Illig: Pavilion 3, stand A52

Illig will be exhibiting at stand third-generation machines: RDK and RDM models and their molds. The RDK series for the trainee and cutting is used to produce products from trays with hinge and others for menus, even for tapas. The RDM-K-series machines are used primarily for the thermoforming of vessels and containers of different designs and sizes in multiple-cavity molds. Compared to the previous standard systems, are achieved increases which doubled the speed of the cycles, demonstrating a better quality of the product to a low energy consumption at the same time. The same applies to machines termoconformadoras of plates of the aserie au, which will also be showcased, along with the others in this fair K.

In the production line of the RDK 90, the largest version of these automatic termoconformadoras by compressed air, materials can be processed to a width of 900 mm with an advance of 700 mm, for the production of trays and packaging of fresh produce. The material to be processed will be APET with a cast of 18 cavities at a speed of 55 cycles per minute. In the automatic termoconformadora RDM 70 K with an area of formed 680 x 300 mm, produced containers of yogurt in a mold of 27 cavities using sheet APET. End of line equipment ensures a reliable handling of this large volume of 50,000 trays and almost 70,000 containers for yogurt production. For this purpose, the RDK 90 line is equipped with a dual system of manipulation for the remote device and stacking.

The servo motors used for all sequences of movements are one of the prerequisites to achieve high speeds of cycles in the termoconformadoras. They work an economically as well as fast and precise way thanks to the precision of positioning and repeat, being able to use other steps in machine downtime, which means a considerable saving of time of process. High dynamics involved in the formation and reduction of air pressure of forming is also a crucial element in the clear improvement in productivity compared to the previous generation. These are decisive factors in the RDM-K series of 3rd generation. They operate with up to 75% less volume of air by cavity resulting in an increase in the speed of the cycles of up to 30% and achieving, at times, values significantly more high. The thermoforming with multiple cavity tooling, allow, considering the quality of the product, the uniformity of all geometries of vases and pots. Based on this, achieved a reduction of weights with the subsequent saving of material up to 10% without giving up the dimensional accuracy and stability of the vessel or pot.

Developed the first time for the great termoconformadora RDK 90 (as well as the RDM 70 K which will be on display during the fair for the production of vessels, K) that can be equipped with the new concept 'illig thermolinecontrol'. All additional devices and lines required to complete the production line, from the portabobina, additional devices for cooling, can be handled and operated centrally via the control of the termoconformadora. In addition to providing an increase in the convenience of the operator, for example with the optimization of the process, data management and visualization of the process, yet the necessary unproductive side times for tooling change are reduced considerably.

Servo motors used for all movements of the termoconformadoras not only contribute to an increase in production, they have a positive effect equal on the energy balance. Provided units are equipped with an energy recovery system. The generative power of the available system, for example, energy of braking of one or more engines, is used for other engines or loads, as well as others also for infrared heating system. Depending on the type of each machine and its engine, this saving is 20% approximately, the power of the engine.

The topic of energy efficiency, is much more complex for the thermoforming, since engines require a maximum of about 10 to 15% (according to each machine) of the total energy of the thermoforming process requirement. In addition to others, the following are influential elements: type and use of infrared heating for the heating of the material, requirements for the control and the temperature and cooling devices and energy - for machines that are fed with coilsAutomatic, working predominantly with compressed air, an important energy factor - requirement of energy for generation of air from forming.

At the K fair, Illig will demonstrate how to combine the high productivity of the thermoforming at the same time with an energy consumption that saves sensitive operating costs. Comparative measurements on machines Illig of previous generations, have shown that these 3rd generation provide energy savings in the order of 50%, which confirms that they are significantly more efficient and profitable.
