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:我们常见的家用电器如电视机、手机、电话机壳等通讯设备产品，是将塑料加热软件注入模具冷却成型生产，电饭煲也是由金属板用模具压制成这样的形状。模具有一个特定的外形或内腔形状,模具是一个精密工具,形状复杂,熊坯膨胀力,结构强度、刚度、表面硬度、表面粗糙度和加工精度有较高的要求,模具生产的发展是一种机械制造水平的重要标志。

　　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，一套大型模具是几万乃几百万，尤其是在医疗行业，几百万的模具是很常见的。如果模具在安装过程中出现结构不合理或其他问题，这样的损失很大。所以一般先要确认手板的外观、结构和功能，确认没有问题后再开模量产。

　　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，也可以叫样版，样版，样版，样版，有些地方叫“版”，也就是产品的版，在日本，也叫“手版”，英文翻译是“rapidprototype”。步来验证产品的可行性是找到更直接和有效的方法来找出缺陷,缺陷和缺点的设计产品,以提高缺陷有针对性的方式,直到缺陷无法找到从个人手的模型板。通常情况下，也有必要进行小批量试生产，然后找出其中的缺陷进行改进。

　　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，刚开发或设计的产品需要制作成手板模型。设计的产品不可能是的，甚不能使用。直接生产一旦出现缺陷，就会全部报废，大大浪费人力、物力和时间。而手板的一般情况是样本量少，生产周期短，人力物力损耗小，迅速找出产品设计的不足之处，然后加以改进，为产品定型设计提供充足的依据，进行量产。

　　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.
