Vibration Welders
GENERAL DESCRIPTION: Branson, the pioneer in vibration
welding with over 40 years of production experience
is proud to offer the enhanced version of our popular HyLine
2 Series linear vibration welder. Featuring the
all-new I-Class weld heads, Branson’s HyLine-2i Series
welders are complete assembly systems designed to weld
parts of various sizes and/or irregular shapes.
The I-Class weld heads offer multiple benefits including: increased tool weight capacities, increased
tool weight to frequency ratios, higher power drives (more plastic joining capacity), PPL technology
(see Machine Description section), interchangeable/common parts across weld head models, global
commonality, and lower noise output.
Three models, VW-4i1 H, VW-6i2 H, and VW-6i3 H are available to handle parts up to 46” by 22”
(1148 by 559 mm), or multiple smaller parts.
The Branson power supplies that drive the weld heads have an adjustable vibrating frequency range of
180 to 240 Hz. Modular construction allows the individual vibrator assembly and power supply/controller
components to be adapted to automated or custom systems.
Process Description
Vibration welding is a proven welding technology capable of producing
strong, pressure tight joints in thermoplastic parts.
Frictional heat is generated by pressing the surfaces of two plastic parts
together and vibrating one of the parts through a small linear
displacement in the plane of the joint. When a molten state is reached at
the joint interface, vibration is stopped and the parts are automatically
aligned. Clamping pressure is maintained briefly while the molten plastic
solidifies to form a bond approaching or equal to the strength of the
parent material.
