Designing a product completes only after a prototype is made and tested for all its functions. Cogent can provide you the support to build prototype of a part, may it be metal or plastic.
We could make a machine prototype, by bulding only the core functional area and test it for effectiveness. It is possible to eleminate risk in a big way if we choose to build proto types of core functions before embarking on a full throttled journey to build a machine with many automatic functions.
In order to build the proto type, it would be good to use low cost products as the robustness is not the main expectation.
