Question
I have to make a IMC(intermediate metallic conduict) joint in theory. So, in general:
For 1 unit: metal casting vs powder metallurgy vs cold rolling (tell me the most expensive, the cheapest)
For mass production : metal casting vs powder metallurgy vs cold rolling (tell me the most expensive, the cheapest)
I bought this one(picture). It was made using cold rolling.

So, in general: For 1 unit: metal casting vs powder metallurgy vs cold rolling (tell me the most expensive, the cheapest) For mass production : metal casting vs powder metallurgy vs cold rolling (tell me the most expensive, the cheapest)Explanation / Answer
Let me start by explaining each process.
Metal casting: It includes preparing a pattern of the object you need to maufacture, using this pattern a dye is prepared. This dye, generally made of sand, is then poured with moulten metal which later solidifies to give you the casting object.
Powder metallurgy: It includes atomising or breaking down molten metal into fine powder by spraying molten metal and cooling it. This powder is then heated and pressurised to give you object.
Cold rolling: It includes rollers. Rollers shape the object by rolling under pressure and temperature is below crystellization temperature of material.
UNIT 1: cost wise processes are
Cold Rolling < Casting < Powder metallurgy
As you want to manufacture a 'joint' , it need to be elastic, should have good shock absorbing property. Hence powder metallurgy is not an option. The best select here would be cold rolling. It is cheap and imparts considerable desired properties to system.
Talking about mass production :
The time and energy required for cold rolling is much large. For mass production it will be more economical and time saving to produce dies and use metal casting process.
Hence for single unit cold rolling is more economical but for mass production casting is cheapest.
Powder metallurgy is highly expensive, also the material is porous and generally joints are not produced using it.
Also casting products require further surface finishing adding to there cost, this is not required in cold rolling. Yet for mass production casting is economical.
