Classification of hand boards

早期的手板因為受到各種條件的限制，主要表現在其大部分工作都是用手工完成的，使得做出的手板工期長而很難嚴格達到外觀和結構圖紙的尺寸要求，因而其檢查外觀或結構合理性的功能也大打折扣。

Due to the limitations of various conditions, most of the work of the early hand board was completed manually, which made the hand board have a long construction period and difficult to strictly meet the dimensional requirements of the appearance and structure drawings. Therefore, its function of checking the rationality of the appearance or structure was greatly discounted.

隨著科技的進步，CAD和CAM技術的快速發展,為手板制造提供了更加好的技術支持，使得手板成為可能。

With the progress of science and technology and the rapid development of CAD and CAM technology, it provides better technical support for hand board manufacturing, making hand board possible.

另一方面，隨著社會競爭的日益激烈，產品的開發速度日益成為競爭的主要矛盾，而手板制造恰恰能提高產品開發的速度。

On the other hand, with the increasingly fierce social competition, the speed of product development has increasingly become the main contradiction of competition, and hand board manufacturing can improve the speed of product development.

正是在這種情況下，手板制造業便脫穎而出，成為一個相對獨立的行業而蓬勃發展起來。

It is in this case that the hand board manufacturing industry will stand out, become a relatively independent industry and flourish.

手板按照制作的手段分，可分為手工手板和數控手板：

According to the manufacturing methods, the hand board can be divided into hand board and NC hand board:

（1）手工手板：其主要工作量是用手工完成的。

(1) Manual hand board: its main workload is completed by hand.

（2）數控手板：其主要工作量是用數控機床完成的，而根據所用設備的不同，又可分為激光快速成形

(2) CNC hand board: its main workload is completed by CNC machine tools, which can be divided into laser rapid prototyping according to different equipment

RP手板：主要是用激光快速成型技術生產出來的手板。

RP hand board: it is mainly produced by laser rapid prototyping technology.

CNC手板：主要是用加工生產出來的手板。

CNC hand board: it is mainly produced by processing.

要表現在它的快速性上，但是它主要是通過堆積技術成型，因而RP手板一般相對粗糙，而且對產品的壁厚有一定要求，比如說壁厚太薄便不能生產。

It should be reflected in its rapidity, but it is mainly formed by stacking technology. Therefore, RP hand board is generally relatively rough, and there are certain requirements for the wall thickness of the product. For example, if the wall thickness is too thin, it can not be produced.

CNC手板的優點體現在它能非常準確的反映圖紙所表達信息，而且CNC手板表面質量高，尤其在其完成表面噴涂和絲印后，甚比開模具后生產出來的產品還要光彩照人。因此，CNC手板制造愈來愈成為手板制造業的主流

The advantage of CNC hand board is that it can accurately reflect the information expressed in the drawing, and the surface quality of CNC hand board is high, especially after its surface spraying and silk screen printing, it is even more glorious than the products produced after opening the mold. Therefore, CNC hand board manufacturing has increasingly become the mainstream of hand board manufacturing industry

手板按照制作所用的材料分，可分為塑膠手板和金屬手板：

According to the materials used for making, the hand board can be divided into plastic hand board and metal hand board:

（1）塑膠手板：其原材料為塑膠，主要是一些塑膠產品的手板，比如電視機、顯示器、電話機等等。

(1) Plastic hand board: its raw material is plastic, mainly the hand board of some plastic products, such as TV, monitor, telephone, etc.

（2）金屬手板：其原材料為鋁鎂合金等金屬材料，主要是一些高產品的手板.比如筆記本電腦、單放機、MP3播放機、CD機等等。

(2) Metal hand board: its raw materials are aluminum magnesium alloy and other metal materials, mainly hand boards of some high products Such as notebook computer, single player, MP3 player, CD player, etc.

制作手板的必要性

Necessity of making hand board

（1）檢驗外觀設計

(1) Inspection of design

手板不僅是可視的，而且是可觸摸的，他可以很直觀的以實物的形式把設計師的創意反映出來，避免了“畫出來好看而做出來不好看”的弊端。因此手板制作在新品開發，產品外形推敲的過程中是必不可少的。

The hand board is not only visible, but also touchable. It can intuitively reflect the designer's creativity in the form of physical objects, avoiding the disadvantage of "drawing is good-looking but making is not good-looking". Therefore, hand board production is essential in the process of new product development and product shape deliberation.
