Sonikel creates new projects for marine, sailing industry. Life jacket light includes 2 plastic parts. One is bottom side which holds electronic board and the second part is transparan top cover. These two plastic parts are polycarbonate and they should seal to each other without any leakage. Chemical is a solution but it is very time consuming so Ultrasonic welding again comes to scene. Sonikel made this Project and increased Production rate 5 times more. So Ultrasonic welding investment can tolerate itself in 4 months. At Sonikel R&D Department, we concentrate on innovative soluitons, from Turkey to all World.
