Ultrasonic Insert Welding is a commonly used assembly method for inserting metal inserts into a variety of plastics, post-moulding. It can prove more reliable than traditional heat inserting methods and often more cost effective than in-mould inserting.

Economical, reliable and easily automated, ultrasonic welding is a popular technique in the plastics welding industry. Ultrasonic welding differs from more traditional forms of welding, where heat is generated through contact with a direct heat source.

There are three distinct types of plastics which respond to ultrasonic welding in different ways: thermoplastics, elastomers and resins.

Plastic welding is the process of making a molecular bond between two thermoplastics that are compatible, which when cooled return to a solid form.

One straight forward process for doing this is ultrasonic plastic welding. Whatever the specifics of a particular application, ultrasonic welding's fundamentals always remain the same, employing sound waves that are ultra-high in frequency, plastic can be heated with the ensuing friction, creating a strong bond.

Ultrasonic welding offers your company a fast, reliable way to join many materials. This process has many advantages over other bonding methods, and is extremely safe. At Xfurth we have decades of experience with state of the art welding technologies. We want to share some of the advantages that ultrasonic welding can give you, so you can decide if it is the right plastics welding technology for your company to invest in. Let’s have a look at some of the ways that ultrasonic welding can offer you manufacturing advantages, and the applications where it performs well.
