The necessity of making a prototype.

First, check the design: the hand is not tight, it is visible and touchable, it can intuitively reflect the designer’s creativity in the form of real objects, avoiding "drawing well and making it not good-looking" Drawbacks. Because the production of the prototype is in the development of new products, the shape of the product is indispensable.

Second, check the structural design: because the hand board is assembleable, it can intuitively reflect the rationality of the structure, and the difficulty of installation is convenient for early detection and resolution of problems.

Third, avoid the risk of opening the mold: Because of the advanced nature of the prototype production, you can use the prototype to make products for publicity before the mold is developed, and even pre-sales, production preparation, and occupy the market in time.
