spin welding

[′spin ‚weld·iŋ]
(engineering)
Fusion of two objects (for example, plastics) by forcing them together while one of the pair is spinning; frictional heat melts the interface, spinning is stopped, and the bodies are held together until they are frozen in place (welded).

Plastics joining technologies include ultrasonic welding, vibration welding, hot plate welding, spin welding, and thermal processing.
Popular joining methods used to assemble plastic components are: adhesive, solvent bonding, ultrasonic welding, laser welding, infrared (IR) welding, vibration welding, spin welding, radio frequency (RF) welding, and hotplate welding (HPW).
Spin welding is a friction method for joining two thermoplastic parts together, forming a molecular bond.
Spin welding can be performed either by inertia or direct-drive welding machines in a similar manner as for metals (75), (76).
Spin welding joins parts with circular joint surfaces using relatively simple equipment, sometimes just a drill press.
In the nonwovens area, the company offers precision cutting of baby diapers and sanitary napkins, although it is also experienced with a complete range of bonding techniques such as hot plate welding, vibration welding, hot air cold staking and spin welding.
To date, spin welding has not been successful in our bonding trials.
Sonics & Materials manufactures ultrasonic welding equipment, spin welding equipment, and vibration welding equipment, all of which are used in the bonding of plastics.
Also orbital vibration welding, a friction process that uses constant-velocity orbital motion to weld materials with as little as 30-mil part-to-part clearance; hot-plate welding, a direct thermal welding technique suitable for complex, irregular shapes (joint can be curved in all planes); spin welding suitable for circular parts with final orientation within 10, and thermal welding.
In the past, nearly all the frictional welding processes were linear (except for spin welding, which is only applicable for relatively small and round parts); however over a decade ago, orbital welding (5), (6) was introduced to the market.
Other types of friction welding include spin welding, angular vibration, and orbital welding.
has introduced new spin welding capabilities, according to the company.
