EcoPower The system-highlights
》Directservodrivesformainmovements
The EcoPower machines come with highly dynamic servomotors to drive the main movements(closing/ opening, plasticizing, injection). The mold height adjustment devicein the clamping unit isalso driven by a servo-electric motor.The ancillary strokes(ejector, nozzle stroke/contact pressure,core pulls) are driven by an integrated servo-hydraulicaggregate powered by aservo-electricmotor.Directservo-mechanicdrivesare available as an option.
》High-performanceinjectionunit
The EcoPowerinjectionunits are equipped with a twin drive systemfortheinjection and dosingfunctions.A torsion-resistant,one-piece cast iron frame with linear guides and acentralballscrewdriveprovidesthebasis for highly dynamic, precise movements.
》Fasttoggle clamping system
TheEcoPower clampingunit isa3-platen/4-tie-bar systemwith a5-point toggle lever,driven directlyby aservo motorviaa rack-and-pinion drive.The moving platen of the machine travels on linear guides and rotating roller bearings without coming into contact with the tiebars.Injection can alreadystart during clamping force build-up.
》KERS-energy recovery is standard
TheKERSkineticenergyrecoverysystempatentedor injectionmolding machines,converts thekinetic energyreleasedbybraking processes intoelectricalenergy. The resulting current is used within the machine,e. g. for barrel heating.With KERS,the energy consumption can be cut further by up to 5%
》MouldProtect-fast-responsemold protection The minimal rolling friction of themoving platen guide systemcombinedwithmeasurementofforcechanges insidethetoggleleverdriveoffersoptimalconditions forhighlysensitive,selflearning,fast-response mold protection.
CLAMPING UNIT Servo-electric speed and dynamism
》Amplespaceforcomplexmolds
Generouslydimensioned moldplatens[1]and a cleantogglelever clamping system offer the optimal environment for all molds includingallmediaconnections. The ejector area and the environment of the platens offer easy access for machine setup and adjustment work.[2]
》Sensitive andprecise
In theEcoPowerclamping system,thetie-bars are exclusively used for forcetransmissionbetweentheouterplatens.Themovingplatentrav elsvirtuallyfree of friction across the linearbearings without coming into contact with the tie-bars.[3]
》Servo-electricdynamism
Themovingplatenismovedquickly andwithhighprecisionbya self-locking 5-point togglelever.[4]
The toggle lever is driven by a highly dynamicservomotorvia a rackand-pinion drive system.[5]
Thesynchronizedmoldheightadjustmentvia4bronzebarnuts and a sun gear system is driven by a servo motor.In this way,an extremely accurate clamping force regulation canbe achieved. [6]
》Servo-hydraulic ancillary strokes
To drive the ancillary strokes (ejector, nozle strokes and core pulls), a hydraulic aggregatepoweredby a servo-electricmotorismounted on theinside of themachine frame.Being specially designed forhigh efficiency,it requires no cooling water connection.The maintenance-friendly access is from the rear,behind the clamping unit.Servo-mechanical drivesfor the ancillary strokes are available as options.
