Pre-loaded Ultrasonic Unit Saves Time in Automation

Compact ultrasonic actuators with low weight can be easily mounted on robot arms and are thus well suited for fast and low-energy joining of plastic parts. Pre-loading the pneumatic cylinder of the actuator saves time – up to 1 second per weld spot. This is particularly noticeable in applications with many weld spots. Pre-loading means [Read More]

Flawless 3-D lights

Daytime running lights have become mandatory by EU Standards as of recently and are a popular style element. Their complex 3-D shape represents a challenge for joining technology. The ultrasonic welding tool can be easily adapted to the design type by means of studs in various heights. Short cycle times and indexed tool change kits [Read More]


Tips on Using Ultrasonic Welding within an Automation Process

Natasha Townsend, Associate Editor Despite the higher initial investment, the speed of ultrasonic welding as a joining process makes it an attractive process during automated production. During the process, ultrasonic vibrations generated through the use of electrical voltage melt the plastic material precisely at a defined joining point or area and create a homogeneous connection.
