ALUCOBOND is a prefabricated panel l ing
material, i.e. the surface of the standard panel
is either lacquered, anodised or mill-finished.
These surfaces are protected by a special foi l
during transport, storage and processing.
Nevertheless, the fol low ing information must
be observed w hen storing and handling the
panels:
The pal lets must be handled careful ly
during transport and unloading. Do not handle
open pallets.
Upon delivery the pallets must be examined
for any damage due to moisture (ALUCOBOND
panels that have become w et must be dried t o
avoid any spots or corrosion formi ng). Any
damage must be reported immediately and
confirmed by the forwarding agent.
Store the pallets so that they are protected
against any w etness penetrating due t o rain
and spray water and avoid any condensation
forming (e.g. when transporting cold panels to
warmer rooms).
Store the pallets stacked one over the other
(do not store ALUCOBOND panels standing
vert ically), wi th a maximum of 6 pallets of the
same format stacked on top of each other
(heavy pallets at the bottom).
Individual panels must be l i f ted of f the pal-
let by tw o people holding all four corners and
not drawn over each other. Carry the panels
vertically. Wear gloves to avoid staining.
If stacking panels, nothing should be put in
between to avoid markings.
The following should be observed asregards the ALUCOBOND protective foil:
Storage exceeding 6 months should be
avoided.
Strong f luctuations in temperature reduce
the long-term durability.
Do not mark the panel surface or protection
film with inks (markers), tapes or labels.
Solvent or plasticiser may penetrate the film
and affect the lacquered surface.
Should the protective foi l part ial ly come off
during processing, dirtied edges can occur in
the course of t ime.
Remove protective f i lm as soon as possible
after erection. Protective film that remain on
panels for an expanded period of exterior
exposure may be very difficult to remove.

Drilling
ALUCOBOND can be dri l led with tw ist dri l lsnormally used for aluminium and plastics onmachines common for metals.
Drill material:High-speed steel (HSS)
Tool geometry:Lip angle: 100 140
Dril l ing without burr is possible using the fol-lowing dri l ls:
spot facing cutter with centre-point.
A ng le o f w h ist : 30 45
e.g. Extreme 2 TM HSS-G M etal drill DIN 338 ofDe WALT, D-Idstein
Countersink
Three-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.
Counter cutting
ALUCOBOND can be cut to size with j igsaws, CNC machining centres and watertorches. Please cut abrasively w hen using awater torch. Pre-drilling of the panels is nec-essary when start ing the cut in the middle ofa panel as it is not possible to dri l l throughwith a water torch.
Shearing
ALUCOBOND is easily sheared with a guil lo-t ine. A sl ight drawing of t he 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.
Punching
ALUCOBOND panels of any t hickness can bepunched with conventional sheet punchingmachines. For clean cuts pl ease use evenlyground tools and the narrowest possible cut-
ting gap (0.1 mm). This punching method a lsocauses a sl ight draw ing of the panel coversheet. Holes of a minimum diameter of 4 mmcan be punched. The minimum w idth of w ebbetween hole edges is also 4 mm.

Bending
ALUCOBOND 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 i sfor ALUCOBOND andALUCOBOND plus r = 10 x t
for 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 prot otype should bemade.
The surface should be protected from damageby affixing plastic film or i nserting polyethyleneof 1 2 mm thickness or plastic f i lm stripsduring processing.
The panel surface must be free from anyadhesive materi al (e.g. labels, etc.).
Important:W hen bending A LUCOBOND with ananodized surface, the bent area i s brighter.
Bending with a brake press
(Fig. 1)ALUCOBOND, l ike sheet metal, is easilyformed with a brake press. The air-bendingprocess is used w hen forming w ith a brakepress.
The A LUCOBOND 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 protec t ive fo i l t h ickness +punch diameter + 15 mm
The minimum side length of the bent partshould be 5 times t he ALUCOBOND thickness.
Bending with a folding machine
(Fig. 2)W hen working with f olding machines, thepanel to be bent is clamped between tw ocheeks. The projecting e dge is bent aroun d
the upper clamping cheek and former usingthe movable swivel bar. The bending radius isdetermined by interchangeable formersattached to the upper clamping cheek.
Bending with aroll bending machine
ALUCOBOND can be bent with sheet metalroll bending machines mainly w ith 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 from
swarf before pro cessing ALUCOBOND
. W erecommend ground rolls to avoid damagingthe cover sheets.

Routing and Folding Technique
and Designfor individual Shaping
Advantages
The convincing advantages of the routing andfolding techniques are:
M i n i mum invest m en t
Simple operat ing 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 l ikefascia claddings, roof edgings, corner pieces,
column casings and many more are possible Versat i le fo rmabil i t y
Good ec onom y
Shapes are not rest ric ted by machinedimensions
Folding wi thout cut t ing, therefore nobuckling 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
Method
ALUCOBOND 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 mil l ingcutters, whereby the aluminium cover sheet atthe front and part of the polyethylene core areretained. The small thickness of the remainingmaterial then allow s 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, o n 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 wit h an anodizedsurface, the edges are bright er.

