Vibration Welding

»Information

T.A. Systems high frequency vibration welders are the ideal assembly solution for large, contoured, or complex thermoplastic parts which require welding with short cycle times. All T.A. Systems' machines are designed for versatility and easy tooling changeover to accommodated a variety of parts. Typical applications include automotive door panels, glove box assemblies, knee bolsters or any thermoplastic materials of compatible melting temperatures. Thermoplastic bonds are easily achieved and finished part weld strength approaches that of the parent materials.

Vibration uses a linear motion to create heat, which is subsequently used in combination with pressure and time to bond thermoplastic assemblies.

The lower part is held stationary in a fixed tool while the upper (mating) part is vibrated in a linear motion at over 200 Hz. The heat generated from this friction in combination with the hydraulic pressure of the machines bed (lower nest) creates heat in the weld joint and a bond between the two part halves.

»Sequence of Operations

  1. An operator loads the components to be welded into the lower nest(s)
  2. The cycle is activated
  3. The part is welded as described
  4. The pneumatic door opens automatically at the end of the machine cycle
  5. The finished part remains in the lower tooling for removal
