Board is also known as the first board, which is usually only needed for developing or designing products. The manual board of directors is the first step to verify the feasibility of products. It is the most direct and effective way to find out the defects and deficiencies of the designed products, so as to improve the defect target until the board sample can not be found from the personal hands. At this point, a small amount of pilot production usually needs to find out what is not enough to improve the batch.

　　根據(jù)生產(chǎn)中使用的材料，手板可分為塑料手板、硅膠手板、金屬手板、油泥手板。塑料手板:其原料為塑料，主要是一些塑料制品的手板，如電視機(jī)、顯示器、電話機(jī)等。塑料手板設(shè)計材料有ABS、PC、PMMA、PU等。ABS是更常用的手板設(shè)計材料;PC、PMMA為生產(chǎn)透明零件;PU用于生產(chǎn)小批量硅膠模具產(chǎn)品。ABS是機(jī)加工成塊狀，密度比注塑ABS低，加工后內(nèi)部分子鏈被切斷和斷裂。因此，ABS制的手板強(qiáng)度低，容易斷裂。不能用于銷售的產(chǎn)品。

　　According to the materials used in production, the hand board can be divided into plastic hand board, silica gel hand board, metal hand board and oil mud hand board. Plastic hand board: its raw material is plastic, mainly some plastic products, such as television, display, telephone, etc. The design materials of plastic hand board include ABS, PC, PMMA, PU, etc. ABS is the most commonly used design material for handboards; PC and PMMA are transparent parts; Pu is used to produce small batch of silica gel mold products. ABS is machined into blocks, the density of ABS is lower than that of injection molding. After processing, the internal molecular chain is cut and broken. Therefore, the hand board made of ABS has low strength and is easy to break. Products that cannot be used for sale.

　　塑料手板的設(shè)計工藝是數(shù)控加工和硅膠模具。另一種是激光快速成型，非常快。但由于其成品精度差，表面質(zhì)量不使用。CNC是數(shù)控銑削加工。該工具與普通加工沒有區(qū)別。區(qū)別在于銑削材料有ABS、PC、PMMA等材料。三維數(shù)據(jù)通過數(shù)控處理軟件編程。輸出到數(shù)控機(jī)床的訂單可以加工出我們需要的半成品。半成品經(jīng)拋光、噴漆、電鍍等工序加工而成。相當(dāng)于正式產(chǎn)品。是顯示和驗證外觀手板和功能手板的方式。

　　The design technology of plastic hand board is numerical control processing and silica gel mold. The other is laser rapid prototyping, very fast. However, due to the poor accuracy of the finished product, the surface quality is not recommended. CNC is CNC milling. There is no difference between this tool and ordinary machining. The difference is that milling materials include ABS, PC, PMMA and other materials. Three dimensional data is programmed by numerical control processing software. Orders output to CNC machine tools can process the semi-finished products we need. Semi finished products are processed by polishing, painting, electroplating and other processes. Equivalent to a formal product. It is the best way to display and verify the appearance and function hand boards.
