I manage a manufacturing stamped metal parts/wire edm/progressive tool and die design shop. We have an in house design department for a lot of our projects, and rarely ever contract out. I’ve noticed a lot of similar businesses in my area have the same setup. I feel like in our industry it is easier to have your own designer team on site that understands the projects your working on and can make changes on the fly instead of contracting projects out.

Maybe for a small shop operation you could help but any decent established shop will have some designers/tool makers that can run these projects.

Good luck.
