Eurosonics — Your solution for plastic welding
FREN
Technologies

Four assembly processes, mastered in-house.

We don't champion any single technology — we champion the right one for your part. Here's what we do.
Ultrasonic weldingView products
01 / 04

Ultrasonic welding

Ultrasonic welding uses high-frequency vibrations (20, 30, 35 kHz) to generate localised heat at the interface between two plastic parts.

  • Short cycles (< 1 s)
  • Clean assemblies, no filler material
  • Ideal for amorphous and semi-crystalline thermoplastics
  • Insertion, staking, continuous welding

Vibration welding
02 / 04

Vibration welding

Linear vibration produces controlled friction between two parts under pressure. Suited to large surfaces and technical parts.

  • Surfaces up to several hundred cm²
  • Compatible with filled materials (fibres)
  • Ideal for automotive: tanks, manifolds
  • Fluid- and gas-tight sealing
Hot plate welding
03 / 04

Hot plate welding

A heating element plasticises the surfaces to be joined, which are then pressed together. Robust and versatile.

  • Challenging materials (filled PP, PE, PA)
  • Perfect sealing
  • Large parts, complex geometries
  • Non-contact option available (IR)
Thermal & staking
04 / 04

Thermal & staking

Heat staking, insertion, hot marking: thermal processes round out our offering for your hybrid plastic-metal assemblies.

  • Heat staking
  • Metal insert embedding
  • Hot marking
  • Can be combined with ultrasonic
