Hydraulic machines

Wide variety of equipment and prices

Our hydraulic machines with clamping forces from 14 to 562 tons can be used for a wide variety of applications and can be individually adapted for all injection molding processes. Here, you will see our large ALLROUNDER S and the GOLDEN EDITION general purpose machine series in a variety of applications, for example.

Saw handle

Hard-soft combinations with an attractive tactile surface
A production cell built around a hydraulic ALLROUNDER 570 S uses a 1+1-cavity mold to produce handles for Gardena garden saws from 40% glass fiber-reinforced PP and soft-touch TPE (25% glass fiber-reinforced) in a cycle time of around 35 s.

The injection molding machine is equipped with a compact robot cell: an AGILUS six-axis robot, which moves on an additional linear axis transversely to the machine, is positioned above the moving platen. It removes the handles, transports them to a pad printing station and camera inspection and then sets them down on a conveyor belt. The robotic cell is easy to program thanks to the implemented SELOGICA user interface and, like the mold functions, is integrated in the machine control system.

Thumb wheel

Functional part in a single step
The cost-effective manufacture of functional components in a single step is a domain of plastics processing. Thumb wheels for passenger car interiors are a good example: Thanks to a targeted combination of materials, high-quality plastic parts with a soft-touch surface are produced.

The thumb wheels can be produced in a fully automatic process sequence on a hydraulic three-component ALLROUNDER 570 S injection molding machine. This enables efficient high-volume production of these sophisticated functional components. Initially, the translucent main body is produced from PC, then an electroplateable visible surface is added in ABS before a third, attractively tactile TPE component is injected.

Particle-foam Composite Injection Molding

Foamed part combined with plastic
Particle-foam composite injection molding (PCIM) combines a foamed insert with a polymer component. By melting the surface of the foamed insert in a defined manner when injecting the plastic, a lightweight part is produced with a durable mechanical connection, dispensing with the need for downstream assembly steps.

A hydraulic ALLROUNDER 270 C GOLDEN EDITION injection molding machine demonstrates the production of wheels for model planes. First, an EPP tire is inserted into the mold, after which a PP wheel rim is molded onto it. The 1.4 oz injection unit operates with an 18 mm screw and open nozzle . The cycle time is 3.4 s and the part weight is 3.4 g. A MULTILIFT SELECT linear robotic system ensures fast and reliable parts handling for automation purposes. Once the parts have been set down on a conveyor belt, they are packed into bags in a downstream operation.

Housing Cover

Foaming within the injection molding cycle
As a main contractor, ARBURG has, jointly with its partner Sonderhoff, developed the inline MOLD’n SEAL process, which combines injection molding with subsequent PUR foaming. This allows you to save time, costs and space, as well as significantly increasing your production efficiency.

A six-axis robotic system removes the still-warm housing covers from a hydraulic ALLROUNDER 570 S injection molding machine and moves the seal contour under a foam dosage unit, which applies the foam seal. No intermediate storage is required and the curing time is reduced significantly.
