The strapping head Unistrap with vibration welding is the evolution of the traditional system with electrical resistance; this system is the result of our technical research and experience of 20 years in the construction of automatic machines for the packaging of palletized units.
The vibration welding system (cold) was developed to improve the speed of the strapping cycle, and to avoid the smoke created by the traditional welding system with electrical resistance.
The maintenance of the strapping head with vibration welding is almost non-existent, as it’s built with mechanical parts of high precision hardened steel and without delicate components such as temperature detectors, resistors, etc.
