Comparison between gravity filling machine and pressure filling machine
Aug 29, 2018

1. Working principle: gravity filling machine is relying on the gravity of materials, flowing from top to bottom to the filling head; pressure filling machine is to use the piston to extract the material into the cylinder, and then use the piston to inject the filling head for filling, just like a needle pipe injecting water after injecting the needle out of the needle, so the pressure filling machine is also known as the piston filling machine.

2. Applicable materials: According to the principle of gravity filling machine, it is suitable for water with good fluidity; and pressure filling machine is also suitable for high viscosity liquid and paste besides water agent, so pressure filling machine is also called high viscosity filling machine.

3. Price: The structure of gravity filling machine is simpler, the price is more cheaper; the structure of pressure filling machine is complex, and the price cost control is more expensive.
