Volumetric dispensing

The mta® high-precision volumetric dispensers offer the most accurate volume controlavailableinthefluiddispensingindustry.Theyenableperfectrepeatabilityofmicro-volumestobedispensedstartingwith0.1mm³.

Thepumpingunitmaintainsaccuracy in themostdemandingof circumstances independentlyfromchangesoftemperature,viscosityordepositsize.Themta®dispensersarebasedonapistonthatmoveswithinthedispensingchambertodeliver an exact quantity of fluid through the nozzle. The working principle is describedonpage5.

Before choosing the most appropriate dispensing technique, the customer’s applicationisstudiedinthemta®testlaboratory.Duringthesefeasibilitystudies, propertiessuchasspecificdensityofmaterialtobedispensed,mixingratioandviscosityareanalyzed.

Byusingmta® techniquessuchasvolumetricdispensing for two-componentormono-component products, standardized automated solutions are proposedfor all the customer’s specific applications. These techniques are detailed on pages6,7and8.

The dispensers can be integrated into the various mta® standard platforms, adaptedfor fullyautomaticorsemi-automaticoperations,suchas theMRC500 roboticcell,theTR300table-toprobot,theOEMrobotorthestation.Thedispensingplatformsaredetailedonpages9to14.

Pump working principles

Thebasicworkingprinciplesofthepumpcombinesalinearmovementtodefine thequantityofmaterialtobedispensed(see2and4inthepictureontheright)andarotatingmovement(see3inthepicture)totransferthematerialfromthepumpinputtoitsoutput.

The accurate pump assembly can be divided into different leak rates in order tobeperfectlyadaptedtodifferenttypesofmaterialcharacteristics.Thissolutionishighlypreciseandalwaysvolumetric.

Picturelegends:1.Homeposition,2.Fillingstroke,3.Rotation,4.Dispensingstroke andsnuffback.

Continuous flow dispensing

Theconstantflowrateisachievedthroughprogressivecavitypumpandinvolvesthe eccentric rotarymotion of a stainless steel helical rotor into an elastomer stator.Duetotheirpreciseandcomplementarygeometries, therotationof therotor in the stator generates fixed-size sealed cavities which are continuously conveyed forward up to the discharge end. The suction resulting from this movementpullsthefluidintothesealedcavitiestowardsthedispensingnozzle.The volumetric flow rate is therefore proportional to the angular speedof the rotorandiscontrolledwithahighdegreeofaccuracy.

Duetotheroundedgeometryofthecavities,lowshearratesareappliedtothedispensingfluid,thusallowingtodispenseshearsensitive,thixotropeandhigh-viscousmaterials.

Mixing chambers

The mta® mixing chamber is a unique solution on the market based on a dynamicmixingchamber.Thisunitmadeofstainlesssteelandplastichasbeen designed to either be cleaned or changed after use depending on the mixed material type. In terms of maintenance of the whole equipment, it is a clear advantagetohavethematerialbeingmixedjustbeforedispensing.Thedispensingnozzlesaredirectlyconnectedtothemixingchamber.

This chamber homogeneously mixes A and B material by using a rotating blender. In order to optimize the mixing effect, the rotational speed can be electronicallycontrolled.Thissolutionisperfectlyadaptedtosmallvolumes.Themixingqualitycanbeachievedbyadaptingmixingtime,mixerspeedandmixingchambervolume.Fourstandardmixingchambersizesareavailable:200,600,1500and2300.
