The best equipped, highest value spin welding machine in its class.


Servo-driven spin welding

The Vortex® PRECEDENCE™ servo-driven spin welder is the best equipped, highest value machine in its class.

The Spin Welding Process

Spin welding is a method of joining plastic components together with surface friction concentrated in a circular weld joint. One part is spun relative to another and force is applied, causing the material to heat and melt. The spinning process stops and the parts continue to be pressed together while they bond together.

Vortex PRECEDENCE Overview

The Vortex® PRECEDENCE™ servo-driven spin welder is the best equipped, highest value machine in its class. The rugged cast iron column and heavy-duty aluminum base set the foundation for achieving robust and repeatable weld assemblies. An integrated power supply/controller keeps the footprint of this benchtop unit very compact.

Vortex PRECEDENCE Benefits

Process Control

Proprietary electro-pneumatic z-axis control system allows for programmable, in-cycle force and velocity changes while providing dynamic follow-through to the weld.


10 HP peak power servo-drive motor provides up to 1,210 in-lb of torque (G5 model).

Space Efficient

Fully-integrated power supply, controls, E-stop button, and operator interface means there is no bulky control box taking up extra space.

Easy to Operate

Comprehensive and intuitive graphical interface makes for easy setup and even easier operation.
