Precision welding and sealing: High-frequency ultrasonic vibration of 20-40KHz instantly generates frictional heat at the contact surface of the shell, achieving molecular-level fusion of the plastic and forming a seamless sealing structure at the joint after welding
Ultrasonic welding of printer toner cartridges
As core consumables for printers, the stability and lifespan of toner cartridges and ink cartridges are directly determined by the sealing of their casings and the precision of component assembly during the manufacturing process.
