How do make reflections like in this image below?
Look at the metal part.

Here is a gradient example I made in PSP X.

Nothing special about it I guess. Just a studio-setup with a simple ligh-plane ligting the scene. Just try tu put a plane as a mesh-light at a position behind your camera and with a nice angle to your object and you should get similar results.

I tried a bunch of different stuff and it didn't work out.
Got an example?

Here you go, not exactly what you wanted, but had no time to test more. You'll see - it's just about the arangement of the light-planes, because it's of course the enviroment you see in the reflection.

Are you sure you're using the good material, becaude in our picture you linked, this is a studio setup with one plane or two to illuminate the scene

What is your metal, have you got a screenshot for us?

I am using a NK Data file Al.nk (Aluminum).

check your normals dude, they should face outwards.
Deaktivate normal smoothing for this hard edges, or subdivide these edges to a (very small) round bevel...

...Or as it's in blender, use the edgesplit modifier

@ zomB
The normals were pointing outward.
I didn't bother to bevel any edges
as this was just a quick test.

@Kram1032
What is the reason for using the split edge modifier?

Here is my lastest test.
I had to add an emitter plane x2 + 1/3 longer
then the cylinder to get it to look right.

Even if it's just a quick test: The edgesplit modifier gets rid of all your normalsmoothing problems

It splits edges, where the angle of the normals would be too small to look right. you should always use it, no matter if you use Indigo or Blender Internal - though *definitely* use it with Indigo

(especially where you have very sharp edges, like in that stick with it's 90° edge)

thanks, though, everyone could have found that one, as I already wrote that, like, hundred times or so? - And I'm not the only one, who repeatedly said that in the past.
There should be a "general hints" forum, where you *only* have hints. NO questions. And the subforums should contain:
Indigo
Violet
and all the Converters.

Hum, maybe I should poll that idea
