Harden Steel Spin Welding Tool

Spin Welding is the preferred technique for thermoplastic parts with a circular axis joint which have high bond strength/hermetic requirements. During Spin Welding, one part is held stationary in a holding fixture while a second part is rotated against it under pressure at speeds up to 16,000 rpm. This resulting friction causes the joining surfaces to melt and fuse together, producing strong hermetic welds. Spin Welding Toolings consist of Driver Holding Fixture Holding Fixture: The non-rotating part half must be held securely so that one part half does not rotate and remains in alignment with the spinning part half. Part details such as protrusions and lugs/ribs on the outside of the part aid greatly in preventing rotation. Our Standard Spin Welding Toolings are made from Steel, Aluminium or Titanium.
