What are the necessity of prototype planning?

The simple point of CNC prototype model planning is to make one or several first based on product appearance drawings or structural drawings without opening the mold to check the functional model of the appearance or structure. (1) Check the appearance planning. The hand-board model planning is not only visible, but also touchable. It can intuitively reflect the planner's ideas in the form of objects, preventing 'drawing beautifully but making it unsightly' The disadvantages. Therefore, prototype making is indispensable in the process of new product development and product shape refinement.　　(2) Check the structure planning　　Because the prototype is installable, it can intuitively reflect the reasonableness of the structure and the difficulty of the installation. It is convenient to find and solve problems early. (3) Prevent the danger of opening the mold directly. Because the cost of mold production is generally high, relatively large molds are worth hundreds of thousands or even millions. If unreasonable structure or other problems are found in the process of opening the mold, its loss may be lost. Think about it. Prototype production can prevent this loss and reduce the risk of mold opening.　　(4) Make the product come out much earlier 　　Because of the advancement of prototype model planning, you can use the prototype to promote the product before the mold is developed, and even the early sales and production preparation work, so as to occupy the market as soon as possible.
