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：我們常見的電視機(jī)等家用電器、手機(jī)、電話機(jī)外殼等通訊設(shè)備等產(chǎn)品，是把塑料加熱軟件注進(jìn)模具冷卻成型生產(chǎn)出來的，電飯鍋也是由金屬平板用模具壓成這樣的形狀。模具具有特定的輪廓或內(nèi)腔形狀，模具是工具，形狀復(fù)雜，承受坯料的脹力，對結(jié)構(gòu)強(qiáng)度、剛度、表面硬度、表面粗糙度和加工精度都有較高要求，模具生產(chǎn)的發(fā)展水平是機(jī)械制造水平的重要標(biāo)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.
            

實(shí)體模具制造的成本一般都是很高，大型的手辦模型加工模具一套都是十幾萬幾十萬萬乃幾百萬，尤其是醫(yī)療行業(yè)，上百萬的模具很常見。如果在安裝模具的過程中出現(xiàn)結(jié)構(gòu)的不合理或者其他的問題，這樣損失就很大了。所以一般先用手板確認(rèn)外觀、結(jié)構(gòu)和功能，確認(rèn)沒有什么問題后再開模批量生產(chǎn)。

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.

手辦模型加工中模型，也可以稱為樣品、樣件、樣板，有些地方又把它叫做“首板”，即產(chǎn)品的首樣板，在日本，又叫做“手辦”，英文翻譯是“rapidprototype”。手板是驗(yàn)證產(chǎn)品可行性的一步，是找出設(shè)計(jì)產(chǎn)品的缺陷、不足、弊端直接且有效的方式，從而對缺陷進(jìn)行針對性的改善，直不能從個(gè)別手板模型中找出不足，通常還需要進(jìn)行小批量的試產(chǎn)進(jìn)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.

通常一個(gè)手辦模型加工產(chǎn)品剛研發(fā)或設(shè)計(jì)完成的產(chǎn)品均需要做手板模型，設(shè)計(jì)完成的產(chǎn)品一般不能做到很完善，甚無法使用，直接生產(chǎn)一旦有缺陷將全部報(bào)廢，大大浪費(fèi)人力和物力和時(shí)間。而手板一般情況是少數(shù)的樣品，制作周期短，損耗人力物力少，很快地找出產(chǎn)品設(shè)計(jì)的不足進(jìn)而改善，為產(chǎn)品定型量產(chǎn)提供充足的依據(jù)。

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.
