Whether your producing your own products or manufacturing parts for another company, your focus is on the chip-to-chip process. Manufacturing parts by the fastest, most cost effective means while producing the highest quality possible. The bottom line is that you get paid by making stuff, not figuring out how to make stuff. Most companies find that the resources it takes to develop the tooling and gaging ends up drastically cutting into their profit because it is not a fixed cost when completed in house. More times than not, developing the processes to manufacture the parts ends up cost a substantial amount more than was originally intended.
