Mondial distributes Warner Electric magnetic screwing heads, for the automatic application of pre-threaded plastic caps on PET and PVC bottles, adopted by important mineral water brands. The main characteristic is the interchangeability with the main models of the original producers. Consequently, no modifications on the pre-existing equipment are necessary. The magnetic screwing heads are made with the constant coupling Smooth Torque technique, which eliminates the problem of the excessive tightening of the caps. The constant coupling of the Warner heads solicits the plant less than the pulsating torque heads and, consequently increases the duration of the components of the machine and especially of the sealing blades. Efficiency, longer operating life, minor functioning costs, easy to regulate and easy to maintain are the strengths of a product that in the United States is installed in the Coca Cola, Pepsi Cola and Nestlé factories.
