Ultrasonic laboratory plastics

Here, we perform concrete evaluation of weld tasks. In the laboratory report, which is handed out to the customer, the results are explained in detail.

  • Joint design, including a CAD image of the energy director (ERG)
  • Microscope image of the welded section, dimensions of the ERG
  • Verification and validation of requirements, e.g. in terms of strength and tightness
  • Recommendations for machine configuration and integration
  • Graph of the weld process, including all weld process parameters

 

 

 

  • Application consulting / joint design

    • Consulting for component design
    • Support and direction for designing the weld geometry (weld joint)
    • Principle testing for feasibility
    • Consulting for material selection



    Weld process development

    • Preparation of the weld concept
    • Development and manufacturing of application-specific weld tools
    • Definition of the weld process parameters and specification of the process window



    Application optimization

    • Trials and tests in partnership with the customer
    • Optimization of weld tools 
    • Validation of the test results by tensile tests, sealing tests, burst pressure tests, high-speed camera, microscopy, thin sections, thermography
    • Performance, documentation and evaluation of test series (DOE = design of experiments)

     

     

     

  • Test rigs

    • Design and configuration of application-specific test rigs
    • Near-production tool layout
    • Application-specific measuring instruments

      


    Prototype production 

    for:

    • Quality control and component validation
    • Prototype supply of the final customer
    • Function tests, e.g. environmental change tests

     


    Contract manufacturing 

    • Very small series production
