Abstract

The control of the crimped closures sealing is a serious problem for the quality control of the producers using such closures. The sealing of this closure is ensured by the pressure of a seal-ring between the container and the crimped closure. The sealing quality depends on the applied materials, crimped force on the crimping machines and other settings. However the closing force on the sealing can not be controlled directly, just in an indirect way by measuring the torque of the crimped closures. During the research we have specified the connection between the crimp force, the remaining closing force after the relaxation and the measurable torque, and we have also developed the right instrumentation for the quality control of crimped closures.
