process-controlled machines
Values of speed, path, temperature and vacuum canbe set and stored digitally. Bythis way the product qualityremains consistent and reli-able. To realize repeat orderswithout problems the com-plete process data is storedand filed.
The higher the technicallevel, the higher the outputpotential, with an easier andfaster tool change, giving thebenefit of reduced produc-tion costs.
The equipment features canvary depending on customer’srequirements and can besupplied in the most differentcombinations.
With the help of the resultingvariety, the different driveconcepts and the processcontrol the most efficienttechnology can be selected,which allows thermoforming“almost without limits”.
To guarantee a high qualitystandard of the thermo-formed parts it is necessaryto make the process-relevantparameters repeatable.
With the process-controlledsheet forming machine UA-gILLIG introduces a new gen-eration of universal thermo-forming machines, whichsets new standards as far asspeed increase and productquality are concerned. Theproduction of thermoformedparts gets new impulsesbecause the new machinegeneration of thermoformersfulfills the current require-ments of the applicant.
Different forming areas andequipment are available asoptional extras, which enablethe applicant to use the opti-mum and most economicmachine for his production.
The modular construction ofthis concept allows for combinations from the basicmachine up to the configuredprocess-controlled high- performance machine.

Product production costs toa minimumShortest conversion timesincrease the productive life ofthe machine by change offormat parts as package.
Profit maximization Preheating, off-station heat-ing, optimized cooling andtemperature control minimizethe product productioncosts, increase the outputpotential and reduce the conversion time.
All of the before mentionedelements help to meet therequired demands at a corre-sponding high quality andmaximize the profit.
As a rule splitting of heatingtime is considered and goodforming results are producedduring the very first cycle –regardless of external influ-ences.
Repeatability Parameters once determinedand stored are always available for every orderwith exact the same andunchanged values.
Temperature controlledheaters in working andresting position ILLIG’s heating philosophyfeaturing temperature controlin any heating conditionaccording to the rule: Con-trolling instead of setting.
Quality Setting data and productiondata can be printed out andstored as record for qualitycontrol of the formed parts.

Splitting of heating time The shortest cycle time isachieved, if both stationswork for the same time. Subject to the product, thisrequirement is met by splitting the heating timebetween the stations accord-ingly.
Automatic basic setting All machine setting data andfastest cycle times are estab-lished by the program. Thedata can be taken over bythe machine control andstored.

ciency. Another property ofthe servo-drives, whichshould not be underrated, isthe low energy consumptioncompared with pneumaticand hydraulic drives.
Furthermore the servo-drivesreproduce production dataat very high precision. Thisresults in high availabilityespecially of high-performancemachines or machines withfrequent format changes.The positions to be actuatedcan be stored.
An example for its use are: forming table movement,clamping frame drive, ma -terial transport and uppertable drive.
The precise and especiallyfast movements have a posi-tive effect on the productquality since for examplestretching aids can moveexactly and with definedspeed almost independentlyfrom the ambient conditions.By this way areas of preciseforming can be pre-stretchedand defined more exactlywhich results in the use ofthinner materials and thuscontributes to higher effi-
In order to guarantee long-term success for the pro-cessor, the machine has tofulfill a wide range of cus-tomer requirements. The necessary pre-conditions areeasy machine operability,flexible machine concept aswell as high repeatability ofall functional elementsinvolved in the process.

An important part plays themold when plunging into thepre-stretched material duringthe forming process.The coordination betweenpneumatic pre-stretching(pre-blowing) and the exactsynchronized table move-ments influence both theeven material distribution andthe quality of the formed partespecially in the cornerareas.
The complexity of theprocess requires differentsequences (drive variants)for forming table and pre-stretching plug.

servo-driven, with digi-tally adjustable and stor-able speed profiles for upand down travel of theforming table. Up tothree speeds can bestored as profile for eachmovement.
By this way the movementsof forming table and pre-stretching plug can be precisely harmonized. Thecycle time is reduced by different speeds.
In order to obtain a moreeven wall thickness, pneu-matically pre-stretching of the heated material is necessary.
This is done by pre-blowingthe sheet. For this, controlledair flows into the formingchamber (blow box). A photo -cell controls the resultingbubble. This ensures a constant repeatable productquality by more even dis -tribution of wall thickness.The final geometry of theformed part is achieved bydefinition by vacuum.
In order to consequently usethe possibilities of themachine in practice, thecomplexity of the processrequires specific operatorguidance on the screen.

An upper and lower heatercan be installed in the load-ing device. This possibilityprovides pre-heating or off-station heating of the ma -terial and allows for reductionof cycle time. Subject to thebehavior of the material andthe machine equipment theheating time, which rules thecycle time, can be reducedin the forming station up to0 seconds.

