The prototype model, also known as the first version of the product, is the prototype product of the trial production product. The design staff uses the prototype product to check whether there are defects in the appearance design or modeling design, structural defects, and some products have no defects in the design drawings, but they can't be used or even manufactured. Therefore, we must first make the model of the hand board.

而塑膠手板模型則是數控技術的通稱，現在在工業生產生產制造上邊一般指數控車床。數控車床和傳統式的人力數控車床和銑工不一樣，大家只需在數控車床上邊鍵入相對的主要參數，就可以命令設備把原料生產加工成相對的產品。并且生產加工速率和精 密度都很高。如今一些較為好的數控車床，還能夠立即導進CAD工程圖紙開展生產制造。只必須導進工程圖紙，迅速，設備就能自動式生產制造出相匹配的產品，而且保證無庸置疑，十分便捷。

And the plastic hand model is the general name of numerical control technology, now in industrial production on the general index control lathe. Numerical control lathe is different from traditional manual numerical control lathe and milling worker. You only need to input relative main parameters on the numerical control lathe, and then you can command the equipment to produce and process raw materials into relative products. And the processing speed and precision are very high. Nowadays, some of the better CNC lathes can be imported into CAD engineering drawings immediately for manufacturing. As long as the engineering drawings are imported, the equipment can produce matching products automatically and quickly, which is undoubtedly convenient.
               

不難看出，塑膠手板模型的特性是生產制造速度更快，高精度，便捷靠譜，能夠釋放技術工程師和室內設計師的兩手。室內設計師在設計方案了自身的產品以后，只需把工程圖紙鍵入到數控車床，迅速就能獲得原形產品開展剖析，而無需像之前一樣等上三五天才可以取得手板模型，大大的耽擱了評定時間。并且設備對設計圖紙的復原也肯定真 正，不必擔心手板模型和設計圖紙不符。

It is not difficult to see that the characteristics of plastic hand model are faster production speed, high precision, convenient and reliable, which can release the hands of technical engineers and interior designers. After designing their own products, interior designers only need to input the engineering drawings into the CNC lathe to quickly obtain the prototype products for analysis, instead of waiting three or five days to obtain the hand model as before, which greatly delays the evaluation time. Moreover, the restoration of the design drawings by the equipment must be true, and there is no need to worry about the inconsistency between the hand model and the design drawings.

可是，塑膠手板模型制做也是有其缺陷，即成本費相對性昂貴。由于好的數控車床比較貴。自然，一次應用的價錢不容易劃算?？墒?，假如一些大企業比競爭者更早地發布產品，那么它要占領市場主動權，那么此項項目投資也被覺得具備成本效益。

However, the production of plastic hand model also has its defects, that is, relative cost and high price. Because good numerical control lathe price is quite expensive. Naturally, it's not easy to get a good price for one application. However, if some large enterprises release their products earlier than their competitors, then they want to take the initiative in the market, and the project investment is considered cost-effective.
