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. In January 2000 KLN Ultraschall has joined the Crest Ultrasonics Corp., USA/Trenton, New Jersey, a group with international activities. All over the world a staff of more than 1.000 employees works on 20 locations in 12 countries. The complex technologies of plastics 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 200 employees works on complex customer projects. Plastic welding technology Standard machines for ultrasonic welding, ultrasonic multi-head machines, ultrasonic continuous welding for aluminum foil or thermoplastics, special machines, vibration welders, spin welders, hot plate welders, processing machines for plastics fuel tanks. Ultrasonic cleaning technology Ultrasonic vibration tanks, compact machines with drying feature, special machines, modular tank systems with agitation, rinsing, drying and rust inhibiting.

A Crest Group Company NFRARED WELD For welding by means of infrared technology short-wave (0,78-2 pm) as well as medium-wave (2-4 pm) infrared radiation of the spectrum can be used. This depends particularly on the absorption capacity of radiation of the respective plastic material. The more precisely the radiator is adapted to the absorption capacity of the plastic material, the higher is the degree of efficiency, that means the conversion into warmth. Short waves are absorbed in deeper layers of the material, whereas medium waves heat it up more at the surface. The nearer the radiation source...

Hot plate welding machine HE - SA Significant properties - High acceleration of the slide for the parts fixture and optionally also for the hot plate slide Precise speed regulation, depending on the travel Regulated braking of all travel motions Precise speed regulation, depending on the travel, in various steps of the melting and welding powers. The required parameters can be set at the TP. Exchangeable hot plates (standard size 350 x 200 mm) or exchangeable hot plate caps which are heated directly PLC control Siemens S7 with Siemens TP On request, all standard machines of the Toolmaster series...

A Crest Group Company NFRARED WELD Vibration welders with integrated infrared pre heating. KLN offers the possibility to integrate infrared technology in all machines or tools to minimise abrasion during the solid matter friction phase, by pre-heating with short or medium waves. • Vibration tool with infrared metal foil radiator in LVW2032. • Radiator unit with two each metal radiators (individual control) approx. 300 mm • Quick change over time < 3 sec. in order to avoid cooling of the welding joint. ground plate for IR radiator with #- integrated cooling system and mech. level adjustment panel...
