Mecmesin world leader in Closure Testing

A manufacturer of smoke grenades required a means of testing the cap pull-off strength, especially gripping the smooth metal cylinder for up to the maximum value of pulling force. An annular clamp would be needed with penetrating pins to hold the cannister, and in alignment with the applied load. A four-way grip was designed and manufactured by Mecmesin engineers, with pins penetrating the canister base. This provided a secure and symmetrical grip, whilst pulling the rigid cap off with hooks applied to the two cap holes to measure the peak force applied.
