5.2. Semi-automatic Capsule Filling Machine

The semi-automatic capsule filling machine can also be called a multi-mold capsule filler, which is a combination of manual filler and mechanical power.

Structure of semi automatic capsule filling machine


The switching between each process of the semi-automatic capsule filling machine is done by hand. It contains the following workflow:

5.2.1. Capsule sowing and separating

The hard capsules in the hopper moves up and down with the capsule inserting plate, to enter the capsule sowing plate sequentially one by one and make the capsule stand upright, then turn around the capsule through the capsule inserting groove and fork. As a result, the capsule cap (upper) and body (lower) are fed into the mold hole of capsule sowing plate; which is separated by the negative air pressure below the lower die, so the cap is left in the upper die, and body in the lower die.

5.2.2. Powder filling

Transfer the separated capsule sowing lower die to the filling station, press 2 filling buttons of filling at the same time, the feeding port rotates to the die top, then the turbine rotates to fill the powder into the capsule body.


5.2.3. Capsule locking and discharge

After combining the upper and lower dies, placing them on the thimble tray, and pressing the two locking buttons at the same time, the machine will automatically complete the locking and discharge according to the set program.

The semi-automatic capsule filling machine described in this article is the latest machine of Migrand Machinery in 2024. If you are a professional, you must be able to understand its advantages. Welcome to read my other article - 2024 Comparison of New and Old Capsule Filling Machines.

Normally, the capacity of semi-automatic capsule filling machine is about 15000-25000 capsules per hour. A skilled operator can get the most out of the machine. For example, he can operate two or three sets of capsule plate at the same time, the capacity can even reach 30,000 capsules/hour. The capacity is surpassed that of the NJP-400 fully automatic capsule filling machine, while the price is only half of it.

Therefore, in a country with relatively low labor costs, I recommend a semi-automatic capsule filling machine to you.


In most cases, the semi-automatic capsule filler is only suitable for size 000-4# capsules. All these types of capsules can be produced on one machine, you only need to replace some necessary molds, as shown below:

A skilled operator can replace a set of mold within only 5 min. If you need, i can teach you how to replace the mold step by step.



5.3. Semi-automatic liquid capsule filling machine

As mentioned in the previous chapter, if the filling material is solvent, we call the machine “liquid capsule filling machine”, and the difference between it and the powder/granule capsule filling machine is mainly reflected in the filling station, as shown in the figure below:

The device on the right side is the liquid storage box and liquid filling system of the liquid capsule filling machine. After the capsule feeding into the mold and separating, through the filling station of the capsule filling machine to give the signal, the filling system quantitatively and accurately fills the liquid material into the capsule body in lower die according to the filling station signal. The subsequent processes, capsule locking and discharge, are exactly the same as the powder/granule capsule filler.


Maybe you think that the liquid capsule filling machine is very simple. Of course not! As for what machines are needed to cooperate with the liquid capsule filling machine to complete the whole production, I will elaborate in the automatic liquid capsule filling machine chapter, please continue to read below.
