1. Understanding Automatic Ultrasonic Riveting Machines

An Automatic Ultrasonic Riveting Machine is an advanced assembly system that uses high-frequency ultrasonic vibrations to deform and bond thermoplastic components. Unlike mechanical fastening or adhesive bonding, ultrasonic riveting relies on frictional heat generated by ultrasonic energy to soften plastic rivet points and form strong, permanent joints.

Automation plays a crucial role by integrating programmable logic controllers (PLC), servo systems, and intelligent sensors. Companies like Desheng design automatic ultrasonic riveting machines to seamlessly fit into high-volume production lines, ensuring repeatability, precision, and minimal human intervention.

2. How Ultrasonic Riveting Technology Works

Ultrasonic riveting technology converts electrical energy into high-frequency mechanical vibrations. These vibrations are transmitted through a horn (sonotrode) to the plastic rivet, causing localized heating and controlled deformation.

Basic Working Process

1. Plastic components are positioned in a fixture.
2. The ultrasonic horn contacts the plastic rivet post.
3. Ultrasonic vibrations soften the plastic.
4. The rivet head forms under controlled pressure.
5. The material cools, creating a strong joint.

3. Key Ways Automatic Ultrasonic Riveting Improves Efficiency

3.1 Faster Cycle Times

Automatic ultrasonic riveting machines dramatically reduce cycle times compared to manual or semi-automatic methods. Each riveting operation typically takes only a few seconds, allowing manufacturers to achieve high throughput without compromising quality.

3.2 Consistent and Repeatable Quality

• Precise control of amplitude, pressure, and time
• Reduced risk of under- or over-riveting
• Stable joint strength across batches

3.3 Reduced Labor Costs

Automation minimizes manual handling and operator dependency. One operator can oversee multiple machines, significantly lowering labor costs while improving production efficiency.

3.4 Lower Scrap and Rework Rates

By maintaining consistent process parameters, automatic ultrasonic riveting machines reduce defects such as cracked parts or weak joints, leading to less scrap and rework.
