Ultrasonic Welding

We have been providing ultrasonic welding services in-house for over 15 years and have built up a lot of experience with the process. Ultrasonic welding is the ideal solution for joining plastic injection moulded parts together.

Ultrasonic welding is a great process which creates strong and very neat weld seams without the use of solvents, adhesives or external heat. It is a very popular choice for joining plastic injection moulded parts together to create a strong finished product, which is why as a plastic injection moulding company we have chosen to specialise in this welding technique.


Our Ultrasonic Welding Facilities

Our ultrasonic plastic welding facilities include 4 ultrasonic welding machines. Three of our machines have a 1500-Watt capacity and our newest ultrasonic welding machine has a capacity to 4000 Watts which allows us to weld large areas requiring high power.

If you are looking to create a product made up of various plastic injection moulded parts then ultrasonic welding could be a really good option.

Please get in touch with us to find out more about our ultrasonic welding services.



What is Ultrasonic Plastic Welding?

Ultrasonic welding uses high-frequency sound waves and pressure to bond plastics together to create a fully assembled product. The high frequency vibrations generate heat energy between the two parts which causes the materials to melt and bond with each other. This creates a very strong weld between the two pieces of plastic once cooled.

Ultrasonic assembly is widely accepted and is used in many industries including: automotive, medical, electrical and electronic, communications, appliance, consumer products, toys, textile and packaging. It is an economical process that can significantly increase production and lower assembly costs.


Ultrasonic Welding Advantages

There are many advantages to using ultrasonic welding for your product assembly. It is a fast, clean, efficient and repeatable process that produces strong, integral bonds between plastic parts whilst consuming very little energy. Other advantages include:

  • No solvents, adhesives, mechanical fasteners or external heat is required.
  • The finished welded assembly is very strong and clean.
  • Great for assembling difficult materials.
  • Part assemblies are cycled quickly, the energy transferred to the joint is released as heat very rapidly and is confined to the immediate joint area. The rapid dissipation of heat makes the ultrasonic welding process considerably faster than other methods of assembly.
  • An ultrasonic assembly system’s tooling and/or application can be quickly changed. This offers flexibility and versatility not found in many other assembly processes.
  • The relatively low-cost investment in ultrasonic equipment vs. its high reliability, long life, and consistent, repeatable performance, makes ultrasonic welding the preferred method of assembly.

Whilst ultrasonic welding might not be appropriate for all material types and thicker dimensions, it is great for many applications especially for joining plastic injection moulded products.
