Infrared welding of plastics

Infrared welding of plastics is used in the most varied industrial processes.
Induction pipes, fan components and tanks for brake fluid or cleaning water in cars must be able to withstand pressure. Often, such plastic pipes and containers are injection-moulded in the form of half shells which are then welded together.
Infrared heat technology helps reliably connect the parts without causing particles inside the tubes.

Infrared welding of plastics

In many cases, a combination of infrared preheating and vibration welding is particularly advantageous. Infrared radiation melts the surface of the plastic, so that particle formation during vibration welding is minimised.
This ensures a reliable connection and high-quality containers.

Your advantages with infrared welding:

  • Contactless heat transmission, no material adheres to the heat source
  • Infrared emitters heat the surface of plastics within seconds
  • Infrared emitters can be precisely shaped to follow edges, rims and contours and heat these areas specifically
  • Infrared emitters heat selectively and reproducibly, which allows automation of the processes
  • Directed heat ensures optimal use of energy
