Branson's orbital vibration welders are complete assembly systems
designed to weld large or irregularly-shaped thermoplastic parts. The
equipment can operate at low weld amplitudes (less than 0.030" in some
applications), which reduces part clearance requirements and enables
welding of unsupported vertical walls.
The orbital welding process provides designers greater latitude in
designing plastic parts. Spin welding is restricted to circular joints
and linear vibration welding has difficulty with unsupported joint
walls perpendicular to the axis of vibration. These constraints do not
apply to orbital welding, since motion is in all directions. In
addition, the ability to program motion allows weld paths from a circle
to a straight line to be selected. An elliptical path can be set at any
angle. In other words, the motion can be tailored to the part shape or
weld requirements.
Standard features include: closed loop amplitude control, adjustable
frequency, opti-touch sensors, and process verification software for
evaluating weld quality.
