ALUCOBOND® is a prefabricated panellingmaterial, i.e. the surface of the standard panelis either lacquered, anodised or mill-finished.These surfaces are protected by a special foilduring transport, storage and processing.Nevertheless, the following information mustbe observed when storing and handling thepanels:

• The pallets must be handled carefullyduring transport and unloading.

• Upon delivery the pallets must be examinedfor any damage due to moisture (ALUCOBOND®

panels that have become wet must be dried toavoid any spots or corrosion forming). Anydamage must be reported immediately andconfirmed by the forwarding agent.

• Store the pallets so that they are protectedagainst any wetness penetrating due to rainand spray water and avoid any condensationforming (e.g. when transporting cold panels towarmer rooms).

• Store the pallets stacked one over the other(do not store ALUCOBOND® panels standingvertically), with a maximum of 6 pallets of thesame format stacked on top of each other(heavy pallets at the bottom).

• Individual panels must be lifted off the pal-let by two people holding all four corners andnot drawn over each other. Carry the panelsvertically. Wear gloves to avoid making anymarks on them.

The following should be observed asregards the ALUCOBOND® protective foil:

• Storage exceeding 6 months should beavoided.

• Strong fluctuations in temperature reducethe long-term durability.

• Should the protective foil partially come offduring processing, dirtied edges can occur inthe course of time.

RoutingALUCOBOND® can be easily routed on conven-tional routing machines and CNC machiningcentres. To avoid pressure marks on the ALUCOBOND®

surface, please use plastic or wood vice jawswhen chucking the workpieces. High-speed steel or carbide tipped cutterssuitable for aluminium and ALUCOBOND®

have a wide tooth pitch, radiused and smoothgrooves and small lip angles.They produce perfect cuts, e.g. under thefollowing conditions:

• High-speed steel max. cutting speed max. 3,000 m/min.feed max. 25 m/min.

• Carbide tipped cutter max. cutting speed max. 5,000 m/min. feed max. 30 m/min.

DrillingALUCOBOND® can be drilled with twist drillsnormally used for aluminium and plastics onmachines common for metals.Drill material: High-speed steel (HSS)Tool geometry: Lip angle: 100 ° – 140 °Drilling without burr is possible using the fol-lowing drills:spot facing cutter with centre-point.Angle of whist: 30 ° – 45 °e.g. Extreme 2TM HSS-G Metal drill DIN 338 ofDe WALT, D-Idstein

CountersinkThree-lipped core drills and counterborescommon for aluminium are used for counter-sinking pre-drilled holes. Counterbored holesare less out of centre than those produced bytwist drills. Countersinks for aluminium can beused for countersinking flat head screws intoALUCOBOND®. Head and shank counterboresfor aluminium are mainly used for countersink-ing screw heads or for making holes throughALUCOBOND®.

Contour cuttingALUCOBOND® can be cut to size with jigsaws, CNC machining centres and watertorches. Please cut abrasively when using awater torch. Pre-drilling of the panels is nec-essary when starting the cut in the middle ofa panel as it is not possible to drill throughwith a water torch.

ShearingALUCOBOND® is easily sheared with a guillo-tine. A slight drawing of the aluminium coversheet caused at the impact side should benoted. The clamp on the shear should be fittedwith a shock-absorbing rubber pad to preventdamage to the cover sheet.

PunchingALUCOBOND® panels of any thickness can bepunched with conventional sheet punchingmachines. For clean cuts please use evenlyground tools and the narrowest possible cut-ting gap (0.1 mm). This punching method alsocauses a slight drawing of the panel coversheet. Holes of a minimum diameter of 4 mmcan be punched. The minimum width of webbetween hole edges is also 4 mm.

