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).

These include hotplate welding, spin welding and ultrasonic welding.
Technology for spin welding a resin tube to a joint part from one direction has been practically applied.
Spin welding is a friction method for joining two thermoplastic parts together, forming a molecular bond.
Spin Welding. In this technique, also known as "rotary friction welding," welding pieces are placed into contact and rotated, aiming to accomplish heating by friction (74).
Since its inception MPI has grown in staff and capabilities to include the manufacturing of catheters and medical devices and offer the additional services of catheter tipping, skiving, hole punching, pad printing, RF tipping, ultrasonic welding, solvent bonding spin welding and many other services for device manufacturing.
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.
Plastics joining technologies include ultrasonic welding, vibration welding, hot plate welding, spin welding, and thermal processing.
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.
The LTR3000, 4000, and 5000 Series Spin Welding machines are small footprint system that are designed for bench top production.