Technique
Fixing
ALUCOBOND can be joined by means ofstandard processes used in metal and plasticstechnology.
If A LUCOBOND is to be joined to structuralparts of metals other than aluminium, or iffasteners (e.g. bolts, screw s) are to be used,the fol low ing material guidelines should beobserved:
Fasteners and structural parts made of alu-minium, plastic or stainless steel should besuitable for the assembly with ALUCOBOND.
W hen using other materials please insertinsulating washers etc. or apply protectivecoating to prevent corrosion.
Please take the t hermal expansion of the panelinto account f or outdoor use of ALUCOBOND
to avoid jamming or deformation.
The minimum gap depends on the expectedexpansion of the panel.
Please refer t o processing recommendationsfor rivets and bolts for additi onal measures toprevent jamming.
The linear t hermal expansion of ALUCOBOND
is determined by t he aluminium cover sheets.
At a temperaturedifference of 100C thelongitudinal expansion is 2.4mm/m.

ALUCOBOND panels can be fastened together
or joined to other materials with rivets common
to aluminium constructions.
For outdoor use and for use in areas of high
humidity, aluminium blind rivets w ith stainless
steel mandrils should be used to prevent ugly
corrosive edges. When using aluminium blind
rivets with steel mandrels, the mandrel shoulddrop out after riveting (detachable version).
Countersunk rivets are suitable for indoor use
only.
For outdoor use please note:
For outdoor use aluminium blind rivets thathave been approved for construction with a5 mm shaft diameter and an rivet head diameterof 11 or 14 mm are used.
Please take the thermal expansion of thepanel into a ccount (2.4 mm/ m/ 100C). Toavoid jamming, the hole in the panel must belarge enough to allow for expansion.
W ith the shaf t of the r ivet f i t t ing c losely tothe edge of the hole, the rivet head mustcover over 1 mm of the area surrounding thehole.
M ul t i -step dr i lls or hole gauges hav ingcorresponding diameters are used forcentrically drilling holes into the panel and thesubstructure and for centrically fitting the rivet.
Rivet at tachment j igs are used for f i t t ingblind rivets wit hout jamming allowing for atolerance of 0.3 mm. M ake sure to use rivetattachment jigs and rivets from the samemanufacturer, as the height of the rivet headaccording to DIN 7337 m ay vary.
The clamping thickness results from thethickness of the material to be riveted plus anaddit ional 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.
(min. = 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 faade
panel.Please alw ays remove the protective foil in theriveting area prior to riveting.

Hot-air welding has proved useful for joiningthermoplastic plastics and for w eldingALUCOBOND. The plastic core and the plasticw elding rod are heated and welded wit helectrical hot-air w elding sets. The fol low ingconditions are essential for good results:
Wel l p repared welding join t
Good quali ty welding rod Clean hot a i r
Correct temperature
Correct contact pressure
We l di ng speed
Welding withrapid welding nozzle
(Fig. 1)The rapid welding nozzle method ensuresuniform heating of the core material and the
w elding rod and thus results in a betterw elding quality.
Rod A is inserted manual ly through nozzletongue B. By applying constant pressure to thenozzle tongue, the rod is pressed into the joi nt.
Preparing of welding joint
For 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 pl astic core oxydizes relatively quicklywhen exposed to air, welding should be com-pleted w ithin 24 hours after chamfering.
Welding rod
Please use the following quality:Polyethylene, soft, Type: 1800-hColour: black, diameter: 3-4 mm
The outer layer (oxide layer) of the weldingrod should be removed with emery clothimmediately before welding. Please chamfer
the starting end of the rod to approx. 45.
Temperature
The following air t emperature is required forhot-air welding:
ALUCOBOND: 265C +/- 5C
The temperature must be continuouslyadjustable and is measured with a mercurythermometer or bimetal measuring unit 5 mmfrom t he nozzle point . To measure the t emper-ature, please take off the rapid w elding nozzle.
Contact Pressure
The required pressure to the nozzle shoe(rapid w elding n ozzle) should be approx. 3 kp.
Hot-air welding sets
W e recommend that the Leister hot-airwelding set, Type DIODE PID, be used in
connection w ith the ventil ator, Type M INOR.
Skimming the welding seam
A scraper blade or knife is used at a very f latangle 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).

Lacquering of mill-finished
ALUCOBOND surfaces
21
Surfacetreatment
Customer requirements for special colourshades of ALUCOBOND composite panelsare met in small amounts at our plant byoverlacquering standard stove-lacqueredALUCOBOND surfaces or mill-finishedsurfaces.
The composition of lacquer coating for
ALUCOBOND is basically the same as those
for mill-finished aluminium surfaces. However,
it is advisable to be famil iar w ith coating
systems and materials as well as working
methods for aluminium.
Please note:

Please note:
The maximumpermissible temperature
of the material (ALUCOBOND
panels)must not exceed 70C when applyingfast-drying methods. During the dryingprocess at high temperatures theALUCOBOND panels must be posi-tionedwith great care to preventdeforming.
ALUCOBOND cut edges should not be incontact with organic solvents for a pro-longed period of t ime t o avoid weakeningthe bond.
ALUCOBOND panels lacquered or overlac-quered at a later stage should not be bentor folded. The lacquer in the bends or folds
may 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 condit ions and the result ing amount ofsoiling. Surfaces should be cleaned either
manually or w ith a suitable cleaning devicefrom top to bottom.
Please do not u se 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 (>40C) asthe quick drying process may causeblemishes.
