In food industry chemical agents are not used while assembling plastic parts. Another method to combine plastics into each other is ultrasonic sealing. Sonikel Ultrasonics, provides customized solutions for food industry. In summer time, ice cream has been eaten so many times so production is being increased. To seal the plastic small spoon in the cap of ice cream container, ultrasonic welding machine is used. By integrating ultrasonic equipment into an automation system, ultrasonic welding creates a very big production performance. In this application, sealing level is very important. If you give more ultrasonic vibrations than needed, the user can not take the small spoon from the cover of the plastic cup. If you give less ultrasound energy than needed, the spoon will drop on the ice cream. So the ultrasonic welding energy should be adjusted very well in this application. Sonikel cooperates with the machinery manufacturers and automation companies from the begining of the Project till the end of it. Sonikel Ultrasonics, designs and manufacture application specific sonotrode and fixing apparatus from alumium and titanium.
