Hand model processing in the mold, industrial production products required by a variety of molds and tools. Generally speaking, it is a tool used to make shaped articles. This tool is composed of various parts. Under the action of external force, the blank becomes a tool with specific shape and size. Different molds are made up of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the formed material. Known as the "mother of industry". Any commodity is made by mould. It can be said that there is no production without mould. It is widely used in various industries

例如：我们常见的电视机等家用电器、手机、电话机外壳等通讯设备等产品，是把塑料加热软件注进模具冷却成型生产出来的，电饭锅也是由金属平板用模具压成这样的形状。模具具有特定的轮廓或内腔形状，模具是工具，形状复杂，承受坯料的胀力，对结构强度、刚度、表面硬度、表面粗糙度和加工精度都有较高要求，模具生产的发展水平是机械制造水平的重要标志之一。

For example: our common TV and other household appliances, mobile phones, telephone shell and other communication equipment products are produced by injecting plastic heating software into the mold to cool and form, and the electric cooker is also made of metal plate pressed into such a shape by the mold. The mold has a specific contour or cavity shape. The mold is a tool with complex shape. It bears the expanding force of the blank and has high requirements for structural strength, stiffness, surface hardness, surface roughness and machining accuracy. The development level of mold production is one of the important indicators of the level of mechanical manufacturing.
            

实体模具制造的成本一般都是很高，大型的手办模型加工模具一套都是十几万几十万万乃几百万，尤其是医疗行业，上百万的模具很常见。如果在安装模具的过程中出现结构的不合理或者其他的问题，这样损失就很大了。所以一般先用手板确认外观、结构和功能，确认没有什么问题后再开模批量生产。

The cost of solid mold manufacturing is generally very high, a set of large-scale manual mold processing is tens of thousands or even millions, especially in the medical industry, millions of molds are very common. If there is unreasonable structure or other problems in the process of installing the mold, the loss will be great. So generally, first confirm the appearance, structure and function with the hand board, and then open the mold for mass production after confirming that there is no problem.

手办模型加工中模型，也可以称为样品、样件、样板，有些地方又把它叫做“首板”，即产品的首样板，在日本，又叫做“手办”，英文翻译是“rapidprototype”。手板是验证产品可行性的一步，是找出设计产品的缺陷、不足、弊端直接且有效的方式，从而对缺陷进行针对性的改善，直不能从个别手板模型中找出不足，通常还需要进行小批量的试产进而找出批量里的不足加以改善。

In the process of hand-made model processing, the model can also be called sample, sample piece and template. In some places, it is also called "first board", that is, the first template of the product. In Japan, it is also called "hand-made". The English translation is "rapid prototype". Hand board is a step to verify the feasibility of the product. It is a direct and effective way to find out the defects, deficiencies and drawbacks of the design product, so as to improve the defects. Until the deficiencies can not be found from individual hand board models, it is usually necessary to carry out small batch trial production, and then find out the deficiencies in the batch to improve.

通常一个手办模型加工产品刚研发或设计完成的产品均需要做手板模型，设计完成的产品一般不能做到很完善，甚无法使用，直接生产一旦有缺陷将全部报废，大大浪费人力和物力和时间。而手板一般情况是少数的样品，制作周期短，损耗人力物力少，很快地找出产品设计的不足进而改善，为产品定型量产提供充足的依据。

Usually, a hand-made model processing product just developed or designed needs to make a hand-made model. Generally, the designed product can not be perfect or even can not be used. Once there are defects in direct production, it will be scrapped, which greatly wastes manpower, material resources and time. In general, there are a few samples of hand boards, which have short production cycle and less manpower and material resources. We can quickly find out the shortcomings of product design and improve them, so as to provide sufficient basis for product finalization and mass production.