BendingALUCOBOND® can be formed by conventionalmetal and plastic fabrication methods. Certainspecific points should be noted relating to themultilayer structure combining materials ofdifferent characteristics:

• The minimum radius isfor ALUCOBOND® and ALUCOBOND® PLUS r = 10 x tfor ALUCOBOND® A2 r = 25 x tt = panel thickness

The spring-back effect experienced when fold-ing sheet metal is larger with ALUCOBOND®.For production series a prototype should bemade.The surface should be protected from damageby affixing plastic film or inserting polyethyleneof 1 – 2 mm thickness or plastic film stripsduring processing.The panel surface must be free from anyadhesive material (e.g. labels, etc.).Important:When bending ALUCOBOND® with ananodized surface, the bent area is brighter.

Bending with a brake press(Fig. 1) ALUCOBOND®, like sheet metal, is easilyformed with a brake press. The air-bendingprocess is used when forming with a brakepress. The ALUCOBOND® panel rests on the edges ofthe die (rails, channels) and is bent by thepunch (tube or shaft). The bending angle isdetermined by the width of the die and thestroke of the punch. The die edges should berounded and smooth.Ideal die width:2 x t + 2 x protective foil thickness + punch diameter + 15 mmThe minimum side length of the bent partshould be 5 times the ALUCOBOND® thickness.

Bending with a folding machine(Fig. 2) When working with folding machines, thepanel to be bent is clamped between twocheeks. The projecting edge is bent aroundthe upper clamping cheek and former usingthe movable swivel bar. The bending radius isdetermined by interchangeable formersattached to the upper clamping cheek.

Bending with a roll bending machine

ALUCOBOND® can be bent with sheet metalroll bending machines – mainly with three andfour-roll machines. Please make sure that thefeeder does not exert too much pressure.Bending rolls which are also used for bendingother metals must be thoroughly cleaned fromswarf before processing ALUCOBOND®. Werecommend ground rolls to avoid damagingthe cover sheets.

Routing and Folding Technique

and Designfor individual Shaping

AdvantagesThe convincing advantages of the routing andfolding techniques are:• Minimum investment• Simple operating technique• Folding need not be done in the workshop,

it can be done on site; this means lowtransport and storage costs

• Low-cost manufacture of shaped parts likefascia claddings, roof edgings, corner pieces,column casings and many more are possible

• Versatile formability• Good economy• Shapes are not restricted by machine

dimensions• Folding without cutting, therefore no

buckling in the corner area and thus evenelements

Rectangular groove for edges up to 150° depending on panel thickness

Groove 135° (V-shaped) for edges up to 135°

MethodALUCOBOND® composite panels can beshaped by means of a simple processing tech-nique. This procedure, the routing and foldingtechnique, enables a variety of shapes andsizes to be manufactured.V-shaped or rectangular grooves are routed onthe rear of the panels with disk or end millingcutters, whereby the aluminium cover sheet atthe front and part of the polyethylene core areretained. The small thickness of the remainingmaterial then allows folding by hand. A brakepress is not required. The groove shape deter-mines the radius of the bend.The grooves can be produced with a panel sawwith routing device for ALUCOBOND®, on aCNC machining centre, with a panel routingmachine or a hand routing machine. The rout-ing and folding technique can be used forcomposite panels of all standard surfaces.Important:When folding ALUCOBOND® with an anodizedsurface, the edges are brighter.

Jointing /

TechniqueFixing

ALUCOBOND® can be joined by means ofstandard processes used in metal and plasticstechnology. If ALUCOBOND® is to be joined to structuralparts of metals other than aluminium, or iffasteners (e.g. bolts, screws) are to be used,the following material guidelines should beobserved:Fasteners and structural parts made of alu-minium, plastic or stainless steel should besuitable for the assembly with ALUCOBOND®.When using other materials please insertinsulating washers etc. or apply protectivecoating to prevent corrosion.

