horizontal or vertical anodizing plants - italtecno · suction directly over tanks with hoods ......
TRANSCRIPT
According to their design they can be hori-zontal or vertical for extruded profiles, onlyhorizontal for sheets and accessories.
Flexibility:• Possibility of anodizing extruded profi-
les, sheets and accessories • Possibility of using different clamping
systems and optimizing racking times• Easy change of lay-out of tanks with pos-
sibility of expansion
Initial investment:• Lower cost than vertical plants
Environment:• Max 25% of the drag-out compared to
horizontal plants • Good recycling possibilities
High quality • Uniformity of layer thickness distribution • Optimum rinsing efficiency • Automatic chemical replenishment and
correction 24 hours/day
High Productivity • Fast clamping at only one edge of the
profile • Less floor space • Automatic process by means of PC con-
trol
Cost control • Low man-hour cost
For both horizontal and vertical it ispossible to choose three lay-outs:
• One way anodizing: This line has theadvantage of having the loading andunloading area from the same side fortop efficiency of the staff involved andforesees a large parking area and easyreturn of anodic bars.
• In-line anodizing: This line has theadvantage of simple design and relati-vely small room needed.
• “U” shape anodizing: This line has theadvantage of easy material flow
1. Tanks: they are made of steel or stain-less steel, suitably lined with soft PVC orcompletely made of Polypropylene, 15-20 mm. thick and suitably stiffened withsteel or stainless steel sections. The steelsurfaces are sand-blasted and finishedwith acid-proof epoxy paint. Tanks forvertical anodizing plants are usuallymade of concrete and lined with suita-ble material (like polypropylene or pol-yethylene).
2. Machinery: they are housed in separa-ted rooms to protect them from corrosi-ve fumes, with easy access for mainte-nance
3. Complete fume exhaust systems:suction directly over tanks with hoodscapable of guaranteeing an internalatmosphere free from harmful and cor-rosive fumes.

Anodizing
Possibility to add neutralising towers(scrubbers) for expulsion of fumes/gastreated to guarantee conformity withlocal environmental regulations gover-ning emissions.
4. Bridge cranes: they are designed toprovide all transfer (handling) and cor-rect draining procedures within thetimes required and are suitable for ope-ration in manual or fully automaticmode (the latter when combined withcomputerized systems). Semi-automaticsystems are also available.Loading and unloading designed forthe maximum comfort of the workersand for automatic working
5. Air agitation: it maintains a constanttemperature within the bath. Air agita-tion is carried out by low-pressure blowerswhich blow chilled air across the treat-ment and rinsing tanks through a perfo-rated PVC or Polypropylene tube held atthe bottom of the anodizing tank.
6. Pulse rectifiers: they are designed inaccordance with the latest technologiesto provide:
- Better quality and more uniform oxide- Reduction of 20-30% of anodizing
times- Energy saving of 5-7%- Remote control panel with computer
for presetting the oxide thicknessrequired.
7. Cooling systems:- Pre-assembled modules with plate-
type heat exchanger and acid resistantpumps (stainless steel) complete withdigital thermo-regulation unit.
- Pre-assembled accumulation tank forchilled water, with circulation pumps.
- Refrigerating unit with air or watercondensation depending on climaticconditions on site.
8. FREEAL recycling: it is a regeneration
system for sulphuric acid of anodizingtanks with removal of aluminium sul-phate. Fully automatic system on one ormore tanks controlled by PLC. Fully automatic regeneration cycle withtap water.
9. TECNO 4: it is a special computerizedpower supply for electro-pigmentationwith DC-AC waveform: simple program-ming allows the achievement of com-pletely uniform colouring even withlarge loads (equivalent to maximumcapacity of rectifiers).
10. Auxiliary equipment for electro-colou-ring tank: they are recommended inview of the high output, which can beobtained with TECNO 4 power supply.
- Filtering and heat regulation unit withplate type heat exchanger.
- Mixing system with automatic mete-ring of chemicals controlled by ampe-re hour meter.
11. Multicolour: it is an innovative electro-colouring technology for the produc-tion of new colours for architecturaland decorative applications.
12. Auxiliary equipment for sealing tanks:Pre-assembled unit consisting of filterpump and mixing system with automa-tic metering of chemicals controlled bymetering pump programmed on thebasis of daily out-put.
13. Demineralizing units: automatic ormanual, single or DUPLEX units (one inoperation and one in stand-by).
14. Tanks heating system: it is provided bylow pressure steam generators and hea-ting coils. Electrical heating coils arealso available.
15. Waste water treatment plants: they areplants for treatment of waste water andconcentrates, mud thickening system,

final filtering with possibility of recy-cling up to 70% of the treated water.Our treatment plants fully respect theenvironmental regulations in force.
16. Brushing machine with stainless steelbrushes: it is designed for mechanicalpre-treatment of the profiles, fullyhydraulic unit with water lubrication.Advantages:
- Elimination of slight defects andextrusion lines
- Scotch-Brite finishing (linear satinfinish)
- Reduction of 50-80% in chemicalsatin-finishing times and caustic sodaconsumption
- Reduction of aluminium waste
17. SATMAC machine: it is designed for amechanical finish similar to the oneobtained chemically in etching baths in10-20 minutes.
18. Packing systems: conventional or fullyautomatic with final weighing.
19. Main control board for the powersupply of the different machines com-posing the anodizing plant.
20. Computerized system for plant mana-gement: main part is the software pac-kage suitable for storage of the produc-tion data (treatment time-surface trea-ted per load (m2)-Oxide thickness) andfor the automatic control of the whole
