Manufacturing Process

Hi,

I'm looking in to the design of a desk lamp for a project. Can anyone tell me what the most likely manufacturing process is used to make the bulb cover / housing (below)? It is a 3D hollow shape made of metal so I am thinking High Pressure Die Casting may be suitable but the setup costs may be high. It doesn't really matter which process I choose but I was just curious as to how it is actually done because this type of info is hard to come by!

likely done as a stamping.

Deep drawing or spinning.

Thanks guys.

I actually ended going with deep drawing so that's good news :)
