Product catalog summary
Introduction to Vibration Welding: Vibration welding is a process used to join thermoplastic parts by heating their contact surfaces through oscillating friction. The process involves four phases: solid content friction, non-stationary melt layer formation, stationary melt layer formation, and cooling or holding phase.
Machine Technology: The vibration welding machines, such as the K 321x and K 322x series, use a vibration unit mounted on the machine frame to generate linear vibrations necessary for welding. The vibration is produced by solenoids and operates at resonant frequencies, with specific amplitude and frequency ranges depending on the series.
Applications: Vibration welding is versatile, suitable for mass production in industries like automotive, electrical, packaging, and white goods. It allows for the joining of different materials, including wood composites and textiles, ensuring high-quality welded joints.
Special Features: The bielomatik systems offer features such as variable frequency ranges, automatic frequency search, closed control circuits for amplitude control, and quick ramp-up and ramp-down of the vibration head. They also provide easy operation through a user-friendly interface and sound insulation for transport.
Technical Specifications: The document lists various models with specifications such as maximum tool weight, vibrating head dimensions, opening width, and welding force. For example, the K 3210 model supports a maximum tool weight of 20 kg and a welding force of 6.0 kN.
Customization and Additional Features: Custom-made systems include automation with robot loading/unloading, quick tool change systems, and infrared preheating options. Models like the K 3217-IR feature additional servo axes and hydraulic systems for enhanced performance.
Conclusion: Bielomatik offers over 55 years of expertise in plastic welding technology, providing technologically neutral advice and customized solutions for optimal production configurations.

Vibration Welding The procedure In vibration welding, the contact surfaces of the moulded parts made of thermoplastics are heated, plastied and material bond by an oscillating friction motion. Then the melted layer starts to cool. Welding phases In the joining path, a typical, time schedule – independent of component geometry, material and parameter selection – is applied, which can be further classied into four characteristic phases: Phase I: Solid content friction phase Parts to be welded are heated via interfacial friction up to the melting temperature. Structure of the vibration unit. Weld...
