Routing

2.5-4mm
Alupanel can easily be folded by hand if a “V” shaped groove is milled on the rear of the panel. This can be done using a conventional router (available from your local DIY store) or CNC milling machine.

A minimum thickness of 0.3mm of the
bottom polyethylene must be left on the
bottom/back of the decorative face.

Cutting speed: 3000 – 5000 m/min
Feed speed: 25 – 30 m/min



Slotting

Grooves can also be easily cut using a
special cutting machine that comes
complete with a guide/jig .
The “V” shaped groove is automatically
cut into Alupanel, which can then be
easily folded by hand.



Drilling

Alupanel is easily drilled – we suggest
for best results, the use of bits
designed for drilling aluminium and
plastic are used. For large holes, a
drill bit with a locating point is required.

Cutting Angle: 100° - 140°
Helix Angle: 30° - 50°
Cutting Speed: 50 – 300 m/min
Feed Speed: 0.02 – 0.5mm/revolution
Hole Size: Screw width + 2mm



Bending with a Panel Folder

Use a folding table. Min inside radius
R=15xt (t=panel thickness)



Bending with a 3 roller panel bender


Untitled_14.gif
 
3-Roller panel bender is preferable for
bending large internal diameters.



Clamping and Bolting


Untitled_15.gif
 
Can be clamped with a serrated corner
joint and butt sections for Alupanel thickness of 3mm and 4mm.

When bolting, e=2D is the formula to use to calculate the distance of fixing to the end of the panel.



Shearing

Use a standard guillotine for this purpose. Ensure the top cover sheet is inserted properly.



Hot Air Welding

A polyethylene welding rod is available
for use with an electric hot air welding
set.



Spray Painting and Coating


Untitled_18.gif
 
Standard air drying painting acrylic or two part polyurethane coatings are suitable.



Riveting

With the usual equipment using rivets or blind rivets. For external use please take thermal expansion into account.

Hole size = Rivet Width + 2mm



Folding

Alupanel can easily be folded by slotting or routing a groove on the rear of the product, as described in the slotting and routing section.



Laminating and Photo Mounting

Alupanel can be laminated manually or
by machine using cast or calendared self adhesive foil. The quality of polyester finish ensures it does not come off if the foil is changed.

Photographs and images can be applied with adhesive film or wet dispersion adhesive. Panels must be clean and free from grease.

Screen + Digital Printing

There have been numerous inks tested
for compatibility and adherence to Alupanel. The use of water based inks is not advisable. Please pre-test a small area with the ink to ensure suitability of use with Alupanel.



Smoothing Edges

After cutting Alupanel, any rough edges
and burrs ,ay be removed using a file
with a rasp like effect. Always file along
the length of the panel.

Punching

Use a steel band tool on a punching
base for 2mm and 3mm thickness.
Conventional punching machines are
excellent for this process.



Applying Vinyl Letters and Sheet

Ensure panels are clean and free from
grease.

The application of vinyl is prefect for
Alupanel. The smooth flat surface
combined with the dimensional stability
enure a quality finish that will last.

Gluing

Use standard metal aluminium adhesives. Ensure you avoid contact with the polyethylene centre, some adhesives will attack and decay the core. The use of conventional double faced tapes is acceptable.
