1 Speed

In the electric ALLROUNDER machines, the main axes for injection, dosing and mould opening and closing are servo- electrically driven as standard, and there-fore fully independent from one another. High acceleration and speeds combined with simultaneous movements (with restrictions on GOLDEN ELECTRIC and EDRIVE) provide for faster cycles resulting in greater cost-effectiveness.

2 Precision

In our electric ALLROUNDER machines, direct-acting play-free spindle drives ensure mechanically rigid drive axes and correspon-dingly dynamic movements. High- esolution, contactless position measurement by an ab-solute position encoder in the motor makes movement to a reference position unneces-sary. The excellent positioning accuracy of all servo-electric drives permits maximum reproducibility and part quality.

3 Energy efficiency

The high efficiency of the servo-electric drives and the toggle-type clamping unit of the electric ALLROUNDER machines ensure energy-efficient operation. The energy re-covery of the servo motors during braking also has a beneficial effect on the machines’ overall energy consumption. Together, these factors combine to reduce energy consump-tion by 25 to 50%.

4 Emission minimisation

The drives of the electric ALLROUNDER ma-chines are liquid-cooled and are therefore especially quiet. Air turbulence is avoided and the targeted dissipation of heat consid-erably reduces the amount emitted into the environment. Closed drives and spindle systems reliably prevent exposure to dust caused by abrasion. The machines are there-fore perfect for clean-room production of optical components, decorative parts, preci-sion and micro components, for example.

5 Value

A wide range of machining tasks can be accomplished with consistently high quality using the high-precision electric ALLROUNDER machines. The high degree of reliability of the machines and subsequent minimal variability in the process is achieved by numerous technical details. These include • the adaptive temperature control

for stable process conditions and• the closed cooling circuit for

motors and converters for rapid cycles and long holding pressure phases.

Emission minimisation: lower noise level.Energy efficiency: lower specific energy

consumption.

Value: long holding pressure phases thanks to

liquid-cooled motors.

Efficient machine designs

1 Innovative drive technology

The servo-electric drives with their play-free, direct-acting spindle drives on the main axes ensure precise, fast and energy-saving mo-vements. This is achieved, among other things, by energy recovery during braking. Auxiliary axes such as ejector, nozzle move-ment and core pulls may alternatively be driven hydraulically.

Innovative drive technologyThe designs of our electric ALLROUNDERs are both performance-oriented and cost-efficient: Clamping and injection units in a range of sizes can be combined with machines suit-able for all of your applications. This high level of flexibility ensures that you always achieve competitive unit costs.The GOLDEN ELECTRIC is our com-prehensively standardised entry-level model at an unbeatable price. In the case of higher requirements in terms of equipment, our EDRIVE offers additional features. And the more demanding your production tasks become, the more interesting our high-end ALLROUNDER A will become for you. The machine technology, however, always remains highly com-patible across all the machine series: the SELOGICA control system, tie-bar spacing, ejector quick-connect cou-pling and cylinder modules are identi-cal for all ALLROUNDER machines.

Extreme precision: planetary roller screw drive of

the ALLROUNDER A machines.

1 Servo-electric drives

The mechanically rigid servo-electric drives provide play-free power transmission via direct-acting spindle drives and in some cases reduction gears to enable simultane-ous, highly precise and energy-saving move-ments. In line with their relevant applica-tions, the ALLROUNDER GOLDEN ELECTRIC and E, machines feature ball screw drives, while highly stable planetary roller screw drives are used the ALLROUNDER A ma-chines. Excellent acceleration values and final speeds are achieved thanks to the high torques and rotational speeds. The closed cooling circuit for the motors and converters also plays an important role here. Conse-quently, the electric ALLROUNDER machines operate dynamically, powerfully and with extreme precision. Following start-up, they are quickly ready for operation. This is also supported by the absolute position measur-ing system of the servomotors, which dis-penses with travelling to reference positions.

The innovative drive systems of our electric ALLROUNDERs make these ma-chines reliable and powerful. In other words: highly cost-effective for your company. Despite their high dynamics, these machines operate extremely en-ergy efficiently. In essence, this is be-cause all the important moving axes are driven servo-electrically. A further ben-efit is energy recovery during braking. Furthermore, you can also opt to equip individual axes with hydraulic drives. The major advantage of this system: You can tailor your machine precisely to the requirements at hand. Precisely according to your needs, as you expect from ARBURG.

Compact alternative: small-accumulator hydraulic

system.

Maintenance-friendly: automatic central oil

lubrication of the clamping unit.