Please take the thermal expansion of the panelinto account for outdoor use of ALUCOBOND®

to avoid jamming or deformation.The minimum gap depends on the expectedexpansion of the panel.Please refer to processing recommendationsfor rivets and bolts for additional measures toprevent jamming.The linear thermal expansion of ALUCOBOND®

is determined by the aluminium cover sheets. At a temperature difference of 100°C thethermal expansion is 2.4 mm/m.

16

ALUCOBOND® panels can be fastened togetheror joined to other materials with rivets commonto aluminium constructions.For outdoor use and for use in areas of highhumidity, aluminium blind rivets with stainlesssteel mandrils should be used to prevent uglycorrosive edges. When using aluminium blindrivets with steel mandrils, the mandril shoulddrop out after riveting (detachable version).Countersunk rivets are suitable for indoor useonly.

For outdoor use please note:• For outdoor use aluminium blind rivets thathave been approved for construction with a 5 mm shaft diameter and an attachment headdiameter of 11 or 14 mm are used.• Please take the thermal expansion of thepanel into account (2.4 mm/m/100°C). Toavoid jamming, the hole in the panel must belarge enough to allow for expansion.• With the shaft of the rivet fitting closely tothe edge of the hole, the attachment headmust cover over 1 mm of the area surroundingthe hole.• Multi-step drills or sleeves having corre-sponding diameters are used for centricallydrilling holes into the panel and the substruc-ture and for centrically fitting the rivet.• Rivet attachment jigs are used for fittingblind rivets without jamming allowing for atolerance of 0.3 mm. Make sure to use rivetattachment jigs and rivets from the samemanufacturer, as the height of the attachmenthead according to DIN 7337 may vary.• The clamping thickness results from thethickness of the material to be riveted plus anadditional value of 2 mm to ensure that theclosing head is perfectly formed. In accor-dance with this clamping thickness the corre-sponding shaft length is determined in thetables provided by the rivet manufacturers.(lmin. = 14 mm)

Important:Since during riveting many factors may havean influence on the exact tolerance of therivets of 0.3 mm (e.g. rivet head tolerance), werecommend that you make a test on a façadepanel. Please always remove the protective foil in theriveting area prior to riveting.

Please take the thermal expansion of thepanel into account when using threaded fas-teners outdoors. To avoid jamming, the holediameter in the panel must allow for theexpansion.Fastening without jamming is possible withfascia screws made of stainless steel withsealing washer (Fig. 1) that have beenapproved for construction. The screws mustbe suitable for the corresponding substructure(please note the information given by themanufacturer). The screws should be tight-ened with a torque wrench or screwdriver sothat the sealing washer is placed on the panelfor sealing the bore hole without exertingpressure onto the panel.Multi-step drills or sleeves having correspon-ding diameters are used for centrically drillingholes into the panel and the substructure andfor centrically fitting the rivet.

Important: Make sure to remove protective foil prior toscrewing.

Threaded fasteners for indoor use

Screws for sheet metal and wood with differ-ent head-shapes are suitable for indoor use(Fig. 2). They do not normally allow for anypanel expansion.Countersunk screws can be inserted by theusual countersinking method or by depressingthe aluminium surface into the panel. Whendepressing the aluminium surface, the holediameter in the panel must be larger than thescrew diameter..

Hot-air welding has proved useful for joiningthermoplastic plastics and for weldingALUCOBOND®. The plastic core and the plasticwelding rod are heated and welded withelectrical hot-air welding sets. The followingconditions are essential for good results:• Well prepared welding joint• Good quality welding rod• Clean hot air• Correct temperature• Correct contact pressure• Welding speed

Welding with rapid welding nozzle

(Fig. 1) The rapid welding nozzle method ensuresuniform heating of the core material and thewelding rod and thus results in a betterwelding quality. Rod A is inserted manually through nozzletongue B. By applying constant pressure to thenozzle tongue, the rod is pressed into the joint.

