In a long time ago, when customers developed new products, they all opened the mold directly, and they did not care whether the design of the drawings was reasonable, whether there were errors or loopholes. Due to the lack of testing and inspection before opening the mold, every time when they found that the products opened the mold had defects, they had caused irreparable losses. The hand model is different. It is one or several products made according to the 3D drawing of the product without opening the mold, which is used to check whether the appearance or structure is reasonable.

手板模型跟模具相比，它有如下不同：

Compared with the mold, the handboard model has the following differences:

                    

1、手板模型所花的費用比較少，主要是用來做測試用的，所以數量通常不會太多，而且由于CNC加工、真空復膜、3d打印等技術不斷地成熟，制作手板的費用相比以前已經大幅度下降。而直接制作模具的費用一般都是幾萬或者幾十萬不等，而醫療器械和機器人類型的模具費多的都在大百萬。此外，有些手板小批量來做可以直接充當商品在市場上銷售，其手板的美觀和精致度不亞于開模做出來的，而所花的費用還不及開模的十分之一。

1. The cost of handboard model is relatively small, which is mainly used for testing, so the quantity is usually not too much. Moreover, due to the continuous maturity of CNC processing, vacuum lamination, 3D printing and other technologies, the cost of making handboard has been greatly reduced compared with before. And the cost of direct production of mold is generally tens of thousands or hundreds of thousands, while the cost of medical equipment and robot mold is more than one million. In addition, some handboards are made in small quantities and can be directly used as commodities for sale in the market. The beauty and delicacy of the handboards are no less than that of the molds, and the cost is less than one tenth of that of the molds.

2、手板模型所用的時間少，一般而言，開模所花的時間是非常長的，少則半個月，多則幾個月甚更長。而做手板模型的周期非常短，一般幾天就可以了，如果是采用3d打印來做的話，速度更快，通常當天就行了。

2. Generally speaking, it takes a very long time to open the model, from half a month to several months or even longer. The period of making the model is very short, usually in a few days. If 3D printing is used, the speed is faster, usually on the same day.

3、手板模型可以在產品未上市之前當作樣品在展會上展示，提前做好新產品的宣傳，甚可以直接在展會上獲取訂單，而開模的話不具備這樣的優點。 綜上所述，手板模型比開模好在所花費用少、所花時間短等方面。

3. The model can be displayed as a sample at the exhibition before the product is put on the market, so as to promote the new product in advance, and even get the order directly at the exhibition. However, the model opening does not have such advantages. To sum up, the advantages of the hand model are less cost and shorter time.
