Linear vibration welding physically moves one of two parts horizontally under pressure, creating heat through surface friction that melts and welds the parts together. Compared to ultrasonic welding, vibration welders operate at much lower frequencies, higher amplitudes and much greater clamping force. Linear vibration welding is designed with electromagnetic heads that eliminate the wear and lubrication associated with bearing surfaces.
Vibration welding can join all known thermoplastics including materials with up to 45 percent filler content. Vibration welders can also join many dissimilar materials with compatible melting points, composite materials and fabrics. The following materials may be assembled by vibration welders: amorphous resins such as ABS/PC, PVC, PMMA or PES; semi-crystallines such as HDPE, PA, PP and TEO. Vibration welders can also join fiber reinforced carriers such as wood fiber, textile fiber or Polyurethane Long Fiber directly or by claw effect, or with composite surface coating.
