is the drive to transfer materials to the feeding part.

The injection system in such materials is filling from the bottom of the container. Because this action causes the container to be completely filled and no bubbles are created inside the container. Adjusting the amount of material injection in the grease filling machine is in the form of timing, and the actuator valve is responsible for stopping and stopping the material flow. These machines are part of the family of thick liquid filling machines , which are produced semi-automatically.

The machine adopts piston pump and for filling. By adjusting the position pump, it can fill all of the bottles in one filling machine, with quick speed and high precision.
