CONSIDERATIONS:
1. Parts joint must be on a circular axis. Full rotation of part not required. This frees design typically limited by conventional spin welding.
2. Joint design should allow for sufficient collapse distance, insufficient collapse may cause external welding and possible flash resulting poor weld cosmetic quality when applicable.
3. Determine whether or not final orientation of parts is required.
4. Flash produced during the process should be taken into consideration. However, our process produces a minimal amount inherent to spinning only 1 or 2 revolutions.
5. Parting line must be parallel to the force applied by the driver. Typically, upper part half will be designed for use with drive features (areas for driver to engage part). Optional tooling availble that drives part without drive features.
6. Material selection may have an impact on joint design and welder type (orientation or inertial). Part must be designed so that there is no contact (other than the joint area) between the spinning part half and the fixtured part half.
