Orientation Spin Welding or Servo Drive Spin Welding has several additional benefits over Inertial Spin Welding. The main benefit is the ability to stop the part being welded at a specific point during its 360 degrees of rotation and index to a specific spot with respect to the mating part with an accuracy of ±1°. Also this indexing is available at both ends of the stroke. At the head up position, the driver can be rotated to any position for loading purposes or part pick up, making it ideal for automation applications.
Another benefit of Orientation Spin Welding is that there is no need to store energy or inertia in a spinning flywheel because of the torque generated by the servo drive motor. So it is possible to contact the part with the driver and to apply pressure to the part before rotation begins to either compress or align the two mating parts before welding. Therefore, the circumference speed calculations found in Inertial Spin Welding do not apply to Orientation (Servo) Spin Welding.
With orientation spin welding applications it is also important to have the appropriate conditions for spin welding success along with sturdy driving features to allow for proper orientation.
|Head Down:||Upper spin driver moves downward (typically without rotation) until the part halves make contact.|
|Spin:||Upon contact, a slight delay occurs to insure parts are seated properly and rotation is maintained at the user programmed RPM until the programmed number of revolutions and final axis of rotation (degrees) of the weld is achieved. If orientation is not required, user may program RPM and one of the following: a) Time, b) Collapse Distance, c) Absolute Distance during the weld.|
|Hold/Cooling:||Pressure is maintained on the part after rotational welding motion has ceased. Allows thermoplastic material to solidify, ensuring the optimum bond of the two part halves.|
|Home:||Servo motor rotates back to its indexing or home position automatically.|
