Ultrasound welding - for plastics - Import export

We offer high-quality ultrasonic welding, using market-leading production machines.

For the assembly of plastic parts, which differ in size and condition and would therefore not be suitable for standard machines, we recommend the use of special equipment with several ultrasonic units for ultrasonic welding and processing methods. • Riveting • Welding • spot welding • punching • flanging • cutting • embossing • printing Multi-head systems These machines can also be used to accomplish complex tasks, e.g. the combination of different welding techniques, like spin welding and hotplate welding and for numerous automated processes

In the last few years KLN has enlarged their hot plate welding machine program „TOOLMASTER“ and their vibration welding machine program “LVW” by the infrared welding program. The KLN machine program of „pure“ IR welding is based on the hot plate machine program „TOOLMASTER”. Machines for infrared heating should be equipped with servomotor drives in order to guarantee simple, quick and exact positioning. For welding by means of infrared technology short-wave (0,78-2 μm) as well as medium-wave (2-4 μm) infrared radiation of the spectrum can be used. This depends particularly on the radiation absorption capacity of the respective polymer material. The more precisely the radiator is adapted to the absorption capacity of the polymer 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 Ultrasound washing machine cleans and degreases plastic materials or acetate in general or small pieces in metal in water and/or cleanser. The cleaning action in a ultrasound washing machine is due to the vibration and cavitations produced by high frequency sound waves. They are not the ultrasound that clean the object surfaces but the fine cavitations and important molecular vibration. According to the Company’s Philosophy, only high quality materials are used. Production is respectful of security norms and the machine is completely made in stainless steel. For a better control of the process, the machine is equipped with: – Ultrasound transducers situated on the bottom or on the inside – Liquid Heating controlled by a thermostat – Power regulation – soundproofing and insulation – tank for rinsing by immersion with spray controlled by pedal – top to close tanks

The new generation of plastic welding machines of the OMEGA 4 series combines technical standards at the highest level with ease of use. The modular arrangement of the machine components, consisting of press, control and generator, enables easy adaptation to the respective plastic part and the respective location. Simple system operation is guaranteed with the multilingual touchscreen With this standard machine, even the most difficult welding tasks can be mastered reliably thanks to their performance and control and monitoring options. The A series is the basic version of the Omega. Time and energy measurement are available for process monitoring. Compared to the S-du X-series, the generator and control are combined. This makes the A-series more compact, but limits the number of welding modes and storable programs.

The S series is the standard version of the Omega. An ultrasonic high-performance generator and and a separate control with a larger touch panel are available. There are also 12 program memories available. The separate control also enables the process data to be read, the travel distance to be measured and greater connectivity.

Basically the TOOLMASTER versions vary by their tool design, their size of useable surface and the degree of automation. All versions are suitable for high temperatures and optionally equipped with fire protection engineering, which quickly separates the tool in case of energy drop or timeout. KLN also manufactures special machines adapted to your individual requirements. TOOLMASTER "Basic" as well as type HE 50/30 are standard machines. The versions "Advance", "Semi-Automatic" and "Automatic" are made with tools in sandwich design. This makes possible the handling of upper tool, hot plate element and lower tool as a compact unit. They are designed particularly for quick and frequent production changes. The HE/SA has a horizontal concept with servo-drive technology for quick and precise movements. The TOOLMASTER CC has been developed for applications with two welding tasks in one cycle. Almost all machine versions can be provided with pneumatic or servo-motor drives.

The X series is the premium version of the Omega series. This series is also equipped with a proportional valve for a defined pressure control. In addition, this Omega series has a pneumatic pressure / counter pressure system and thus ensures smooth movement even at low pressure.

The REK-B offers all advantages of the high technical level of the OMEGA III series, particularly regarding precision and reliability. The machine may be integrated in an automatic production line and controlled via a higher-ranking control system (PLC). Options: • Hydraulic oil brake • Working table • Housing • Light curtain • Rotary table • Control of external periphery Advantages: • Easy programming via touch panel TP 270 • Display of time-travel curve and pressure-time curve after the welding cycle on a graphic display with plain text. • Regulation of the welding forces via proportional valve technology. • The machine REK-B offers many possibilities for analysis, control and regulation. • Three welding models in order to meet the requirements of each application • Positioning of the spin head prior to and after the welding process • Display of the ongoing process parameters ( welding travel, -time).

The device is used as hand pistol for riveting, welding and edge folding of plastic parts. The weight of the welding pistol is lower than 900 g. The optimum design of the welding pistol allow for a particularly comfortable handling. The titanium booster ensures a maximum safety of the converter and optimal adaptation to the various tools. Advantages of the SPK version: By the permanent cooling of the piezo-ceramic transducer and the titanium booster an extremely high performance period can be achieved. The cooling air pipe is integrated in the HF control cable. Advantage: No disturbing connective elements for a separate pipe, and the cooling air is led directly to the spots to be cooled.. For this the grip is fitted with an exhaust port for the cooling air, into which cooling pipes can be simply screwed in. In this version the generator is also cooled by an incorporated ventilator. As an option we can offer hand welding devices with energy control

KURO cable protection pipes made of unplasticised PVC-U are ideal for the pressure-free underground installation of power and telecommunications cables. They also ensure perfect protection against all kinds of mechanical damage when used as cable protection pipes. HERE‘S HOW YOU BENEFIT: - Manufacture according to DIN 16873 and 8061/8062 - Advanced integral ring seal socket technology with permanent seal and long socket

The LVW series covers smaller applications with machines of approx. 500 mm width and large applications up to a width of 2000 mm, like pallets, bumpers and more. As a principle our standard machines are equipped with an hydraulic lifting table. Depending on the machine size a contact force of up to 70 kN can be applied. This is necessary for large suction pipes made of PA 6.6 GV30 with heavy distortion or very large welding surfaces. Our vibration welders are fitted with our patented CPC system. This kind of regulation which is integrated in the converter stimulates the vibration unit with optimal resonance frequency. A low energy consumption is guaranteed during the friction phase. It is not necessary to enter the frequency parameter in the machine, as it is permanently “optimized”. This, the KLN drive systems are independent from the tool weight. The tool weight is solely limited in height, caused by the mechanical design and the high accelerating powers arising in these systems.
