The first sample of the product is called the model. The early industrial samples were handmade, so it's called the hand model. Since this is the first sample of products, so it’s also called the first model.
1.Inspection appearance design：
The model is not only visible, but also touchable. It can intuitively reflect the creative ideas of the designer in the form of the object, avoiding the malpractice of "drawing good looking and doing not good.” Therefore, the model production is essential in the process of the new product development and the product's appearance.
2.Inspection structure design：
Because the model can be assembled, it can directly reflect the rationality of the structure and the complexity of installation. It is easy to find problems early and solve problems.
3.Avoid the risk of direct vowin.cn/' target='_blank'>mold opening：
The cost of mold manufacturing is generally high. A biggish mold is worth hundreds of thousands to millions of millions. If the structure is not reasonable or other problems are found in the process of opening the mold, the loss can be larger. And model making can avoid this loss and reduce the risk of mold opening.
4.Make the time of the product ahead of time：
Because of the foresight of model making, customers can make use of model for product publicity, even pre sales, production preparation, and occupy the market early.
