1. Working principle: Atmospheric pressure filling machine relies on the gravity of the material and flows from the top to the filling head; injection pressure filling machine uses the piston to pump the material to the cylinder, and then uses the piston to inject the filling head for filling , Just like a syringe needle pumping medicine after injecting the needle, so the injection pressure filling machine is also called piston filling machine
2. Applicable materials: According to the principle of atmospheric pressure filling machine, it is suitable for liquids with good fluidity; in addition to liquid agents, injection filling machines are also suitable for high viscosity liquids and pastes, so injection pressure filling High viscosity filling machine
3. Price: The structure of the normal pressure filling machine is simpler and the price is flat; the structure of the injection pressure filling machine is complicated, and the price and cost are controlled by many workers. Please contact us for more prices.
