Molds and tools for industrial production. Generally speaking, it is a kind of tool for mold making. This tool is made up of various parts. Under the action of external force, the blank becomes a workpiece with specific shape and size. Different molds are made up of different parts. It can process the shape by changing the physical state of the material. It is known as the "mother of the industry". Any commodity is made of mould. It can be said that there is no mould production, which is widely used in various industries.

　　例如:我們常見的家用電器如電視機、手機、電話機殼等通訊設備產品，是將塑料加熱軟件注入模具冷卻成型生產，電飯煲也是由金屬板用模具壓制成這樣的形狀。模具有一個特定的外形或內腔形狀,模具是一個精密工具,形狀復雜,熊坯膨脹力,結構強度、剛度、表面硬度、表面粗糙度和加工精度有較高的要求,模具生產的發(fā)展是一種機械制造水平的重要標志。

　　For example, our common household appliances such as TV sets, mobile phones, telephone casings and other communication equipment products are produced by injecting plastic heating software into molds and cooling them. Rice cookers are also made of metal plates and pressed into such shapes by molds. The mold has a specific shape or cavity shape. The mold is a precision tool with complex shape, high requirements for the expansion force of bear blank, structural strength, rigidity, surface hardness, surface roughness and machining accuracy. The development of mold production is an important sign of the level of mechanical manufacturing.

　　物理模具制造的成本一般都很高，一套大型模具是幾萬乃幾百萬，尤其是在醫(yī)療行業(yè)，幾百萬的模具是很常見的。如果模具在安裝過程中出現(xiàn)結構不合理或其他問題，這樣的損失很大。所以一般先要確認手板的外觀、結構和功能，確認沒有問題后再開模量產。

　　The cost of physical mold manufacturing is generally very high. A set of large mold is tens of thousands or even millions, especially in the medical industry, millions of mold is very common. If the die has unreasonable structure or other problems in the process of installation, the loss will be great. Therefore, it is generally necessary to confirm the appearance, structure and function of the hand board first, and then open the mold for mass production after confirming that there is no problem.

　　手版，也可以叫樣版，樣版，樣版，樣版，有些地方叫“版”，也就是產品的版，在日本，也叫“手版”，英文翻譯是“rapidprototype”。步來驗證產品的可行性是找到更直接和有效的方法來找出缺陷,缺陷和缺點的設計產品,以提高缺陷有針對性的方式,直到缺陷無法找到從個人手的模型板。通常情況下，也有必要進行小批量試生產，然后找出其中的缺陷進行改進。

　　The manual version can also be called the sample version, sample version, sample version. In some places, it is called "the first version", that is, the first version of the product. In Japan, it is also called "the manual version". The English translation is "rapid prototype". The first step to verify the feasibility of the product is to find the most direct and effective way to find out the defects, defects and shortcomings of the design product, in order to improve the targeted way of defects, until the defects can not be found from the personal hands of the model board. Usually, it is necessary to carry out small batch trial production, and then find out the defects to improve.

　　通常，剛開發(fā)或設計的產品需要制作成手板模型。設計的產品不可能是的，甚不能使用。直接生產一旦出現(xiàn)缺陷，就會全部報廢，大大浪費人力、物力和時間。而手板的一般情況是樣本量少，生產周期短，人力物力損耗小，迅速找出產品設計的不足之處，然后加以改進，為產品定型設計提供充足的依據(jù)，進行量產。

　　Usually, newly developed or designed products need to be made into hand models. The designed product can't be perfect or even can't be used. Once there are defects in direct production, all of them will be scrapped, which greatly wastes manpower, material resources and time. However, the general situation of handboards is that the sample size is small, the production cycle is short, the loss of manpower and material resources is small, so we can quickly find out the shortcomings of product design, and then improve it to provide sufficient basis for product design and mass production.
