20kHz 2000watt Ultrasonic Welding System Applied to Mask Making Machine
Ultrasonic welding is the joining or reforming of thermoplastics through the use of heat generated from high-frequency mechanical motion. It is accomplished by converting high-frequency electrical energy into high-frequency mechanical motion. That mechanical motion, along with applied force, creates frictional heat at the plastic components' mating surfaces (joint area) so the plastic material melts and forms a molecular bond between the parts.
The tools and applications of the ultrasonic assembly system can be changed quickly, thereby providing flexibility and versatility not found in many other assembly processes. In addition, relative to the low-cost investment of ultrasonic equipment and its high reliability, long life and consistent, repeatable performance, ultrasonic welding has become the preferred method of assembly. Ultrasonic assembly has been widely accepted and used in the automotive, medical, electrical and electronic, communications, home appliances, consumer goods, toys, textile and packaging industries. This is an economical process that can significantly increase production and reduce assembly costs. Ultrasonic welding machines can be easily integrated into automated manufacturing environments, and the 100% full electrical control of the latest equipment provides unprecedented repeatability, reliability and accuracy for the process.
