I can never encourage a client with a new product enough to prototype their product. Without a prototype that’s been tested, you won’t know if your product will function as it should. Not investing in a prototype is dangerous because the production parts are only as good as the information the factory is given (drawings or samples).
We have a group of U.S. engineering and prototyping companies that works in a variety of fields who can work with you to finalize the design of your product.
