Components

Driving unit and extruder are optimised and all components designed for continuous operation, so that this extruder is suited for use both in the laboratory and on-line parallel to production.

The extruder and the driving unit are mounted on a housing in which the electric drive components are situated. This housing in turn is situated on a steel frame, which stands alternatively on four height-adjustable legs or four wheels.

Electrical control via a revolving control cabinet is ergonomically located above the extruder. Because of this, a good overall view of the operating panel from every position is ensured.

Features

All of the data relevant to the extrusion can be recorded and later evaluated. Any PC is suitable to display this. For automated applications, it is possible to control the complete extruder remotely using an interface.

Options

A 45-degree adapter is available which optimises the casting point on a chill roll and is mounted between the die and the extruder. Melt pressure and melt temperature can also be displayed using a measuring ring.

The extruder can be fitted with a pressure / speed controller. Furthermore, the current torque of the driving unit can be indicated. A special on-line hopper has been designed to take only as much material as the feeding zone of the extruder can take. This way, the shortest possible reaction time of the measuring system to changes in the material quality is ensured.

Different cast film dies (50 - 150 mm) can be mounted to the extruder. Screws made of special steel with chrome-plating are available with different compression ratios (2:1, 3:1, 4:1). This allows a large range of raw materials to be tested.
