CEMAS elettra - Your partner in plastic joining Open/Close PRODUCTS> LASER LASER TECHNOLOGY, THE FUTURE IS NOW THE HIGHEST UNMATCHED MODULARITY ON THE MARKET In order to satisfy even the most stringent and complex requirements, CEMAS laser system has been designed with a fully modular architecture. Currently our machines are the only one on the market provided with a single modularity system ("one by one" sources architecture), so as to allow the highest level of customization. This means that, according to the customer production needs, it is possible to equip the machine with a certain number of sources and, later, integrate more of them, one by one, up to reach the required quantity. Indeed, thanks to a careful feasibility study, we are able to precisely estimate the number of sources necessary to complete the welding process of a specific product. Working in this way, we can always guarantee the best quality-price ratio, allowing our customers to purchase only the components they really need. ACCURATE TOOL FOR PERFECT WELDING We take care of our tooling No detail is overlooked: our machines are designed to optimally manage all the welding process variables, in order to ensure high standards of efficiency and reliability, with a low energy consumption. To realize machines capable to respond to any production expectations, the tool manufacturing is preceded by a careful virtual modelling and prototyping process. The beam tracing process, using CAD finite element analysis software, allows our engineers to simulate how the light acts in the waveguide. This process is fundamental to design efficient tools without wasting time. AIR COOLED SINGLE STAND ALONE UNIT This small laser welding machine is equipped with one laser source and one laser fiber. Its size is similar to a "shoe box", has been designed to be easily integrated in other machines of the same production line, where individual and small joints are necessary, even distant one from each other (e.g. for the bumper parking sensors).

AIR COOLED LASER BANK Equipped with three laser sources, it is ideal for small welding machines where it is not possible, or it is not convenient, to have a liquid chiller system. Each laser bank, it provides up to 150 W on the component to be welded.

The smaller simultaneous multi-fiber laser welding machine of its range, suitable to realize both laboratory welding tests or mass production of small part, it is extremely compact. Thanks to its Tec air cooling chilling system, which allows a precise control of the temperature (in the order of 0.2° C), it is able to reach high levels of efficiency. The machine can be implemented with up to four laser banks (MF 30) and, for this reason, it is available with different power size: 150, 300, 450 and 600 W. The press movement is servo controlled so as to assure an absolute precision and dynamic. Despite the dimensions, it is able to exert a clamp maximum force up to 400 kg.

WATER COOLED The largest of their range, these machines are developed to weld medium-big size components and they are particularly suitable for rear lamps. The 480 and the 960 are structured on two levels of modularity: LEVEL 1: in the head of the machines it is possible to install up to 3 rack (for the 480) and up to 6 rack (for the 960); LEVEL 2: each rack can be equipped up to 16 laser sources, 8 per side; the modularity is of one source by one (up to 48 sources for the 480 and up to 96 ones for 960).

WHY BUY A CEMAS LASER MACHINE clear and irrefutable strong points Adaptable Simultaneous multi-fiber laser welding guarantees a superior welding depth than the other laser applications. Indeed, is able to optimally weld, both on the aesthetic side and on the strength one, also components "not totally perfect", with some shape imperfections. Extremely clean This is a non-contact welding technology. For this reason does not produce smokes, dusts, and particulate and it is totally wear-free. Indeed, in laser welding, the components to be welded are placed in "soft contact" and are not stressed during the production cycle (as it happens, for example, for the vibration welding). Efficient The simultaneous multi-fiber system allows to heat instantly and concurrently the entire weld path, resulting in an extremely constant welding depth. In addiction, the zone to be melted is small and local, so there is no energy dispersion. Fast Thanks to the simultaneous welding process, it is possible both to significantly reduce the machine cycle time and to ensure exceptional quality, cleanliness and flexibility (geometrical joint limitations are yet to be discovered!) of the welding process. Modular and flexible This technology fits, like no other, to all production requirements, since it is possible to increase or decrease the number of laser sources according to the needs. Highly reproducible process The precision clamping with no relative motion of parts during the welding cycle assures a highly repeatable welding process and consistent joint quality. Aesthetic in first place This technology is dedicated in particular to the welding of rear lamps (in single or double cavity) and of all those components for which aesthetic side of the joining is simply essential. The flash is minimal. Highly customizable No compromise for quality Easy maintenance Ergonomic loading station Reliability Energy saving technology Innovative and user friendly UI Cutting edge technology and fully equipped machines as standard. Discover more THE LASER WELDING TECHNOLOGY The term "laser" is an acronym for Light Amplification by Stimulated Emission of Radiation, and describes a physical process: an amplified concentration of light energy at a specific wavelength, capable of focusing on a specific point or on a narrow beam spread over a long distance. HOW DOES IT WORK Using the "diode laser system" (usually at 980 nm, but other wavelengths are possible) the welding process with laser irradiation allows to join a plastic absorbent component with a transparent one (so called as it is transparent to the infrared wavelength used). The infrared radiation, driven by waveguides, passes through the transparent part and heats the absorbent component. Reached the melting point, the absorbent component, according to the principle of conduction, heats the transparent one, allowing the real welding. Finally, to ensure a perfect welding and sealing quality, the two components are pressed together by a mechanical press.
