High-efficiency cooling structures for electronic components.

  • PA6 housing with integrated aluminum cold plate instead of solid aluminum
  • Improved thermal management thanks to the insulating effect of the polymer on the outside
  • Weight reduction of up to 50% possible
  • Joining costs reduced by up to 75%

  • Up to 80% lower CO2 footprint

  • Short cycle time – no pretreatment, no sealants, no curing times

Protection for batteries, sensors, and smart devices.

  • Gas- and waterproof welded (up to IP68)
  • No curing – immediately load-bearing
  • Distortion-free sealing of water-carrying cooling channels
  • Validation of flow simulations using transparent polymers
  • Ideal for inverters, battery trays, and other long-life systems

Polymer–metal hybrids for durable home appliances.

  • Polymer front welded directly to metal hinges
  • Display protection
  • Surface-based rather than point-based force transmission
  • 30% fewer individual parts, shorter assembly time
  • No contact corrosion, no settling of screws or seals
  • Applications include washing machines, refrigerators, and ovens

Curious about your own component?

Our feasibility study shows within six weeks how Polymer Stir Welding can make your electronic housings more sealed, more sustainable, and easier to assemble – including a functional prototype.
