The metal parts typically costs higher than plastic parts. The deviation can be a little higher or a lot higher depends on the process used. Here are some processes to manufacture metal parts.
Sheet metal fabrication: depending on the

mold’s structure, we can make sheet metal

molds in quick and cheap way. Due to sheet metal has better strengthen and good flexibility than plastic, it is widely used in reality.
CNC
machining: CNC
machining is necessary and easy way to process the part with highly complex in shape. Due to it’s high accurate,
CNC machining is always used in high accuracy and complex industry.
Pressure die casting: when you order medium or even high volume metal parts, the cost by CNC machining is extremely high. Then you can consider about
pressure die casting, making a die
casting mold is expensive, but result in lower part cost. The more part you produce, the lower part price you may obtain.
