There are mainly two types of capsule filling machines: manual and automatic.

Manual capsule filling machines require the operator to manually fill each capsule with the desired substance using a tray and tamper. These machines are typically less expensive but can be time-consuming and require more labor.

Automatic capsule filling machines, on the other hand, are fully automated and can fill hundreds or thousands of capsules per hour. These machines use a variety of mechanisms to fill the capsules, including dosators, tamping pins, and vacuum-assisted filling. They are more expensive than manual machines but are more efficient and require less labor.

There are also semi-automatic capsule filling machines that combine aspects of both manual and automatic machines, allowing for faster and more efficient filling while still requiring some manual labor.
