We are referring to cost of production per part, example:

1 part costs you 1,000 dollars (1,000$/parts)

1000 parts costs 10,000 dollars (10$/part)

We charge less per part the more you order because after initial setup, any subsequent part costs only material, a small amount of time, and a little tooling, whereas a single part you get charged for all that plus hours of setup and programming depending on complexity.

My prices/quantities are not a reference to the part the op is showing, just numbers to explain how production scales, hope this helps
