Engel: without columns, with ideas

Ibon Linazisoro15/09/2004

In a stand of 1,000 square meters Engel, represented in Spain by Helmut Roegele, particular emphasis will be on four themes: containers and packaging, technical multicomponent, precision parts, special technologies.

Engel MacPET - complete lines for the injection of preforms.

As with almost all the large companies, Engel also goes to the fair with a slogan: "Your applications - our solutions", this is the slogan under which Engel presents a wide selection of products and services. In a stand of 1,000 square metres, the presentation of Engel integrates the following areas of application: machines for containers and packaging, injectors for multi-component parts, precision injectors and special technologies. The presentation is complemented by a "Gallery of innovations" which offers the visitor a view of the latest developments of Engel in injectors and technological applications.

Packaging technology

For this field of application, Engel presents two new sets of injectors:

The MacPET series for PET preform: outlining a complete machine with 96 cavities mold, characterised by its good value for money. Engel MacPET is a new business division created following the acquisition of the business of injectors for SIG Corpoplast PET. The series comprises a complete system of production to PET fitted with moulds preform multicavidad (24, 32, 48, 56, 64, 72 and 96 cavities). The common advantages for all machines of this series are its system components tested, (for example, the closing of knee), its smooth action of plasticizing (thanks to the barrier spindles of Engel), its attractions and economic packages, strong partnerships with manufacturers of molds, systems of control of temperature and equipment for the treatment of the material, and a worldwide after-sales service.

Watermelt improves the properties of this boxes.

The new system Engel MacPAC, he made his debut at K'2004, machine cycles faster to manufacture containers: is an Engel MacPAC 330/125. These fast cycle machines are equipped with closing of knee of five points and are mainly designed for the mass production of packaging for products such as ice cream, yogurt and margarine tubes. The MacPAC series integrates machines with a range of closing forces which will go from 1,250 up to 3,500 kN. The capabilities of these machines for packaging will demonstrate during the contest with a machine of 1,250 kN working with a cast of two cavities of Greiner Verpackungen. It is completed with automation devices for stacking containers. The cycle time to inject a PP container is just 2.9 seconds.

In the packaging sector the exhibition is completed with a cell of production based on an Engel Duo 7050 / 1100 two dishes to manufacture a box of high volume folding for fruits and vegetables, developed in close cooperation with the Austrian moldista Haidlmair. In this case, the greater rigidity of the piece, with a clear decline of its deformation, is achieved through the use of the technique of injection assisted with water Watermelt. Their advantages over the injection gas in injection of hollow parts are related to cycle (40 to 70 per cent shorter), the regularity of the thickness of walls and the attainment of inner walls more smooth.

Pieces multicomponent injection

The second focus of the presentation by Engel during the fair is the technology multi-component - which is shown by Engel Duo Combi CS machine equipped for the production of a moon of car roof. The name "duo Combi CS" is given by a specific variant of the well-known machine Engel Duo of two dishes, in which two injection units are arranged horizontally and one against another: the main injection in the normal position and the second unitlocated in the place of the ejector in the mobile Bowl. Added to this configuration of the machine is a module of rotating table in the unit's closure that can be used for two or four seasons operations and supports the central cube of the mould of double opening. Along with its Italian partner Incos, Engel will demonstrate the production of the Moon from the roof of a car.

The second application that will serve as example in the field of technology of multi-component injection will be on the machine without columns Engel Victory 200 H/w/80 Combi, with the second unit of injection mounted in oblique position on the main unit. The novelty this machine presents is the turntable's three stations with axis of eccentric rotation, a configuration which is only possible with unit locking without columns.

Electrical precision of Engel

For the application of precise parts area, Engel presents two production engines servoeléctrico cells. One of the examples shows the production of a case of battery for mobile phones, with only 0.15 mm wall thickness and a cycle of approximately 5 seconds (including the time of anti-corrosion). Resorting to a 200/55 E-Motion Engel equipped with a cast of four cavities. The machine, which also shows the virtues of new technology of Engel X-Melt, is equipped with a high-speed series Engel ERS-1 robot.

The core of the second example of production of precision parts for cell is the Engel Victory 200/60 Electric machine. This innovative machine unifies the advantages of the Engel Victory (hydraulic and without columns of system) and electromécanica of the E-Motion series injection unit. The machine is presented with new technology Engel Optimelt for molding by inyección-compresión of high quality optical components.
