Possibilities of hybrid technology in decoration inside the mould

Marta Torres01/08/2003

The technical conferences organized by Demag, Wittmann, Creaprint and IML Robotics, at its headquarters in Spain in Sant Boi de Llobregat (Barcelona), offered more of an incentive. On the one hand, was an application of decoration inside the mould affordable and next, because it is an equipment one hundred Spanish hundred, which on the other hand, enabled to show the possibilities of adaptation of hybrid technology in the hands of the S. EL-Exis Ergotech

Demag Ergotech showed its clients in a few days of open doors (Barcelona, June 5-6) the possibilities for the production of fast cycle. For this he used a fast machine of hybrid technology, the S Exis Ergotech (which have been mentioned in detail in this magazine) and three axes of the brand Wittmann (model W633 UHSS) ultrafast Manipulator. The chosen implementation consisted of injecting a piece - a plastic lid - and their labelling within the mold. A series of technical talks were also organized during the Conference.

The application that was shown during the Conference has been developed by the company specializing in systems integration IML Robotics - Demag and Wittmann - owned in turn by the company Creaprint, manufacturer of labels, both based in Ibi (Alicante) whatAccording to sources at the company, "offers the user a guarantee of stability, both in the quality of supplies and prices". This system of decoration inside the mould is a finished product which does not require subsequent manipulations. Label is fused with the injected piece, the finish is waterproof and not rockets. The mould has been prepared by the firm ITC Indumat, also based in Ibi, which, according to the Demag firm, "goes to show that access to a high-tech is possible when choosing the appropriate partners and, most importantly"", at a reasonable cost".

In the central of Demag in Germany has been exploration to moldistas from around the world to find out if they can be adapted to a technology that use external cores

'Electrical' presentation

The managing director of Demag in Spain, Pedro Ordejón, wanted to place the emphasis on the advantages offered by the machine exposed in terms of speed and performance, although he stressed that it is a hybrid machine (with electric and hydraulic drives). In this regard, the director Manager of Demag announced that its representative in the Basque country, the firm Dewit, will present an all-electric model (machine IntElec, that already could be seen at the Plast in Milan) in Spain. The presentation will be done in a few days open in Bilbao are planned for the beginning of next year and where you can see a model of fuel transfer IntElec's series.

Ordejón also explained the priorities of the multinational Demag for years, passing through "enhance the electrical machine", on the one hand, and by specialization, on the other. In the opinion of the director Manager of Demag, the purely electric machine adapts well to all those technical applications for specific products that require a very fast cycle.

The hybrid machine, such as the exposed at the Conference, has its strengths in the speed, energy savings and the ability to inject very thin-walled.

Currently, the use of electric injection moulding machines follows trends opposite in European and Asian markets. According to information provided by Demag, in Europe they currently represent between 10 and 12 per cent, although the trend is increasing. In Asia, on the other hand, the percentage reaches 90 per cent, while it's electrical machinery "of low-priced and less accuracy".

External cores

In the view of Pedro Ordejón, all the machines used nowadays are hybrid, if only for the maneuver of expulsion. "This maneuver can be made by external teams, but you need a different mold with external cores," he added. This means that a machine can not be designed without thinking about the design of the mould and, therefore, in the moldistas. Ordejón said in this regard that in the central of Demag in Germany has been exploration to moldistas from around the world to find out if they can be adapted to a technology that use external cores. Also studies have been conducted with various universities.

Five sold machines

Demag in Spain plans go through close ties with official institutions and associations. Ordejón cited the Basque technological centre Lea Artibai, ASEAN Catalan moldista ASCAMM, AIMPLAS and AIJU in the Levant and the TIIP of Zaragoza.

Demag Spain has sold five hybrid machines this year, so, according to Peter Ordejón, probably it will exceed the six machines sold last year
