    25.How to Troubleshoot Common Problems of Automatic Capsule Filling Machine?

    Some common problems may occur during the Capsule filling that you must know and ready to find their remedies.

    1- Capsule not Entering the filling place

    This type of error/problem can be occurred due to some technical issues in the Machine.

    • There is a small part in the machine called the Baffle plate which maybe not be set properly after pulling out the capsules.
    • The filling place of the machine may be damaged.
    • The slow speed of the machine can also cause a problem.
    • Maybe some dust particles or other foreign particles are inside the magazine.


    Set the Baffle plate properly so the flow of the capsules can not be stopped and the magazine can load them properly.

    Before starting the Capsule filling see if the magazine is damaged then replace it.Because the damaged magazine will affect the smoothness.

    In the ideal state, machines are used at high speed when the speed is below 50-60spm while in general use then this problem may appear. Try to use the machine at high speed.

    If there are some other particles present in the magazine use compressed air pressure to remove them.

    2- Capsule getting Damage

    During the filling, the capsule may get damage this happened because the rectifier block is not aligned properly.

    Rectifier alignment with body bushes or cap bushes can cause this type of problem.

    Damaged capsule

    Damaged capsule


    The solution is easy to do check the rectifier is aligned perfectly and remain in touch with the cap bush if not try to align them properly.

    3- Loss of Cap during Transfer

    This problem can occur due to two reasons during the capsule filling process.

    • High vacuum inside the machine.
    • Miss Alignment of cap and body bush.

    High vacuum power sometimes can cause the loss of cap in capsule filling to try to use the moderate value of vacuum with the help of throttle.

    Before capsule filling check the alignment visually between cap and body bush. Do this by using the given alignment gauge.

    4- Capsule not Separating

    Here, are some problems that can work against the separation of capsules.

    • Leakage through the Filters
    • Worn out bushes
    • Loss in the Spring extension


    If the vacuum is decreasing slowly there will be some leakage in the filters of the vacuum. Try to remove the vacuum or replace it.

    When the capsules get stuck in the bushes try to clean the bushes and if the cleaning does not work then try to remove the specific bushes.

    Poor spring extension on the top slider will defect the separation try to replace those poor spring extensions.

    5- Weight of Capsule not achieved as per your need

    • Size of the capsule smaller/larger
    • Binding is not appropriate
    • Poor flow of filling product


    Always check the variations and parameters of the capsule that how much it can hold inside with which intensity.

    What type of capsule you are using for what type of filling material like, powder, pellets, or liquid.

    Form the slug properly to get the precise quantity of filling product before the binding is done. If the slug is not formed perfectly some of the material will lose and will affect the weight of the capsule.

    Check the flow of product according to the filling speed of the machine or the filling product is coming in the desired quantity and see the output is good or not. If not try to adjust the flow of filling product.

    6- Disturbed Weight Variations

    Three major variations can cause this type of problem in capsule filling.

    • The gap between dosing disc and wiper block.
    • The maintenance level of body bush and tamping pin.
    • The gap between the dosing disc and supporting pad.
    • The maintenance level of body bush and dosing disc.
