ENGEL glazemelt

Car windows in all variations.

For large parts, and especially for long ENGEL duo combimelt parts, Engel offers an ENGEL duo (largecapacity, two-platen) machine configuration with a rotating module mounted on a carriage within the clamping unit and two injection units working in conjunction with the two platens.

The horizontal plane of rotation and the cube-shaped central block of the injection mould permit better utilization of the available space between the tiebars than is possible with a rotary table system. A particular advantage lies in the diametrically opposed arrangement of the injection units on the two platens.

This permits a relatively simple design of the central block, as there is no need to equip it with a bypass hot runner. The system is particularly suitable for the injection moulding of large-area parts with integrally moulded seals.

The process

The rotary module, which rotates in a horizontal plane, supports the central block of a double-daylight mould. Rotation of the cube-shaped central block permits optimum utilization of the platen area between the tiebars. Rotating in steps of 90°, the central block affords ready access to insert-placing or parts-removal robots. Like the central platen of a conventional double-daylight mould, the carriage-mounted central block is kept in a central position during the opening and closing of the mould by means of an automatic hydraulic control
