In the production of the automotive industry, component welding is a key link. There are more and more plastic components in automobiles. The effect of plastic welding determines the final quality of automotive. Auto parts and body structure specifications require high precision and high performance. Ultrasonic plastic welding, as an efficient, economical, environmentally friendly, and good sealing solution is fully capable of this complex task.
In addition, with the rapid development of lightweight and new energy automotive, ultrasonic metal welding technology is widely used in the automotive industry.
Functional Components Ultrasonic Welding
The welding of functional components requires that the functions are complete and unrestricted. Ultrasonic welding machines from Knmtech provide fine welding parameter settings to ensure high-precision welding process control.
Exterior and Lights Ultrasonic Welding (7)
Ultrasonic plastic welding is economical, fast, and reliable, and is increasingly favored by the automotive manufacturing industry, where high strength, tightness, and dimensional accuracy, along with a scratch-free and indent-free appearance, are typical requirements. Ultrasonic welding protects the function of components and enables the welding of complex shapes.
Interior Ultrasonic Welding (6)
Commonly used plastic connection methods include fasteners such as screws and snaps, as well as vibration friction welding and ultrasonic welding. Among them, screws, snaps, etc. are simple in connection and low in cost. They are common applications. Vibration friction welding and ultrasonic piercing welding have high costs and require corresponding development equipment. Ultrasonic plastic welding can save space and has high efficiency. The application of ultrasonic welding of plastic parts is increasingly widespread.
Drive Components Ultrasonic Welding
The soft pack battery has the advantages of high energy density, strong safety, flexible layout, and long cycle life. Ultrasonic metal welding can be used for the tab welding of the soft pack battery. Ultrasonic welding makes the metal melt and bond, and it is very strong. Copper, aluminum, and nickel can be welded.
Compared with the traditional wire harness tin welding, ultrasonic wire harness metal welding has unique characteristics: it does not change the characteristics of the metal itself, does not need to be immersed in acid water, and does not need solder. Wire can be welded and formed at one time, the tensile force can reach 80% of the body.
Power battery module copper and aluminum bar ultrasonic metal welding is fast, energy saving, high stability, and close to cold working. The welded product has good fusion, low internal resistance, high strength, good electrical conductivity, and no sparks.
