Handheld Ultrasonic Welder Realizes Stable Riveting for Auto Door Inner Plastic Posts
Published On: June 2, 2026
This North American auto parts factory produces car door inner plastic trim parts, which need fixed plastic stud riveting. Traditional hot nail welding easily causes post melting collapse and poor bonding consistency.
Our handheld ultrasonic plastic welder completes point riveting on small plastic pillars precisely. Controlled vibration heat avoids over-melting, ensuring tight combination between plastic posts and shell. After mass application, product reject rate dropped below 2%, production efficiency increased 32%, and the client signed long-term annual procurement contract.
