DL A5 series

Servo hydraulic two platen technology

  • Two-platen plastic injection moulding machine series developed in Austria
  • Energy-efficient servo hydraulic drive with European components
  • The machines with two-platen technology are equipped with controls by B&R
  • Very broad range of clamping forces from 4500 to 43000 kN

New energy concept „developed in Europe“

DL-A5-machines are serially equipped with a servo hydraulic drive unit. This permits a very low energy consumption, since this servo hydraulic power is only called on demand.

The DL650A5, a hydraulic two-platen machine with a clamping force of 6500 kN, for example, has a dry-running time of less than 3 seconds. According to the EUROMAP 60.1 measurement, the energy efficiency coefficient is given as 8.

Energy efficiency has clearly been improved by hydraulic elements placed very close to the injection cylinder and servo pumps placed right by the oil tank. This arrangement reduces power demand by minimising power loss.

The hydraulic system is easily accessible for service tasks and thus very maintenance-friendly.

Powerful double cylinder injection unit

The injection units are moved by powerful double cylinders with linear guided supports. They ensure quick, precisely positioned and accurate movements. They are supplemented by pull double cylinders for applying the nozzle tip to the mould. Many volumes are available as injection units, ranging from 1278 cm³ to 71675 cm³. The bandwidth of injection rates ranges from 407 cm³/s to 3290 cm³/s.

Optionally, special screw concepts or specially hardened screws for particularly abrasive or corrosive materials can be used.

 


Fast and efficient clamping concept

An efficient two-platen clamping system ensures powerful and dosed movements of the clamping mechanism. Based on strong linear guidance of the moving platen, it permits quick opening and closing in the cycle. Position measuring systems record the current position of movement along the moving platen continually.

The FEM-calculated tie bar design ensures a fast synchronized locking. The Design of the platens - also developped by using FEM - ensures best platen parallelism. Generous mold clamping sizes by large tie bar distances and an automatic tie bar retraction device complete the concept of the series. The model pallet is made up of clamping force values 4500 kN, 5500 kN, 6500 kN and 8500 kN in the middle clamping force range. The upper league of clamping forces offers finely graduated models with clamping forces of 10500 kN, 13000 kN, 17000 kN, 18000 kN, 20000 kN, 23000 kN, 25000 kN and 27000 kN. The four strongest models have clamping forces of 30000 kN, 33000 kN, 40000 kN and 43000 kN. Users can choose between 16 finely graduated models in space-saving two-platen technology for every production task.

 

 

Automatic tie bar retraction device for large molds

The DL-A5 series has an optional automatic tie bar retraction device for special mold concepts. This permits the installation of over-sized and very large molds as well. The automated tie bar retraction system with FEM-optimised tie bars is guided by an integrated frame stably and precisely positioned.

Flexible arrangement of the tie bar retraction device

The tie bar retraction device can be arranged either at the rear side of the machine or the operator's side.
