Top 4 Reasons Why Your Cap Chuck Isn’t Stalling

Are you using a precise target removal torque and noticing that your cap chuck failed to stall during cap application? There may be underlying issues that need to be addressed. Many companies use very precise target removal torque for several reasons. Using precise target removal torque not only prevents the end user from struggling to open the bottle, but it guarantees a safe product for the user to consume. There are many benefits to the use of precise target removal torque. However, it is important to keep in mind the challenges that may come when used in the capping process. At Precision Tork, we want to ensure that your company is well-prepared to face these challenges accordingly.

One of the most common challenges while using precise target removal torque is ensuring that the capping equipment is properly configured. If you are using magnetic headsets, one major indicator that your equipment is not properly configured is the cap chuck failing to stall during cap application. When the cap chuck is not stalling, there are several factors that could be contributing to this, including:

1. There is not enough headrise. When there is not enough headrise, the headset will not be able to reach the target top load. Not having proper top load allows potential for the bottle to spin, which prevents the caps from stalling. The recommended headrise on a headset is typically between 2.5 to 5 millimeters.
2. The knives have become dull. When the knives are dull, they cannot obtain a firm grasp on the bottle. The bottle will spin as the headset is trying to torque the cap onto the bottle. Knives will dull over time, so it is crucial to consistently check the quality and make replacements when necessary.
3. The caps are spinning in the chucks during cap application. When the caps are spinning in the chucks, the headset will not be able to apply the proper torque. This is a common sign that the chucks have worn down and require maintenance.
4. The top load needs to be configured. When there is not enough top load, the knives may not be able to hold the bottle in place even when sharp. This issue can cause new knives to wear out very quickly due to the bottles spinning on the knives and grinding the interfacing points downward. The top load can be measured at headrise deflection, which is typically measured at 35-45 pounds. However, more load may be required for glass bottles.
