For joining complex injection moulded plastic medical parts, ultrasonic welding is an ideal solution.

At Mi3, we offer the very best in ultrasonic welding –from equipment to technique – ensuring your device meets and exceeds both quality and cost requirements.

Ultrasonic welding is particularly well suited for bonding medical devices since it uses the device material itself to form the bond. Hence, it does not introduce any glue or adhesive into the device that could form toxicity issues. Ultrasonic welding is a fast, clean, efficient and repeatable process.

At Mi3, our technical team work with you closely to select a material suitable for your device that is readily weldable. We can help with developing the joint and optimising the welding process to ensure the process is controlled from start to finish.

What is Ultrasonic Welding?

Ultrasonic welding plastics is much faster than using conventional adhesives or solvents. The drying time is very quick and hence reduces the time needed to dry or cure. Ultrasonic plastic welding can be easily automated, making for clean and precise joint and the low thermal impact on plastics enables a greater number of materials can be welded together.

“Mi3 has a customer focus culture and it is dedicated to helping solve issues and improve output quality. Medela AG has seen how Mi3 is passionate about assisting us to scale up the business”.

Meeting Exacting Specifications

Mi3’s ultrasonic welding equipment can be easily customised to fit the exact customer specifications for the laser welding of medical devices. Our laser welding equipment is installed within our class 8 cleanroom which allows components to be securely welded within a clean room environment, before moving seamlessly on into the assembly and packaging processes of the manufacture.

Quality In, Costs Out

Ultrasonic welding can be used with both hard and soft plastics.  At Mi3, we offer a variety of other welding and assembly processes, in line with the particular requirements for your device. Our material and process expertise will help us to design devices that ensure quality’s in, and costs are out.
