ultrasonic welding fixture and horn

Sometimes the design of a component will be too complex or expensive to be moulded in an injection mould tool.  Often this requires components to be joined together post moulding.

Our aim is to provide our customers with as finished a component as possible, reducing the additional costs of secondary operation and transport between subcontractors.  Therefore in addition to our assembly services, we offer Ultrasonic welding which depending on the plastic provides a strong and permanent bond between parts.

Ultrasonic welding is a technique whereby high-frequency ultrasonic acoustic vibrations are locally applied to components.  The friction created by this vibration under pressure, melts the plastic at the meeting point that when cooled creates a solid state weld.
