Ultrasonic welding is one of the fastest and cleanest ways to join injection-moulded plastic parts. In this video, we break down how component design, energy directors, shear joints, and welding parameters like amplitude, pressure, and weld time directly affect weld strength and quality. Learn the difference between near-field and far-field welding, why sharp corners should be avoided, and how proper design leads to consistent, reliable plastic welds. Perfect for engineers, welders, and manufact
