Spin welding is a process that joins circular thermoplastic parts by bringing the part interfaces together, under pressure, with a circular, spinning motion. One part is held stationary in a fixture, while the other is rotated against it under pressure. The frictional heat that is generated causes the part interfaces to melt and fuse together, creating a strong, hermetic seal. Our engineering staff will work closely with you to help you with your spin welding application. This includes determining the speed of part rotation and appropriate pressure of the driver as the parts are spun together.
