There are usually different filling types according to different filling standards.

According to the degree of automation, the types of filling machines are: manual filling machines, semi-automatic filling machines, and fully automatic filling machines.

Manual Filling Machines

These are manually operated and will need no power or electrical source. They are generally used for packing highly viscous liquids like creams, gels, and shampoos but will also suffice for medium viscosity liquids. Manual filling machines are ideal for small scale productions or laboratories where they will provide a higher output speed and increased accuracy than when the liquids are poured by hand. They are ideally used for filling vial and bottles with about 600ml capacities and have a production speed of 15-900 bottles/hour. This type of machine is not produced by NPACK.

Semi-Automatic Filling Machines

These will be faster compared to manual machines and will suit medium and small scale production processes during a high-volume season. Semi-automatic machines are designed with nozzle, syringe and piston parts which guarantee they maintain a zero-drip operation. They can be used to package all types of liquids and those containing small food articles and even adhesives. Semi-automatic machines have filling ranges of 5-100ml and production speeds of 800 fills/hour.
