Strictly speaking, if you hire us to do a design project for you, whether for a single part or a complete product, you expect to receive a workable design, and rightly so. And that is what you will get.
However, in addition you will receive an evaluation of how the part should be manufactured or assembled, based on its operational environment and your anticipated annual production volume. Nothing exists by itself. There are always interactions with other components, other products, not to mention the person who will be using it.
We care and we go above and beyond what is expected, in order to assist your success. Obviously, successful people, when they need additional help with new challenges, return to those who helped them become successful in the first place.
