Through its Solid State Joining Center, Coldwater has developed its SPINMeldTM technology, which uses rotational friction to heat the materials along with pressure to create a solid state welded joint. In friction spin welding, one part is held stationary while the other piece is rotated on a spindle until the heat of friction between the parts softens the material to a plastic state, creating a solid state weld in fractions of a second.

Coldwater offers pre-production, prototype and low volume friction spin weld part production using its SPINMeld machines, which can join like or dissimilar materials including aluminum, magnesium, brass, steel and carbon fiber composites. SPINMeld machines are available to customers for integration into their work cell or as part of an automated processing line.

PART AND PROCESS DEVELOPMENT

Two high-volume Tier One automotive suppliers had issues with inconsistent quality

of incoming spin nuts (due to a torx bit drive feature) in addition to improper pickup/

drop out nuts. Scrap rates were running as high as 10%. Coldwater Machine conducted

internal testing and design review resulting in a new spin tool concept with an external

drive for the spin nut. Validation testing was completed and data reviewed by the Tier

One and the OEM. A 300 piece capability study resulted in 100% pick up of the spin nut

and 100% weld. This new pick up/drive design also enabled the OEM to reduce the nut

design features and height while increasing the thread engagement.

Result: Benefits of this approach include an anticipated throughput increase of 5% and

a material cost decrease of 10%.
