Child resistant closures (CRC) mandrel

Customised engineering example

Child Resistant Closures (CRC) require sufficient vertical force to activate the CR locking mechanism prior to torque being applied.


Testing the removal, retention or reverse-ratchet torques is best achieved by using Mecmesin motorised torque testers, the Vortex and Helixa. They allow you to apply torque at a constant speed in accordance with international and industry standards.  Obtaining the most reliable and repeatable test results is attained by using a custom-profiled mandrel for the cap. This avoids distorting the closure which would affect the torque readings.


Mecmesin regularly design and provide custom mandrels, especially to the pharmaceuticals packaging sector. Contact us with your requirements for a quick response towards improved testing.
