Welders from Branson Ultrasonics Corp., a subsidiary of Emerson Electric Co. (St. Louis, MO, U.S.), employ frictional heat at the joint interface of two mated parts. The heat is generated by moving one part against the other under pressure through a linear displacement or amplitude in the plane of the joint. When a molten state is reached at the joint interface, vibration is stopped. Clamping pressure is maintained briefly while the molten plastic solidifies to form a bond.

Branson’s M-Series linear vibration welder has transformed the appliance industry with its revolutionary welds. The M-Series includes high-power linear vibration welders, employing the company’s new two-phase digital drive. This drive technology enables higher power to be delivered to the parts to be welded. Washer parts, which include the front door and rotary drum, can now be assembled with relative ease. Whether used as a stand-alone unit or incorporated into an automated line, these welders deliver consistent results every time.

Key Features:

  • Ideal for welding similar and some dissimilar polymers.
  • Lower cost per weld compared with other methods for plastic joining.
  • Welding variables can be precisely monitored and controlled providing consistent results.
  • Energy efficient.
  • Easy to set up and operate.
