SETUP

PRODUCTION

》Production

In the standard version,thedosing and injection processes and themelt cushionvolume are monitoredby stroke-based measured valueintegrals withupto400measurement points within adjustable limit values.Wheneverthetolerancelimits areexceeded, an alarm is triggered which requires an intervention by the machine operator.A similarfunction isin place formold protection.Optional HiQ programsfor process control are also available.

》Quality management

Forquality monitoring,a quality data tablewith display andmonitoring of 6 parameters and 1000 events is available as standard, plus5graphic curves of actual values and one envelope curve.One option is the expert package with an extensive range of additional functions.Another is the HiQ process control package.

MACHINESETUPInitial parameter setting via QuickSetup

QuickSetup

The QuickSetup assistance program is the machine version of the"WIBA-Assist”mobile app.It offers the advantage of quick,easy programming of the production system's initial parameter settings.

Following the selection of the material data from the database within theB8 and entry of the mold dimensions, the program automatically calculates an initialsetting whichcanbetakenoverforproduction start-up.

IndividualsequencescanbesetinSmartEditfor all movements not included inthe general initial setting.QuickSetupoffersahelplibraryforcycle optimization and for solving problems in the process sequence.

The advantages

Process-oriented machine setting
》 Initial settingbased onmaterialdata
》 Entry of the most important mold dimensions is the only additional data input required.
x The calculatedinitialsettingscanbe taken over directlyinto the machine cycle.

SmartEdit

SmartEdit is avisual,icon-based cycle sequence programming facility,whichenables direct addition of special functions(core pulls, air valves, etc.) based on a standardprocessvia touchoperation on the screen.In this way, a total user-defined sequencecanbe compiled from a sequencemenu. This machine cycle,visualized eitherhorizontally or vertically,can be adjusted simply and flexibly to the process requirementsby fingertouch with"Drag & Drop" movements.

The advantages

》Icon visualization ensures clarity.
(3) Clear events sequence through node diagram
y Alterations without consequences through"dry test runs"
\gg Theoretical process sequence can be quickly implemented in practice.
》Automaticcalculationof the automation sequencebased on the actualset-up data set without machinemovements

APPLICATIONTECHNOLOGYSOFTWARE Comprehensive programs for standard and as option

In the standard version,the machine's control system already comes withan extensive package of applicationsoftware,whichenablesoptimization of the cycle sequence and an increase in process accuracy.

_{\Rightarrow} Melt Monitoring (monitoring of doses)
\gg FlowMonitoring(injection integral monitoring)
(3) Cushion Monitoring (monitoring of the melt cushion)
(3) Pre-Shut (closing of the check valve by counterrotation-EcoPower)

Process monitoring is based onrecords of strokerelated measurement integrals with up to 400 measuringpoints.Each integral value exceeding or fallingbelowthetolerancemargintriggersan alarm signal and requires intervention by the machine operator.

\gg Mould Protect -highly sensitive mold protection (for EcoPowerand MicroPower) The highly sensitive,self-learning mold protection function is derived from sensitive motorspeed measurementandmonitoring oftheservo-electric clamping unit drive.

》BasicStepForce-Injection parallel to clamping force build-up. (for EcoPower und MicroPower)

》Basic Coining － standard compression molding program (for SmartPower and MacroPower) The sequential standard coining program isa high-precision strokecontrolsystem of the clamping unit,suitableforapplicationswithsymmetrical forcedistributioninside themold.

_{\Rightarrow} Basic Quality Monitoring

HIQ SOFTWARE (OPTION) Compensates environmental factors

》HiQ Melt

monitoring of material quality

HiQ Melt is a method of monitoring material quality.Its key parameter is the plasticizing energy.It ismeasured by the screw torque in relation to the plasticizing stroke,shown as a numericalvalue andmonitoredwithina settolerance margin.Deviationsin material quality an be detected easily and recorded.

》HiQ Flow

material viscosity quality-related injection control

HiQ Flow uses the melt compressibility and the pressure datafrom theinjection curveto calculate aparameterproportionaltothecomponent weight,the so-calledSMUVinjectionvolume (SMart Uncompressed Value).The pressure and strokedataarerecordedandtheSMUVvolume is calculated every2milliseconds along the injection stroke.The calculatedSMUVvolume is used to control theswitchoverpoint and/orthe holding pressure phase.External material data is not necessary,since all necessary material parameters are determined during a production cycle.Viscosityfluctuations due to,e.g.the use of regrind or batchfluctuations can thus be compensated for and enable robust production and component quality

》HiQ Cushion

melt cushion control

This melt cushion control system is able to recognise trends in the change of the cushion length due to viscosity fluctuations or wear in the checkring assembly and to compensate it within certain limits.For the purpose, the length of themelt cushion ismeasured at theend of the injection process,and if required,the plasticizing stroke is adjusted within the next cycle.

》HiQ Metering

Active closing of the check valve

Between metering and the decompression stoke, the checkring is depressurized and brought into the"closed" position by targeted movements of thescrew.Sothe checkvalveis alreadyclosed before the injection phase starts.Even the smallest metering end point deviations arerectified by shifting the injection profile and the changeover point.In this way,exactly the required amount ofmaterialisinjectedwitheveryshot,which ensures the highest possible consistencyin part weights.

EXPERT SYSTEMS (OPTION) Intelligent clamping unit

》Expert-Coining(for EcoPower) High-precision coining and mold opening with the servo electric clamping unit

Expert-Coining (for MacroPower) High-precision coining and mold opening includingparallelism control andparallel operation of all four tie-bar pressure pads.The coining process is carried out volume-controlled(depending on screw position).Thanks to high-precison mold opening,structured foaminjectionmoldingis also possible.