2 Integrated hydraulics

The integrated servo-hydraulics allow for energy-efficient operation of the secondary axes on the electric ALLROUNDERs. This allows serial sequences to be implemented for ejector, nozzle movement, core pulls or needle-type shut-off nozzle at an attractive price/performance ratio. The electric ALLROUNDERs can also be used for exist-ing, hydraulically operated moulds. For par-ticularly complex moulds with simultaneous sequences, an integrated small hydraulic ac-cumulator system is available as an alterna-tive on the EDRIVE and ALLDRIVE models.

3 Reliable technology

The entire servo-electric drive technology is robust, durable and wear-resistant. The au-tomatic central oil lubrication system and the grease lubrication points that converge outside the machine panelling effectively minimise the maintenance effort for the toggle-type clamping units (depending on model series and size). Because lubrication can take place during operation without in-terrupting production, machine availability also increases. Media connections and inter-faces are located on the rear of the machine to ensure easy access. The automatic mould height adjustment and good accessibility of the area around the mould, ejector and nozzle also result in significantly reduced set-up times. With this reliable technology, continuous, uninterrupted machine uptime is achieved.

Variants

For the purposes of adaptation to theapplications, various performance vari-ants are available for the ALLROUNDER A:

Performance variant L1Designed for technical parts and particularly energy-saving operation.• Performance configuration similar to stan-

dard hydraulic machine with two pumps• Regulated mould locking in two stages• Serial secondary axis movements

via servo-hydraulics

Performance variant L2Ideal for high-speed applications and complex processes.• Shorter dry cycle times and higher injection

speeds• Controlled mould locking in several stages• Functional upgrades such as injection com-

pression moulding and venting optionally available

• Simultaneous movements of secondary axes via small hydraulic accumulator system

Performance variant L3Designed for thin-walled applications and the highest demands on machine performance.• All adaptations of performance variant L2• Higher injection speeds• Reinforced mounting platens• Dosage across cycles

Precise clamping units

Practical: automatic clamping force control.

Automatic clamping force controlThe mould height adjustment effectively helps the operator to reduce set-up times. The clamping unit can conveniently be adapted to different mould installation heights. Automatic clamping force control produces a constant locking force (not available for GOLDEN ELECTRIC). This ensures that thermal expansion of the mould is fully compensated.

2 Five-point toggle system

The double five-point toggle features a sta-ble construction with multiple guidance and support points. This provides for absolutely symmetrical force application during move-ments and mould locking. Drive power and construction are also designed for heavy moulds. Despite the compact design, rela-tively large opening strokes are possible.

The toggle-type clamping unit of the electric ALLROUNDER machines oper-ates cost efficiently and with high precision. Moreover, this technology boasts highly energy-efficient run-ning characteristics, bringing you ef-fective savings on a daily basis. The kinematics of the double five-point toggle is optimally adapted to the servo-electric drive. The high-perfor-mance design of the clamping units on the GOLDEN ELECTRIC, EDRIVE and ALLDRIVE machines ensures short dry cycle times. Furthermore, the simulta-neous movements of the clamping unit and ejector significantly reduce cycle times in your production facility.

Good accessibility

3 Mould protection

The box design of the movablemounting platen is supported on the ma-chine base over the entire stroke. Together with four-tie-bar guidance, this ensures maximum parallelism and high precision. The result: optimal mould service life. Highly sensitive tie bar strain measurement is also implemented for active mould protection.

4 Precise positioning

Precise travel to the required set positions simplifies the transfer of parts to robotic systems. The spindle-driven, rigid ejector system reduces the possibility of uncon-trolled release of moulded parts as they are ejected. This enables precise, reproducible set-down of moulded parts.

5 Good accessibility

The generous tie-bar spacing allows easy handling, even in the case of large moulds. Set-up times are kept short thanks to the safety guard open at the top and the ejec-tor rapid release coupling, which is standard on all machine series. The safety guard, which has been enlarged towards the rear of the machine, offers ample space for at-tachments and media connections can be routed directly to the mounting platens.

High-quality injection units

Maintenance-friendly: easy screw changes thanks

to swivelling injection unit.

1 Wide variety of combinations

Cylinder modules that are compatible for all series and have three different screw di-ameters are available for each injection unit. Also available are cylinder modules for pro-cessing silicone, for micro-injection mould-ing plus highly wear-resistant bimetallic cyl-inders and screws with special geometries.

2 Short set-up times

The injection unit can be swivelled to the operator’s side for easy removal and cleaning of the screw and for replacing the cylinder modules. The screw can be removed without dismantling the cylinder module. Set-up can be performed quickly and without errors thanks to the screw’s rapid release coupling and the central con-nection of all cylinder module supply units.

