A heating and air conditioning car dashboard control display unit had to be assembled to very high standards. It had to be strong and durable. The goal was achieved by using an ultrasonic welding technique which provides a joint that is stronger than the surrounding plastic.

Forward Technology Industry developed a twin headed machine so the welding operation could be completed from a rotary table by two separate welding processes. The first fixes two spring clips that activate the on/off switches of the unit by riveting four Polycarbonate pegs. The second head fixes a light guide and filter by riveting six pegs. The machine produces 360 units every hour.
