Ultrasonic Welding Services at A6 Mouldings

Ultrasonic welding is an industrial technique whereby high-frequency ultrasonic acoustic vibrations are locally applied to workpieces being held together under pressure to create a solid-state weld. It is commonly used for plastics, and especially for joining dissimilar materials. In ultrasonic welding, there are no connective bolts, nails, soldering materials, or adhesives necessary to bind the materials together.

Contact A6 Mouldings via our contact form or call us on 01536 410794 to discuss your plastics manufacturing requirements.

We perform Ultrasonic Welding Services via our Manufacturing plant right here in the UK, based in Kettering, Northamptonshire. Our designers will help you to design, prototype and produce your plastic products.

Review our handy guide below which lists the most common unfilled grades of plastic available & their suitability for each style of ultrasonic welding. If you have any questions, contact us directly.

We can work with you to create a design for your plastics product and ensure we deliver on time and on budget, the right solution to suit your requirements.

A (Amorphous)Polymers with a random molecular chain structure. This & their wide softening temperature range enables them to soften gradually without solidifying quickly, thus making ultrasonic welding them easy.
C (Crystalline)polymers with an orderly molecular chain structure. This & their sharp melting & solidification points makes them absorb vibrations when solid, thus making ultrasonic welding them more difficult.
Close Weldingultrasonic welding where the horn is applied close to (<6.35mm) the assembly joint - good for welding materials whose low modulus of rigidity dampens vibrations a short distance away from the horn
Distant Weldingultrasonic welding where the horn is applied away from (>6.35mm) the assembly joint - good for welding materials whose high modulus of elasticity propagates vibrations without dampening them
Insertingultrasonic embedding of metal components like inserts into preformed holes in the moulding - provides high strength & speed, no stress build up & reduced moulding cycles
Spot Weldingultrasonic assembly of parts without premade holes or energy directors - good for large parts
Stakingmelting and reforming a post on the moulding to mechanically lock dissimilar materials in place - provides short cycles, good appearance & tight assemblies