Intelligence based on PC
Today high demands aremade on productionmachines with regard toaccuracy and repeatability.This is the only way to meetthe high quality standards forformed parts. This meansthat thermoforming machinesmust have properties, whichare already standard on the3rd generation machines.
The control systems andcontrol strategies developedby ILLIG ensure easy produc-tion sequences at high avail-ability and operator comfort.
Process control
Compensation methods forrepeatability of temperatureprofiles through out the thick-ness of material.
Advantage of this equipment:Both the surface temperaturesas well as the core tempera-tures of the material are considered, which cannot bemeasured in the productionmachine. Since it is not possi-ble to measure the core tem-perature of the sheet, it is calculated in the background.This way the temperature pro-file can be kept on constantlevel all through the cross section of the sheet. Subject to the requirement,temperature of heater ele-ments or heating time arecontinuously automaticlyadapted so that all influenceslike temperature of the stands,ambient temperature and ini-tial temperature of the materialare considered automaticly.

with the help of the alreadyknown “computer-aidedbasic setting”. The settingdata and process timesdetermined herewith can beoptimized to such an extentthat the machine sequencingcan be adjusted to theformed part to be produced.There will be a performanceincrease affecting the cycletime without loss of productquality.
By combining all process relevant parameters the defi-nition and distribution of thewall thickness can be influ-enced repeatedly in the side-wall.

Upper table, furtherdevelopments
In the last few years, de-velopments were made,which considerably improved efficiency of the sheet processing machines evenfor smaller quantities.
In order to use the advan-tages of thermoforming to itsoptimal extent different driveconcepts are available for theupper table.

The smooth and even heat-ing up of the material is thekey for a good forming result.The heaters are equippedwith high temperatureceramic heater elements(HTS). These elements arehollow, have thermal insula-tion and a high degree of efficiency.
They have universal heatingproperties, i.e. preprintedmaterials, too, can be uni-formly heated. The heatingtimes required are not sub-ject to the color of the ma -terial. For high efficiency theradiation surface is closed.This ensures good heatingresults for every clampingframe size up to the edgearea. Upper and lower heaterprovided with Joystick division for heater area ispart of the basic equipment.
Thereby an optimal heaterlayout is achieved for thethermoforming process. Thetemperature control of theheaters is carried out by sev-eral pilot heater elementsand overlapping perfor-mance.
With the help of the heaterlayout set by the basicadjustment program as wellas with all sequence times,an almost even temperaturedistribution is achieved onthe heated material, which issufficient for the most fre-quent applications. If neces-sary, the heater layout can bechanged very easily. Apartfrom that the machine can beequipped with IR measuringtechnology.

These profiles form the lowertool together with the sup-port plate of the segmentand the actual mold. Such atool can then be used on alltable variants.
ILLIG has developed a man-ual for construction of moldsand tools, which enables theapplicant to make simpletools by himself. This savestime and reduces costs forformat parts.
Reduced change times fortool and format parts, simpli-fied operation and higheravailability are further advan-tages of the sheet processingmachine from ILLIG. As aconsequence the times suchas sheet and tool change aswell as maintenance arereduced to a minimum.
The unique tool and standardparts system for constructionof forming tools in connec-tion with the adjustable moldsubstructure offers specialadvantages for the produc-tion of small series with frequent format change. Themold substructure can bemade very easily with thehelp of the standard profilesP19 and P20.
The conversion program supports the operator and enables automatic toolchange in all stations.
Availability and productivity have priority
If on the more simplemachine the tool change procedure is mainly carriedout manually, the automaticquick-change of tool reducesthe conversion times for allmachine sizes.
The complete mold package(forming tool, upper andlower clamping frame incl.plug assist) is moved in viathe front panel. Pairs ofrollers facilitate loading of thetool package into the blowbox.
The forming tool centersitself automaticly and isclamped by vacuum onto theforming table. This clampingvacuum is controlled auto-maticly. Upon closing thefront panel the individualfunctions run down auto -maticly by the conversionprogram, e. g. upward travel

The machine provides theoperator with the relevantparameters, which proceed-ing is displayed on the oper-ating panel. An importantadvantage of this visualiza-tion is the specific display ofthe required information andauxiliary functions followingthe principles of the pro -fessional industrial design.

Temperature control by ITS-System
The ITS-System permitsfield-proven temperaturecontrol of clamping and hold-ing frames as well as of theforming tool. It is also possi-ble to have different temper-atures within the forming toolor the upper table tool (e.g.twin-sheet). Depending onmaterial and application tem-perature modules up to 95°C
Cooling systems
On the one hand a largequantity of energy has to befed for the forming process,which on the other hand hasto be dissipated after theforming process by the cool-ing systems in a useful wayand in the shortest possibletime. The combination of theindividual cooling systemssuch like tool cooling, airshower in upper frame andcooling fans have the mostefficient effect, which thencan directly be convertedinto performance.
On account of cooling fanswith reinforced performanceand its freely configurablecombination high air speedsare achieved where water-spraying nozzles no longerare necessary.

Multiple position switchingfor upper heater and Joystickdivision for lower heater arepossible. In order to form theundercuts or to form theintermediate bridges auxiliaryplugs or sectional coolingdevices (corner blowing nozzles) can be used. Corre-sponding devices can becontrolled synchronouslywith the forming process bythe plug assist device
On account of this device airis specifically blown onto thewarm sheet during the pre-blowing process. Thosezones blown at cool downand are therefore stretchedless. This means that thesezones remain thicker. The airstream used can be regu-lated and controlled. Theadvantage of this technologyis to avoid marks on theformed part.
To demold indentations orundercuts correspondingloose parts or slides in theforming tool are used. Thesecan be actuated by theformed part itself, subject tosufficient rigidity, or by a con-trol unit depending on timeand distance. Correspondingcontrol elements areattached to the machine.