Wide variety of combinations

Homogeneous material preparation and precise injection form the basis for high-quality part production. This is ensured, for example, by the mecha-nically rigid drive axes of the electric ALLROUNDER machines, which ensure superior process control. Added to this is the potential for energy savings, particularly through the optimised servo-electric dosage drive. With the ALLDRIVE, you maintain full control of your cycle times thanks to simultaneous nozzle movement and dosage across cycles. An additional benefit: the entire injection unit is easily accessible for set-up and cleaning work. These are all tan-gible advantages that are guaranteed to put you ahead of the competition. 2

3 Torque-free nozzle contact

The advantage of torque-free, two-tie-bar guidance of the injection units is an abso-lutely leak-free nozzle contact surface. Both flat and radius nozzles can be used without problem. High nozzle contact forces are reliably achieved thanks to cen-tral insertion in the mould. The build-up of the nozzle contact force is programmable and controlled. This has a positive effect on nozzle and mould wear.

4 Precise injection

A reproducible mould filling is achieved through several factors: servo-electric injection with force and position control, dynamic acceleration and precise measure-ment of all current pressures via paraxial sensors. The screw is reliably prevented from retracting, ensuring consistent shot weights. Liquid-cooled motors enable fast cycles and long holding pressure phases.

5 Direct dosage drive

The injection and dosage drives are mutually independent. This enables controlled back pressure. Simultaneous dosing on the ALL-DRIVE also permits short cycle times as well as longer dosage times and hence gentler melt preparation. The high overall efficiency of servo-electric drives leads to obvious ener-gy savings plus increased precision.

Application examples

Precision injection moulding: excellent

reproducibility with servo-electric drives.

1 Mass-produced medical

technology productsElectric ALLROUNDER machines are suitable for high-speed applications, such as in medi-cal technology, for example, because of their direct and dynamic servo-electric drives and high precision. Short dry cycle times are im-portant here. Simultaneous ejector and mould movements are perfectly co-ordinated to ensure reliable, precise demoulding at high speeds. The machines are also perfectly suited to use in clean rooms. This is thanks to their low-emission and smooth-running drive technology as well as the systematic omis-sion of belt drives and air-cooled motors. This ensures low turbulence and minimal particle contamination due to production processes. But customer-specific options for individual adaptations, such as V2A machine panelling are also virtually unlimited.

2 Precision injection moulding

A high degree of reproducibility, as re quired for technical parts in the auto motive indus-try, for example, is achieved in particular through the mechanically rigid drive axes of the electric ALLROUNDER machines. The excellent positioning accuracy of the servo-electric drives guarantees the smooth further processing of moulded parts in sub-sequent automated processes, especially when employing robotic systems for part removal or insertion tasks.

Mass-produced medical technology products: short cycle times for optimum unit costs.

The production of medical technologycomponents in a clean room, the high-volume manufacture of packaging items, the production of safety-critical technical parts, e.g. in the automotive industry, or of high-precision small parts at a consistently high quality level with 100% reproducibility: these are the requirements that are covered perfectly by our electric ALLROUNDER machines. With our attractive entry-level GOLDEN ELECTRIC model, the EDRIVE or the highly precise, individu-ally adjustable ALLDRIVE; our sophisti-cated technology proves its worth day after day - right in your company.

3 Optical parts

The liquid-cooled motors of the electric ALLROUNDER machines enable long hold-ing pressure phases, such as are necessary for thick-walled optical parts, for example. The servo-electric drives ensure high preci-sion. With the ALLDRIVE, all types of com-pression injection moulding are also possi-ble. The compression moulding sequence can be freely programmed via the SELOGICA control system. The starting conditions can be individually selected, for example, and compression moulding axes flexibly combined. Finally, dosing across cycles permits optimum, uniform material preparation, a reduced material tempera-ture and therefore shorter cooling times.

4 Micro injection moulding

To achieve the smallest possible shot weights, ARBURG ‚s product range includes a size 5 micro injection unit for the electric ALLROUNDER A machines. This combines an 8-mm injection screw with a second screw for melting the material. The perfect inter-play of the two screws continuously feeds the melt forwards from the material feed to the tip of the injection screw. This ensures a fully-implemented first-in, first-out method of operation. A homogeneously prepared, newly dosed melt is available for every shot.

5 Automation

The combination of ALLROUNDER machines and robotic systems forms the basis for complete production cells, which are devel-oped by the ARBURG project department together with the customer. All upstream and downstream production steps in the injection moulding process are automated. The service offerings available from ARBURG covers optimisation of moulded parts and support during the mould design process, complete assembly and commis-sioning of the individual components and installation at the owner’s premises, plus all the necessary services.
