What is Spin Welding?

The process of spin welding uses heat generated by rotational friction at the joint line to weld thermoplastic parts with rotationally symmetric joints. The spin welding machine applies pressure axially while rotating one part against its stationary mate, and the resulting friction generates heat that melts the parts together.

Advantages of the spin welding process include high quality permanent joints, hermetic seals, lower equipment costs, ease of assembly, energy efficient operation, no ventilation required, immediate handling, entrapment of other parts, far-field welding capability and no additional material requirements.
