The cost of making a part or product will depend on the complexity, the material(s), the process requirements, the finish requriements, the testing/certification requirements, and where it is made. Every choice can have a significant effect on your bottom line as all these elements can cause the price to vary dramatically. It will cost more to manufacture domestically, but it will cost less for transportion/shipping. There is no tooling cost to CNC machine an aluminum part, but the cost of producing an aluminum diecast tool may be offset by the savings in the per-unit production cost. At BoxBuild, we can help you navigate all these choices and make well-informed decisions to best satisfy your needs.