Preparing of welding jointFor butt-welding, the edges of theALUCOBOND® panels must be chamfered (Fig. 2).Before folding and welding ALUCOBOND®

panels, grooves have to be routed into thepanels using corresponding milling cutters(Fig. 3).As the plastic core oxydizes relatively quicklywhen exposed to air, welding should be com-pleted within 24 hours after chamfering.

Welding rodPlease use the following quality:Polyethylene, soft, Type: 1800-hColour: black, diameter: 3-4 mmThe outer layer (oxide layer) of the weldingrod should be removed with emery clothimmediately before welding. Please chamferthe starting end of the rod to approx. 45°.

TemperatureThe following air temperature is required forhot-air welding:ALUCOBOND®: 265°C +/- 5°CThe temperature must be continuouslyadjustable and is measured with a mercurythermometer or bimetal measuring unit 5 mmfrom the nozzle point. To measure the temper-ature, please take off the rapid welding nozzle.

Contact PressureThe required pressure to the nozzle shoe(rapid welding nozzle) should be approx. 3 kp.

Hot-air welding setsWe recommend that the Leister hot-airwelding set, Type DIODE PID, be used inconnection with the ventilator, Type MINOR.

Skimming the welding seamA scraper blade or knife is used at a very flatangle to shave the welding seam as soon as ithas cooled down. For visible welding joints,the seam on butt and corner welds is removedusing a crescent-shaped knife (Fig. 4).

A uniform and solid fit of thesections is obtained by pressing the sectionsides together prior to inserting the panels.Butt joint, corner and edge sections are avail-able for panels of 3, 4 and 6 mm. Please askfor our stock list. For fascia cladding applications specialaluminium sections are provided for clampconnections.For further information on ALUCOBOND®

special sections and types for fasciacladdings please ask for the respectivedocumentation.

Lacquering of mill-finished ALUCOBOND® surfaces

21

Surfacetreatment

Customer requirements for special colourshades of ALUCOBOND® composite panels are met in small amounts by overlacqueringstandard stove-lacquered ALUCOBOND®

surfaces or mill-finished surfaces.

The composition of lacquer coating forALUCOBOND® is basically the same as thosefor mill-finished aluminium surfaces. However,it is advisable to be familiar with coatingsystems and materials as well as workingmethods for aluminium.

Please note:

• For general information on painting,lacquering and coating of aluminium werecommend the leaflets on ”02, 03, 012,015 surfaces” issued by

Gesamtverband der Aluminiumindustrie e. V.Postfach 105 463D-40045 DüsseldorfPhone +49 211 47 96 0Fax +49 211 47 96 408www.aluinfo.de

Please note:• The maximum permissible temperature

of the material (ALUCOBOND® panels)must not exceed 70°C when applyingfast-drying methods. During the dryingprocess at high temperatures theALUCOBOND® panels must be posi-tioned with great care to preventdeforming.

• ALUCOBOND® cut edges should not be incontact with organic solvents for a pro-longed period of time to avoid weakeningthe bond.

• ALUCOBOND® panels lacquered or overlac-quered at a later stage should not be bentor folded. The lacquer in the bends or foldsmay be damaged due to the low elasticityof the top coat.

• Upon request, we can name you lacquersuppliers who are able to apply lacquer thatcan be bent and folded.

• Only inferior lacquer adhesion can beachieved on core material exposed at cutedges.

• Please make a test prior to overlacqueringand follow the instructions of the lacquersuppliers.

Expert and regular cleaning not only maintainsthe aesthetic and representative finish ofstove-lacquered surfaces but also maintainstheir quality through the removal of dirt andaggressive deposits.Cleaning intervals depend on local environ-mental conditions and the resulting amount ofsoiling. Surfaces should be cleaned eithermanually or with a suitable cleaning devicefrom top to bottom.Please do not use any abrasive pads on lac-quered surfaces. We recommend that thecleaning agent be tried on an unobtrusive partof the object to be cleaned to check whetherthe surface is affected.Do not clean hot surfaces (>40° C) as the quick drying process may causeblemishes.
