Founded in 1947 by the physicist Dr. Lehfeld and known since 1972 as KLN Ultraschall, we are today one of the leading European manufacturers of machines and equipment for welding thermoplastic parts and ultrasonic cleaning technology in Europe. Jersey, a group with international activities. All over the world a staff of more than 1.000 Multi-head Systems employees works on 20 locations in 12 countries. The complex technologies of plastics In January 2000 KLN Ultraschall has joined the Crest Ultrasonics Corp., USA/Trenton, New welding and ultrasonic cleaning are the main activities of the Crest Group. Currently at the German locations in Heppenheim and Fürth an expert team of 180 employees works on complex customer projects.

Ultrasonic multi-head machines for plastic parts Ultrasonic riveting: In plastic parts which are not suitable for ultrasonic standard machines due to their size and re-shaping of pins, hollow pins or bridges for the fixation of components, e. g. reinforcement inserts. characteristics, it is recommendable to find individual solutions with several ultrasonic units for the ultrasonic welding and processing methods. Welding Riveting Spot welding Punching Beading These machines can also be designed for complex problem solutions. They can also be combined, for example, with other welding...

The modular changing system punching machines with precise radius design on the surface, e. g. for punching holes Makes possible the tooling exchange for different parts, keeping the basic machine. The for incorporation of distance sensors in lacquered bumpers or lamp cleaning units. KLN program comprises all types of ultrasonic multihead machines. flexible piping system actuators control display for ultrasonic units frame construction upper tooling welding nest (lower tooling) Tooling Ultrasonic punching: production of round or angular holes with high precision, whereby the component is...

A Crest Group Company MULTI-HEAD SYSTEMS Ultrasonic technology in Multi-head machines • Ultrasonic welding: considering mostly the roof-shaped welding additives (energy directors). Welding by means of friction at the connecting surfaces. • Ultrasonic riveting: re-shaping of pins, hollow pins or bridges for the fixation of components, e. g. reinforcement inserts. • Ultrasonic punching: production of round or angular holes with high precision, whereby the component is preserved; also suitable for already lacquered surfaces. • Spot welding: Patented technology for high-tensile and compact...

Flexible KLN piping system for free adjustment of the operating positions. The pneumatic feed units are fixed preferably in a flexible piping system. This allows the unrestricted adjustment of the welding positions in all directions. Like this parts modifications during the manufacturing phase can be taken into account without causing additional costs. Multi-head especially For other applications in US Multi-head technology like instrument panels, center consoles, door panels etc. please ask for brochures and complete program. View into the interior of a special ultrasonic machine for the...

Wide range of application Ultrasonic generators for plastic parts in the automotive industry, for example column panelling with wrapping State-of-the-art plug-in technology as well as modular versions for the frequency ranges technique, I-panels, door panelling, centre consoles, spoilers, bumpers, coating with 20, 30 and 40 kHz, capacity from 700 to 3000 Watt. All generators are equipped with a sound protection, cluster (instrument carriers) etc. Apart from this these machines are communication board for operation at a PLC. used also in other industry branches, like in the appliances...
