The modularity of our plastics processing technology enables a wide range of complex applications to be implemented. These include, for example, in-mould labelling (IML) for thin-walled items or the Exjection® process for long structural parts.
ARBURG offers complete turnkey solutions for the manufacture of thin-walled containers with inserts. Using the IML process, two 1-l buckets with labels and handles can be produced in a cycle time of only 4.85 s, for example. Material throughput is approximately 50 kg/h.
The containers are produced on an energy-efficient ALLROUNDER 720 H with a clamping force of 360 tons. The hybrid injection moulding machine features special packaging equipment: an extended 70-mm screw ensures a high degree of plasticizing and short cycle times. In addition, a reinforced movable platen, plus the appropriate interface for running an IML system are used.
Production of long structural components
In the Exjection® process, the mould performs a horizontal transfer movement during injection. With our vertical ALLROUNDER V injection moulding machines, this enables the production of structural components with functional geometries and integrated end caps, measuring up to several metres in length.
The control rail is produced on an ALLROUNDER 375 V. With this application, featuring a horizontally installed mould, the free space system of the clamping unit can be fully utilised. There are no limitations with regard to mould length, stroke and, consequently, component length. The servo-controlled transfer movement during the injection process is integrated in the SELOGICA control system.
