ILLIG present their latest line systems for thermoforming of sheet material. These lines are suitable for manufacturing products for various applications in electrical engineering, electronics, automobile and vehicle construction, general industrial applications through to household, leisure and sports articles. The all process-controlled universal forming machines of the UA-g series provide a comprehensive, product-oriented variety of types and different equipment levels featuring different forming areas. In all of these sheet processing machines high precision and repeat accuracy is combined with high productivity, product quality and efficiency. The innovative air ducts for ventilating and air condition systems in automobiles document, among other things, the efficiency and versatility of this generation of thermoformers. They meet demands in today's automotive engineering to a very high extent.
Performance feature of process-controlled ILLIG UA-g sheet processing machines is the consistent use of servo drives. The user benefits from a lot of advantages. Movements of individual functions can be performed faster with individual speed profiles adjusted to the respective process level. In total this results in shorter cycles and thus considerably increased cycle speeds. The precise and in particular fast movements at the same time have a positive effect on product quality, since e.g. pre-stretchers are moved dynamically and with defined speed and almost independent of surrounding conditions. Areas of pronounced forming can be stretched in a selective way and formed exactly with repeat accuracy. In this way thinner basic materials can be used (sheet or roll material) which adds to higher efficiency. Moreover, energy consumption of servo drives is lower compared to that of pneumatic and hydraulic drives. The UAR 155g sheet processing machine, adapted for thermoforming of air ducts in the so-called twinsheet method, also makes use of these technological possibilities. Roll material can be processed on a forming area of 1.250 x 1.500 mm² on this machine.
In the UAR 155g the drives of upper and lower table as well as the loading device, among other things, were adapted for forming and punching of twinsheet parts in the forming station. The loading device is equipped with a servo-driven double material transport with toothed chains for two material webs, servo-driven width adjustment of transport as well as servo-driven height adjustment for upper and lower material transport. The foamed materials are drawn off by two rollers and processed. Thanks to the large forming area of the UAR 155g thermoforming machine long as well as large-area parts can be manufactured. The forming area can be used in almost any layout for small parts. This new technology is also suitable for many more applications from all different materials besides the production of air ducts.
