Helmut Roegele celebrates a technology day for customers in Barcelona

Nearly fifty customers have attended the technology day of Illig, held on 8 and 9 may at the premises of Helmut Roegele, S.A. in Rubí (Barcelona). His goal, and see first hand the third generation of Illig thermoforming machines, with the model 54 RDK performing a demonstration with a mold with built-in die of six figures with A-PET material, termoconformando trays at 50 cycles per minute. In addition, the practical demonstration was accompanied with a briefing on the latest technical developments from machines Illig: RDK, RDKP, RD53 and RV.

After a brief general presentation on the activity and history of Helmut Roegele S.A. conducted by Bernd Roegele, Managing Director of the company, were given briefings on Illig and the development of products RDK and RDKP by Marc Pohli of Illig responsible for signature at Spain; presentation and explanation of options of machines Illig: RDK, RDKP, RD53 and RV by Jordi Anguela, responsible for the area of thermoforming and the session on development of RD & RV products carried out by Jordi Anguela. The day concluded with the general technological presentation by Marc Pohli.

Machines Illig to manufacture castings of thermoplastics, both from a stock of plates and coils are used in most industry segments. For several decades, the company which last year celebrated its 60th anniversary, has become the basic technology of thermoforming a wide range of machines unique in the world. From the first generation of machines with pneumatic cylinders, passing by the second generation of machines with servo-motor, the third line of machines which completely changes the concept, the market has become more demanding and more sophisticated Illig offer:

Moulding plastic warmed with the device of previous drawing and compressed air, and in the same cycle stamping the molded part extract of the plastic sheet can manufacture parts molded without redshift of die cutting in the area of the edgewhich is especially important for the automatic processing of containers.

The great demands imposed on the mold / die and the knowledge gained during the thermoforming of high-performance machines RDM were transferred to the mechanical technology of RDK.

The machine has been designed to allow an easy to use, a flexible of the same design and a high reproducibility of all elements of operation involved in the process.

To meet the technology of molding and stamping, are indispensable conditions: a high stiffness of moulding and die cutting station and the maximum parallelism levels of tables of moulding.

To obtain optimum results of die cutting have been optimized the open-end levers, the tables and columns guides so that the forces of closure and die are highest. These forces are transferred to the tables through a double open-end levers and are generated by pine nuts moved by thread.

So not generated horizontal forces on the guides of the columns of the tables of moulding, the force is introduced centrally by the articulation of the double bent lever. The exact profile of the speed of the double bent lever allows that the maximum force is introduced during the process of stamping. Thanks to the possibilities of variable adjustment of the careers of tables and speeds along with tensor frameworks top and bottom, operated separately, fourteen different molding programs, with which it is possible without any problems all variations of molded parts are available.

Using the technology of servodrive used by Illig, with which can be synchronized together with great precision the movements of the moulding and the piston of preestirado table, can achieve an optimal distribution of the thickness of the side walls of the product.

The better distribution of the material involves, in addition, the very stability of the product for a lower thickness of the plastic's departure, giving rise to a qualitative product improvement, as for example a greater rigidity of the molded part and a few edges from sealed completely accurate and flat across the surface of sealing: these edges are reached by costumed cooled in the mould.

The machine has been designed to allow easy handling.

The modular construction of the machines offers great flexibility for various techniques of processes during the molding and stamping, and allows mold and stamping separately. Moreover technologies of processes can be completed through a die of grids of stamping, until you get a full installation.

An empty frame where to set these devices is used to place devices of suction, decorate the container or print barcodes.

The third generation of termoconformadoras allows, thanks to the innovative and functional structure of the programme, a strategy of optimization with which it is possible to improve on time performance, the quality of the products and the safety of production.

Setting data and process times, first determined with the help of the basic adjustment assisted by computer, can be optimized to the point that can be controlled overlaps of the sequences of the machine.

Without modifying the thermoforming process, such overlaps have a positive impact in the interval and work without detriment to the quality of the product.

A novelty is the newly developed user interface, enabling precise guidance of the operator through each of the phases of optimization.

This means that, for its optimization, the machine automatically prefija the relevant parameters for the output depending on the program of moulding, whose effects are represented in a newly-developed user interface for the operator.

An advantage of this display is the precise representation of the necessary information and functions, which helps the professional industrial design principles.

In Illig, synergies between the advantages for the customer and the development of thermoforming machines have arguably given rise to higher production capacities.

Advantages:

• It is not necessary to monitor and adjust the tension of the strings.

• Smarter transportation and a greater length of the chains that the tension of them always equals adjusted optimal value, which is the same on both channels.

• Less wear thanks to integrated cooling channels.
