How to Apply the Correct Amount of Torque onto your Caps

A cap is properly sealed when the contents within the container cannot leak out and substances outside of the container cannot enter in. In addition, the end user must be able to open the container with a reasonable amount of effort; it should not be too difficult to open.

Many manufactures rely on this intuition when determining how tight their caps should be. If your caps seem appropriately tight, and you have not had issues with leaking bottles, then it is usually fine to continue to use an intuitive approach when capping your bottles.

For various reasons, such as internal quality controls, or industry or government regulations, many bottlers must validate the amount of torque they are applying to their caps. When this is the case, the first step in the process is to determine how much torque your cap requires.

Our servo capping machine can control the torque very well, and the precise precision control will not make the cap screw too tight or too loose, completely according to your set value.
