Stuck in the Ultrasonic Welding Weeds? 

Ultrasonic welding of plastic materials creates a molecular bond within the weld joint when vibration at high frequency is introduced into plastic under force. We understand you want to nail down the right welding systems to launch your products successfully. You need to know that our ultrasonic plastic welding machines and automation systems will be delivered on time and function flawlessly. And you want the systems in your plant to be backed by customer support that covers every shift, every day.

Let AMS handle your plastic assembly needs:

  • Deep application knowledge
  • 99.5% on-time delivery record and 97% customer satisfaction
  • 24/7 hotline for urgent support
  • Flexible “engineering only” option

Plastic Assembly Systems from AMS

AMS can reliably join your plastic parts to meet even the toughest requirements. Our capabilities include:


Ultrasonic plastic welding uses high-frequency mechanical vibrations transmitted through thermoplastic parts to create frictional heat at a joint interface. The frictional heat generated causes the part interfaces to melt and fuse while pressure is applied. This technique is fast, efficient, non-contaminating and requires no consumables.

AMS will help you obtain repeatable ultrasonically welded results by working closely with you to create the best joint design for your application. We will also assist you in analyzing the welding characteristics of thermoplastics as well as an understanding of how polymer structure and other factors affect the weldability of various polymers (including polymer structure, melt temperature, melt index, modulus of elasticity, and chemical makeup). Our engineering team will ensure that you get the results you are looking for.

Thermal plastic staking

Ultrasonic plastic staking

SPIN welding


As with ultrasonic plastic welding and spin welding, ultrasonic spot welding joins together similar thermoplastic components without damaging their structure. The welding tip vibrates ultrasonically when passing through the materials, producing frictional heat as well as a void through which the melted plastic can flow between the parts, thereby fusing them together.


Ultrasonic welding can generally produce a strong, durable weld in less than one second. Molded joints, screws, and rivets aren’t needed and this method is compatible with almost any thermoplastic

Textile welding

Increase Productivity and Efficiency with Plastic Assembly Operations

To get ahead, you need to increase throughput, minimize handling and improve quality. Automating your plastics assembly gives you the competitive edge. And while we offer standard ultrasonic welding machines, spot welding, staking, textile welding and more, our engineers are experts at customizing systems to our customers’ exact application needs.
