1 Speed

In the electric ALLROUNDER machines, the main axes for injection, dosing, and mold opening and closing are servo-electri-cally driven as standard, and therefore fully independent from one another. High accel-eration and speeds combined with simulta-neous movements (to a limited extent 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 corre-spondingly dynamic movements. High-reso-lution, contactless position measurement by an absolute position encoder in the motor makes movement to a reference position unnecessary. The excellent positioning accu-racy of all servo-electric drives permits maxi-mum 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 recovery 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 up to 50%.

4 Emission minimization

The drives of the electric ALLROUNDER machines are liquid-cooled and are there-fore especially quiet. Air turbulence is avoided and the targeted dissipation of heat considerably reduces the amount emit-ted into the environment. Closed drives and spindle systems reliably prevent exposure to dust caused by abrasion. The machines are therefore perfect for clean room production of optical components, decorative parts, pre-cision 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 subse-quent 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 minimization: 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 movements. 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 standard-ized model which is comprehensively equipped and available at an unbeat-able price. In the case of higher require-ments 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, how-ever, always remains highly compatible across all the machine series: the SELOGICA control system, tie-bar spac-ing, ejector quick-connect coupling and cylinder modules are identical for all ALLROUNDER machines.

Innovative drive technology

Extreme precision: Planetary roller screw drive of

the ALLROUNDER A.

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 intended applica-tions, the ALLROUNDER GOLDEN ELECTRIC and E, machines feature ball screw drives, while highly stable planetary roller screw drives are used exclusively on the ALLROUNDER A machines. Excellent acceler-ation 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 impor-tant role here. Consequently, the electric ALLROUNDER machines operate dynami-cally, powerfully and with extreme precision. Following start-up, they are quickly ready for operation. This is also supported by the absolute position measuring system of the servomotors, which dispenses with traveling to reference positions.

The innovative drive systems of our electric ALLROUNDERs make these machines reliable and powerful. In other words: highly cost-effective for your company. Despite their high dyna-mics, these machines operate extremely energy efficiently. In essence, this is because all the important moving axes are driven servo-electrically. A further benefit is energy recovery during bra-king. 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 ALL-ROUNDERs can also be used for existing, hydraulically operated molds. For particularly complex molds with simultaneous sequen-ces, an integrated small hydraulic accumula-tor system is available as an alternative 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 paneling effectively minimize 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 in-terfaces are located on the rear of the ma-chine to ensure easy access. The automatic mold height adjustment and good accessi-bility of the area around the mold, ejector and nozzle also result in significantly re-duced set-up times. With this reliable tech-nology, continuous, uninterrupted machine uptime is achieved.

Variants

For the purposes of adaptation to theapplications, various performance variants 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 mold 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 mold locking in two stages• Functional upgrades such as injection

compression molding 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 perfor-mance.• 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 mold height adjustment effectively helps the operator to reduce set-up times. The clamping unit can conveniently be adapted to different mold installation heights. Automatic clamping force control ensures a regulated and constant locking force (not available for GOLDEN ELECTRIC). This ensures that thermal expansion and contraction of the mold is fully compensated.

2 Five-point toggle system

The double five-point toggle features a stable construction with multiple guidance and support points. This ensures completely symmetrical force application during move-ments and mold locking. Drive power and construction are also designed for heavy molds. 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 running characteristics, bringing you effective savings on a daily basis. The kinematics of the double five-point toggle is optimally adapted to the servo- electric drive. The high-performance design of the clamping units on the GOLDEN ELECTRIC, EDRIVE and ALLDRIVE machines ensures short dry cycle times. Furthermore, the simultane-ous movements of the clamping unit and ejector significantly reduce cycle times in your production facility.

Good accessibility

3 Mold protection

The elongated box design of the moving mold platen is supported on the machine base over the entire length of the stroke. Together with four-tie-bar guidance, this ensures high precision. The stable clamp-ing unit and active mold protection system with its extremely sensitive tie-bar strain measurement ensure optimum service life of the mold.

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 molded parts as they are ejected. This enables precise, reproducible set-down of molded parts.

5 Good accessibility

The generous tie-bar spacing allows easy handling, even in the case of large molds. Set-up times are kept short thanks to the safety guard open at the top and the ejec-tor quick disconnect 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 attachments, and media con-nections can be routed directly to the mounting platens.

High-quality injection units

Maintenance-friendly: easy screw changes thanks

to swiveling 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 molding plus highly wear-resistant bimetallic cylin-ders and screws with special geometries.

2 Short set-up times

The injection unit can be swiveled to the operator’s side for easy removal and cleaning of the screw and for replacing the cylinder modules. The screw can be re-moved without dismantling the cylinder module. Set-up can be performed quickly and without errors thanks to the screw’s quick disconnect coupling and the central connection 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 en-sured, for example, by the mechanically 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 optimized servo-electric dosage drive. With the ALLDRIVE, you maintain full control of your cycle times thanks to simultaneous nozzle movement and dosage across cy-cles. 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 the torque free, two-tie bar guidance of the injection units is the absolutely leak-free nozzle contact. Both flat and radius nozzles can be used without problem. High nozzle contact forces are achieved with ease thanks to central inser-tion in the mold. The build-up of the nozzle contact force is programmable and con-trolled. This has a positive effect on nozzle and mold wear.

4 Precise injection

A reproducible mold filling is achieved through several factors: Servo-electric injec-tion with force and position control, dy-namic 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 ALLDRIVE also permits short cycle times as well as longer dosage times and hence gent-ler melt preparation. The high overall effici-ency of servo-electric drives leads to obvious energy savings plus increased precision.

Application examples

Precision injection molding: excellent

reproducibility with servo-electric drives.

1 Mass-produced medical

technology productsElectric ALLROUNDER machines are suitable for high-speed applications, such as in med-ical technology, for example, because of their direct and dynamic servo-electric drives and high precision. Short dry cycle times are important here. Simultaneous ejector and mold movements are perfectly coordinated to ensure reliable, precise demolding at high speeds. The machines are also per-fectly suited to use in clean rooms. This is thanks to their low-emission and smooth-running drive technology as well as the systematic omission 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 paneling are also virtually unlimited.

2 Precision injection molding

A high degree of reproducibility, as required for technical parts in the automotive 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 molded 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 levelwith 100% reproducibility: these are the requirements that are covered per-fectly by our electric ALLROUNDER ma-chines. With our attractive standardized GOLDEN ELECTRIC model, the modular EDRIVE or the high-performance, indi-vidually adjustable ALLDRIVE; our so-phisticated 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 pres-sure holding 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 molding are also possible. The compression molding sequence can be freely programmed via the SELOGICA con-trol system. The starting conditions can be individually selected, for example, and com-pression molding axes flexibly combined. Finally, dosing across cycles permits opti-mum, uniform material preparation, a re-duced material temperature and therefore shorter cooling times.

4 Micro-injection molding

To achieve the smallest possible shot weights, ARBURG ‚s product range includes a 0.1 oz micro injection unit for the electric ALLROUNDER A machines. It 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 inlet to the tip of the injection screw. This ensures full implementation of the first-in, first-out principle. 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 molding process are automated. The service offerings available from ARBURG covers optimization of molded parts and support during the mold design process, complete assembly and commis-sioning of the individual components and installation at the owner’s premises, plus all the necessary services.
