Customized Welding Projects

Building of special purpose customized machines is RTUL's speciality (Especially for the automobile sector). For many years, we have designed and built systems, which cater to the precise demands of the customer.

Customized Solutions For Complex Projects

For large/complex components, systems with multi convertor design (with mother/daughter horns)  are available as per specific requirements.

Multiconverter units: are frequently used in the welding of large-area, asymmetrical or very precise plastic parts, for example in automobile and apparatus engineering or with toys. The advantage of multiconverter system lies in the construction of small, simple sonotrodes which facilitates to optimize the weld quality along the whole weld contour due to local targeting.


  • Options available to locally influence, optimise and homogenize the welding quality along the entire welding joint line.
  • Increased operation reliability ( low risk for sonotrode and converter failure due to cracking ).
  • In case of problems simple trouble shooting procedure.

Multiple welding head with compound sonotrodes The robust construction of the USP3000 welding press and maximum clamping force of 3000 N allows the use of up to three 20 kHz oscillating systems with large, complex mother/daughter sonotrodes. The multiconverter welding head is shown as a single oscillating system as a snap-in unit and can be replaced as required by another welding head at any time without any great expense of time in a quick-change process.
