5 Tips for Perfect Anodising

• Anodising is an electrolytic process of oxidation
  of the metal surface. Basically, the surface of
  the corrosive material is coated with the non-
  corrosive material to prevent from rusting. These
  increases the durability of the metal and give it
  beautiful finishing.
• Anodizing is a complex chemical process, one tiny
  mistake can really ruin the job, so if you are
  planning to get your metal anodized, make sure
  you take care of all 5 tips, given below

Take care of the marks.

• In Anodizing what we always get too see, metal
  sent for anodizing have scratches on it. Remember
  well, scratches are not removed or covered by
  anodizing, it will appear. Before sending the
  metal for anodising, make sure that you remove
  all the scratches, otherwise it becomes a hurdle
  in getting the desired finishing. In some cases,
  the impact of the marks can be removed by
  chemical etching process, but then, it too ruins
  the finishing.

6
Packaging These is a very common mistake that
everyone does. Make sure that you package the
metals properly. Do not stick tape on the metal
while packaging, tapes leaves marks on the metal
behind, anodizer do not take effort to clean all
the metal, because they cannot check each piece
of metals. Package the metal in such a way that
it does not get rubbed by any other metal or any
hard material, for perfect anodizing it is very
essential that the metal does not have any marks
or scratches on it

• Welding
• If the meal is to be welded make sure that the
  metal is welded before it is anodized. The reason
  for that is, anodize is the oxide of the metal
  and it is highly resistive to electricity, it
  will be very difficult to weld, once the metal is
  anodized. Anyhow if you have to do welding after
  the anodizing, remove the anodize layer by the
  mechanical means or by caustic based chemical
  means like, oven cleaner etc.

In case you are welding the metal after it is
anodized, use 5356 welding rod for proper
finishing. TIG welding is used mainly for
aluminium, so make sure you do not use MIG  Do
not try to reshape the metalIf you have to form
or mould the metal in any you have to do it
before anodizing it. Do not try to bend the metal
or exert tension on the metal after it is
anodized. The anodize does cannot bear tensions,
it just breaks. For example, if you are trying
the anodized metal rod, the anodize will crack.
These fractures become opening for corrosion
9
Other important issuesIt is better to sent the
colour sample with the metal, sent for anodizing
or email them Remember well, not every metal can
be anodised, it is just few metals like,
aluminium, titanium and magnesium.Prevent from
touching the uncoated metal, your finger print in
many ways can ruin the finishing If the product
has other metal attached to it, remove it before
or let know the anodizer so he can mask It
properly.
