Spin plastic welding machines
JSB Ultrasonic’s Spin Plastic Welding Machines use rotational friction welding to join circular thermoplastic components — an ideal process for round parts where ultrasonic welding’s vibration pattern isn’t the best fit. Available in automatic and servo-controlled configurations, our spin welders deliver strong, consistent, leak-proof circular welds for high-volume production.
Spin welding is widely used wherever two round plastic halves need to be joined into a single, sealed component — from fluid reservoirs and filter housings to caps, closures, and cylindrical enclosures.
What is a Spin Plastic Welding Machine?
A spin welding machine rotates one plastic component at high speed against a stationary mating part under pressure, generating frictional heat at the joint interface. Once the interface reaches melting point, rotation stops and the parts are held under pressure to fuse and solidify into a single, permanent bond — producing a strong, hermetic seal without adhesives or fasteners.

Frequently Asked Questions
What parts are best suited to spin welding?
Spin welding works best on round or cylindrical plastic components — reservoirs, caps, filter housings, and similar circular parts.
Can spin welding produce a hermetic seal?
Yes, properly tuned spin welding produces strong, leak-proof, hermetic seals suitable for fluid-carrying components.
What is the difference between spin welding and ultrasonic welding?
Spin welding uses rotational friction and is best for round parts, while ultrasonic welding uses high-frequency vibration and suits a wider range of joint shapes.
Do you provide installation and training?
Yes, installation support and operator training are included so you can get the machine running correctly from day one.
Do you offer customization?
Yes, our engineers can review your part or application and recommend a customized fixture, horn, or configuration.
What after-sales support is available?
We provide spare parts, preventive maintenance guidance, and remote or on-site troubleshooting support for the life of the machine.
